Water News» Heloika Energy wins US $34m contract for drinking water project in Gambia

T

he government of Gambia, through the Ministry of Fisheries, Water Resources and National Assembly Matters (MoFWR) has awarded a contract for the implementation of a drinking water project in the country.

Approximately 150 communities will benefit from this project mostly residents of rural and Peri-urban communities, as well as deprived urban communities with poor waste management practices, whose environment is facing increasing climate change threats such as flash flooding and periods of extreme drought. As a mechanism for sustainable management of the borehole facilities developed under CSRWASHDEP, including the 103 mentioned above, the MoFWR has established Water Committees in all the beneficiary communities. The committees will be in charge of the management and proper upkeep of the facilities throughout the Country.

The contract was awarded to Heloika Energy and it entails improve the drinking water supply to the county’s population. The project involves drilling of 103 boreholes in the West African country at a total cost of approximately US $34m.

Heloika Energy will implement the project in two phases. The first phase will see the construction of 50 large boreholes while the second phase will deliver 53 mini boreholes at an investment of US $19m and US $15m respectively.

The drilling of these boreholes is a component of the Climate Smart Wash Development Project (CSRWASHDEP), which is under

the MoFWR. The CSRWASHDEP’s main objectives are to increase access to safe, clean drinking water, and sustainable water supply. It also aims to provide sanitation and hygiene facilities to the targeted communities in The Gambia.

Each beneficiary community, through their Water Committee, is required to open and maintain a Bank Account with a minimum amount of US $25, 000 deposited on yearly basis for a period of 60 months. This money will serve as a fix deposit for future maintenance of the water facilities.

SunCulture to distribute solar-powered water pumps across Africa

S

outh Africa has unveiled a US$61 billion plan for the next ten years to counter water shortages by improving its water-supply and storage infrastructure.

According to the company which was founded in 2013, in Africa, 80% of families depend on agriculture for their livelihood, but only 4% use irrigation due to the instability of the electricity grid. On top of this comes drought, one of the consequences of climate change.

Kenyan start-up SunCulture has announced plans to disseminate solar-powered water pumps in seven African countries. This is after the company carried out a financial mobilisation raised US $14m for the development.

The company which provides solar water pumps for irrigation received the funding from Energy Access Ventures (EAV), Electricité de France (EDF), Acumen Capital Partners (ACP) and Dream Project Incubators (DPI). SunCulture was advised in this transaction by London-based Ekta Partners and received advisory support (market opportunity and competitive landscape) from CrossBoundary, a company providing solar energy to commercial and

The water pumps are equipped with 300 W solar panels and a 440 Wh battery storage system. These batteries can hold four light bulbs, two telephones and a plug-in submersible water pump. industrial (C&I) customers in Africa.

With this capital, SunCulture plans to distribute its solar water pumps for irrigation in Ethiopia, Uganda, Zambia, Senegal, Togo and Ivory Coast. They will be used by farmers who will have the opportunity to multiply their income.

Industry Tips» Optimising efficiency of solarpowered pumping systems

B

panels deliver the highest possible power in various irradiation and ambient temperature conditions.

MG’s electromechanical specialists, with extensive experience in gearing, have extended their solutions service to include solar inverters and drives, which are designed to enhance efficiency of photovoltaic (PV) systems.

“For optimum performance of the PV pump system, we believe it is critical for users to fully understand the control strategy of the system and to consider factors like where to install the drive, condensation issues, the temperature range and the back-up supply.”

“PV modules – which use daylight to generate electricity – are gaining popularity globally as a form of renewable energy that is clean, emission-free, sustainable, safe and cost efficient. Through the use of environmentally-friendly PV technology to generate electrical power, companies in South Africa are finding effective solutions to combat the country’s grave electricity crisis,” explains Mick Baugh, electronics manager, BMG’s electromechanical division.

Control strategy Simpler solar-powered drives for pumping applications operate as under-voltage regulators, lowering the pump speed (thus reducing the absorbed power) when the DC voltage reaches a minimum voltage setpoint. This simple control mode negatively impacts performance of the PV modules, since they operate at a non-optimal voltage.

“The benefits of using eco-friendly solar powered pumps for irrigation, animal farming and community water supply, include an uninterrupted water supply during the day and independence from the unreliable grid. In addition, advanced PV systems require minimal maintenance, which is an important advantage in remote areas where servicing is difficult. indar

In advanced controllers, the drive works to obtain the maximum power from solar panels by keeping the DC voltage at the optimum point (MPP = Max Power Point).

Drives that operate at a constant DC voltage must be selected depending on the electrical characteristics of the installed PV system and should optimise the hydraulic efficiency of the pump.

BMG specialists recommend the use of Vacon solar-powered drives that feature MPPT (Maximum Power Point tracking) control

to ensure an optimal operation voltage for PV modules in pump applications. These highly-efficient MPPT controllers provide extended running hours, with an earlier start and later stop. Consequently, more water is pumped per watt peak (Wp) of installed PV modules, leading to reduced investment costs and a quicker payback period. MPPT controllers detect instantaneous irradiance or temperature variations and omit local maximums, which are generated in partial shading conditions or from degraded modules in the PV array.

Cabinet or outdoor installations Conventional solar pump inverters are usually IP20 or 21 devices that are installed inside a cabinet along with components, including fuses, a power switch, lightening protection and door-mounted LEDs/ bulbs. BMG specialists do not recommend this system because cabinets need to be ventilated to avoid overheating of the enclosed elements. Overheating produces derating and reduces lifetime of the drive. Airflow though the cabinet needs to be filtered to avoid dust collection and filters must be periodically cleaned and replaced, which increases risks and adds to maintenance costs.

BMG’s Vacon IP66 drive solutions for outdoor installations consist of a small enclosure (replacing conventional big cabinets) which are separated from the drive – to house the mains switch and surge protection device. The Vacon IP66 drive can be installed outdoors without any reliability risk and does not require maintenance, as there are no filters to clean or replace. Drives can be mounted in the same structure of the PV modules, taking advantage of their shading to avoid overheating and thus a derating, due to direct sun on the drive.

This ground-level system is fitted with Light Emitting Diodes (LEDs) which allow external visibility of operating conditions of the drive, including power-on, run, ready and fault. An IP66 display panel provides detailed information of the drive, like running speed and MWh readings. This

“Solar-powered pumping systems, which are particularly popular in remote areas where electricity is unavailable, require a solar inverter to convert direct current (DC) generated by solar panels into alternating current (AC) for use in industrial, commercial and residential applications.

A key differentiator in the selection of the correct inverter, is its ability to run the motor pump at the optimal working voltage and power ratings, to ensure solar 12

enclosure, which is separated from the drive, gives the installer flexibility when designing a cabinet that is suitable to run a pump in different layouts.

Condensation In conventional solar-powered pumping installations, intermittent operation during the day and internal temperatures changes between night and day, promote cyclical condensation-evaporation processes inside of the drive. IP 20/21 drives installed inside a cabinet are sensitive to internal condensation and require temperature-controlled heaters.

This can be a problem in solar-powered pumping systems because an AC grid is not normally available on remote sites. For this reason, anti-condensation solutions that do not require an energy supply, should be considered.

An advantage of BMG’s Vacon IP66 IP 66/ NEMA 4X drives for outdoor installations is they are well protected against the ingress of water and dust and a specially designed GOREŽ vent effectively prevents condensation, without the need for a heater.

Temperature range Solar-powered pumping systems are normally installed in areas where high temperatures can be a problem for the PV system. For this reason, it is critical to consider the maximum ambient temperature on site when selecting the appropriate drive model. This maximum temperature should be contained in the operating temperature range for the drive – preferably in the range without derating, to avoid power losses and to extend the service life of the drive.

Users should take into account that the temperature inside a cabinet where an IP 20/21 drive is installed is always higher than the ambient temperature. It is important to consider the overheating effect due to direct sunlight if the cabinet is not mounted in the shade.

BMG supports its extensive range of electromechanical products with a technical advisory and support service, tailored to meet the precise specifications of contractors, designers and the end-user.

How to identify best quality water tanks

Image Courtesy: Vectus Kenya Limited

I

dentifying best quality water tanks in kenya can be a daunting task especially with the saturation in the market, yet water plays a very essential role in human lives and the lack of it can turn disastrous.

According to UN Water, Water scarcity can mean scarcity in availability due to physical shortage, or scarcity in access due to the failure of institutions to ensure a regular supply or due to a lack of adequate infrastructure.

To ensure steady supply and availability of clean water, a convenient storage is important. Pumps Africa Magazine looks at best quality water tanks in Kenya that can be used for the above purpose.

The best types of water tanks are; Plastic water tanks and Steel water tanks.

Here are some of the features of best quality water tanks in Kenya.

Plastic Water tanks For best performance, a water tank should be rust resistant to keep the water from being contaminated with rust particles. A rust resistant tank will also serve for a long time hence durability. When buying steel tank for water storage or any other purpose, always go for stainless steel.

The tank should be able to total block UV light (sunlight) so that water growing plants like algae, and other living organisms that require sunlight to survive in water will not have a chance of living in the tank. This leaves the tank’s water safe for drinking.

Black plastic water tank is recommended for purpose of UV light protection.

A good water tank should be easy to clean as overtime, solid dirt from atmosphere and the collected water settle at the bottom of the tank.

Durability is key for long service life; look out for water tanks that have to warranties as they will not serve you for a long time. Some manufacturers will provide warranties and guarantee specific number of years a tank will serve.

Plastic water tanks are preferred for various reasons including: ease of installation, durability, UV light blockage design, availability in various sizes and capacities, costs, ease of cleaning and low maintenance.

Always ask the supplier or manufacturer for installation guidelines when buying your plastic water tank.

Preet Chheda, CEO Vectus Kenya Ltd advises that plastic tanks should only be bought from manufacturers who use UV material. He clarifies that UV material can be any other colour but the preferred option should be black.

“The best way to drill the outlet or inlet, would be by using a drilling machine, this will keep the warranty of the tanks safe and will also not damage the tank due to a change in the temperature,” he adds.

Steel water tanks Steel water tanks, however not as popular

14

as the plastic water tanks, are also a good choice. They are highly durable, stainless steel tanks are rust resistant, unlike other metallic tanks. They come with big water storage capacities, most steel tanks are used for community water supply or by municipality water utilities.

They are free from UV light penetration as they are sealed in all sides and the shiny surface helps reflect sunlight.

Steel tanks can be installed on the ground, underground and can also be raised. Each installation mode has specific guidelines that should be followed to ensure proper and sage installation. Always seek for professional services when installing your tank.

How to check for durability Chhed instructs that the best way to determine the quality of the tank, is to check and compare the weights of different tanks from different manufacturers. “The simple rule is, the more the weight of the tank the thicker the walls of the tank are, so more strength to withstand the pressure of water.”

He advises against pressing the tank on its sides to determine how light a tank is in weight. The best way, he recommends is to look out for the total weight of a tank.

The lighter the tank, the less likely it is to hold the pressure of the water that is stored within.

If your water can be reached in a shallow well, lake or river, you can use a surface water pump which will deliver more water to your crops for a given solar panel size.

Borehole water which is more than 10m below the surface will usually need a submersible pump, and probably a larger installation with a fixed solar panel to get enough water.

At Futurepump we are fanatical about helping

Tip!

The greater the vertical distance that the pump needs to lift water, the harder it will be working.

That means you’ll either get less water, or you’ll need larger solar panels.

3 PORTABILITY Is your solar pump system flexible enough to move around your farm or rent to your neighbours?

Some pumps are designed to be used with large solar panels which are too big to be carried around and so are fixed on a concreted steel frame, or mounted on a roof. That is fine if you can overcome theft concerns and don’t need to irrigate in different parts of your farm.

However,

4 SERVICING Thousands of pumps lie useless because servicing wasn’t considered.

Make sure your supplier will stand behind their product.

Whatever people say, even the most robust solar pump is at some point, going to need servicing.

These machines work hard. Don’t hope it won’t happen, ask yourself what you’ll do when it does.

So unless you plan to just throw away your pump and buy a new one, you’ll need to think about where you can get spare parts or technical support. Is the pump designed to be userserviceable? What manufacturer’s warranties are available? Ask your local distributor if they will be there to help you service your pump and how long is the warranty

Futurepump’s offering includes: 1. 5 Year parts warranty on all pumps.

2. Common spare parts and the tools you need are supplied in the box.

3. YouTube servicing videos.

4. Free global support ticket service.

5. Additional technical support via your local dealer.

5 TOLERANCE OF SAND, MUD AND RUNNING DRY Is your pump actually designed for farm work?

By their nature, farms are often muddy or sandy places, but surprisingly not all pumps on the market are tolerant of sand and may quickly wear out or fail if the water isn’t completely clean. You may need to ensure the inlet pipe has a good filter or screen, to keep out sand particles and other debris which cause damage to many pumps. The Futurepump is highly tolerant of sand, by the way.

Oh, and ask your pump supplier if the pump will be OK with running dry. An unattended pump can easily end up pumping air from time to

Global Off-Grid Solar Market Report Semi-Annual Sales and Impact Data

I

African market was expected to see strong and continued growth, yet in comparison to the first half of 2019, sales in East Africa dropped by 11%.

It has also put a spotlight on the need for all people to have access to basic protections and basic services. This includes electricity.

Without it, we cannot power health centres, cannot share critical information and cannot re-energise our economies. Today, nearly 800 million people still live without electricity – no power to stay connected, no power to support a business, no power to turn on a light.

The economic impact of COVID-19, compounded by the worst locust infestations in decades and heavy flooding in key markets all contributed to this decline. Sales in West and Central Africa remained relatively stable, however, this was primarily due to bulk procurements in specific countries made prior to the pandemic. Whilst the drop in Sub-Saharan Africa was still a curb on progress, public support for the sector seen in a number of countries helped to mitigate even greater impact.

n 2020, the COVID-19 pandemic swept the globe causing unprecedented impact on families, healthcare systems and economies. It has led to a devastating loss of life and had disastrous effects on national welfare.

The off-grid solar sector is committed to combating energy poverty and driving economic activity. In 2019, it was making remarkable progress, with record-breaking sales. Continued growth in 2020 was expected to boost the sector’s 370,000 clean energy jobs and enable it to power millions of new homes and businesses. However, like many other sectors, COVID-19 has led to a slowdown in progress and threatens its ability to reach and sustain the 13% year-onyear growth rate needed to meet SDG73 – affordable, reliable, sustainable, and modern energy for all.

In the first half of 2020, global sales of off-grid solar lighting products fell 26% compared to the same period in 2019, with only 3 million units sold. These were the lowest volumes recorded since 2014. While all off-grid solar product categories were affected by the challenging conditions, declines in sales of entry-level products, often purchased by customers living on the lowest incomes, were most severe. Sales of portable lanterns without mobile charging dropped below 1 million for the first time since record keeping began.

Globally, all regions registered a slowdown.

The worst affected was South Asia, where the challenges seen in the market in previous years were exacerbated by the COVID-19 pandemic. This led to a nearly 60% drop in sales in comparison with the first half of 2019. Prior to the crisis, the Sub-Saharan

Sales of efficient appliances were also affected by the COVID-19 crisis. Sales of fans saw the largest absolute decline compared to the first half of 2019, linked to stringent lockdown measures in their biggest market, South Asia. Solar water pumps and refrigeration units also saw a halt in growth.

Sales of TVs showed a more positive story, with companies indicating this may be due to customers recognising the value of entertainment and access to information in the early stages of the lockdown. However, although sales volumes were equivalent to the first half of 2019, they dipped by 21% compared to July-December instead of continuing their strong upward trend.

In the months ahead, COVID-19 is expected to slow economic growth in low-income countries to the slowest pace in 25 years6 and push over 70 million more people into extreme poverty. This causes significant concern for energy access and other development goals. In the last six months alone, an estimated 5 million people missed the opportunity to benefit from clean, safe solar electricity in their homes and businesses.

In addition, the exciting strides made by the solar water pump and refrigeration sectors – with their potential to transform agriculture and food security – have also slowed. This knock to progress has led the IEA to adjust its outlook on global energy access. When

looking at the expected energy access contributions from multiple technologies (national grid, mini-grid, off-grid), the latest data estimates that 660 million people worldwide will still live without electricity in 2030 in a baseline scenario, or 760 million in a delayed recovery scenario.

The challenges may appear overwhelming, but they can be overcome. A number of initiatives are already underway.

At the peak of the lockdown, many national governments gave off-grid solar ‘essential service’ status, enabling companies to continue their operations with the same exemptions as large-scale electricity utility companies. This not only kept the lights on for thousands of homes, it also expanded support for off-grid solutions outside of energy, education and environment ministries.

Driven by the sector’s leading investors and development partners, several industry relief efforts are also underway to provide the sector with financial, technical and operational support. At the same time, the industry itself has responded to the pandemic head on, with companies working to provide flexibility in customer financing, streamline operations and protect staff. These vital actions are a strong start. However, to regain the momentum seen in 2019, more is needed; from enhanced regulatory and policy support to the creation of dedicated initiatives to galvanise investment.

COVID-19 has slowed progress on energy poverty, yet it has also highlighted just how vital electricity is to combat the pandemic and drive recovery. To create healthier, more resilient communities and re-energise economies, the off-grid industry must get back on track. By working together, we can unlock the innovation, creativity and impact of the off-grid solar sector so it can continue to reach millions of energy poor families and help the world to build back better.

«Solar Energy Egyptian farmers to access solar irrigation pumps funding

E

gyptian farmers will now acquire solar irrigation pumps easily after International Finance Corporation (IFC) and the Agricultural bank of Egypt (ABE) formed a partnership to help the farmers access financing to purchase the solar irrigation systems. The partnership will help promote Egyptian farmers switch to Solar Irrigation Systems reducing their reliance on diesel-powered generators and boosting their productivity.

According to IFC, using solar power for water pumping could potentially save farmers an estimated US $875 million annually in diesel fuel costs, helping reduce greenhouse gas. ABE, one of the country’s largest banks in Egypt, will build capacity and design new financial products to enable

Egyptian farmers—most of whom lack direct access to grid electricity—to purchase and install solar irrigation pumps.

ABE Deputy Chairman – Sami Abdel Sadek, said, “Expanding the use of solar energy technology among farmers is part of our strategy to support agricultural and rural development in Egypt. It will also contribute to the country’s 2030 strategy to encourage agricultural investments and rationalize the use of resources, including energy, in the sector.”

Walid Labadi, IFC Country Manager for Egypt, Libya, and Yemen, added that the partnership with ABE will help provide clean energy to farmers at an affordable cost, while helping reduce greenhouse gas

emissions. Supporting the development of renewable energy and expanding access to finance are priorities for IFC in Egypt.

The partnership is part of IFC’s broader advisory work to strengthen Egypt’s clean technology sector and support entrepreneurship in the country.

Under the Cleantech Entrepreneurship and Market Development Project, IFC is helping select financial institutions build their capacity to offer financing facilities for off-grid photovoltaic (PV) systems in the agribusiness sector. The project is being implemented in partnership with the governments of Denmark, South Korea, and the Netherlands.

IFC—a member of the World Bank Group— is the largest global development institution focused on the private sector in emerging markets while ABE’s main objective is to help in the develope Egypt’s agricultural sector.

HDPE Pipe in Mining – A Better Approach

And if issues arise, system maintenance requires the pipe to be cut and repaired, which can be a time-consuming and costly endeavor. Along with installation and maintenance concerns, fusing HDPE pipe in mining applications is a dangerous task.

From the risk of injury when moving and operating fusing equipment to off-gasses and fumes, the fusion process comes with several safety concerns.

With these concerns in mind, Victaulic, the leading manufacturer of mechanical joining systems, developed a better approach.

Introducing a Better Way The Victaulic HDPE system provides a mechanical joining solution that replaces fusion and improves the way HDPE pipe in mining and other industries is installed and maintained. Designed for direct bury applications, Victaulic HDPE couplings are made with durable ductile iron housings and fluoropolymer-coated hardware.

M

ining is rooted in innovation. From the use of autonomous trucks and hauling equipment to advanced mineral extraction processes, technological advancements are evident. Pipeline systems are also experiencing this innovation, with the use of high-density polyethylene (HDPE) pipe in mining applications becoming more prevalent than ever before.

From non-process systems to metal and mineral recovery, the conversion from metal to HDPE pipe can be seen in a slew of applications. What’s more, is that mine operations that use HDPE pipe benefit from cost advantages to both their capital and operational expenses. Yet joining HDPE pipe in mining applications can be challenging due to harsh conditions, confined spaces, and remote or difficult environments – conditions which are characteristic of mines around the world.

However, traditional methods to install and maintain these HDPE systems, on the other hand, provide far fewer advantages.

Electrofusion or butt fusion, the traditional methods for joining HDPE pipe, are laborious and difficult tasks, even in the most pristine conditions. Joints are often susceptible to improper fusing due to surface contamination, poor weather or environmental conditions, or error in the fusion process by the installer. What makes matters worse is these joints cannot be verified for proper installation easily, leaving the system susceptible to future issues.

The Difficulties of Fusing Whether you’re installing a dewatering line, tailings, or process water piping, or even a fire protection system, the goal is to utilize an efficient joining method that is safe to install and easy to maintain – and that’s where HDPE pipe proves its advantages.

It’s flexible without the risk of kinking; it absorbs bumps; it can be dragged, and it can accommodate large temperature sings in exposed environments.

28

Installed on plain end pipe up to 14” using simple handle tools, the Victaulic system does not require certified technicians to install or maintain. The joints are comprised of 100 percent reusable material and eliminate any harsh fumes or gasses associated with fusing. This all adds up to a safer mine, with the added bonus of an installation time that is up to 10 times faster than fusing. And while the faster installation is ideal, proper installation is critical.

Victaulic understands this, providing joints that can be visually verified to ensure proper installation.

Along with these benefits, the Victaulic HDPE system is both reliable and easy to maintain. Should maintenance be required, couplings can be easily disassembled using simple hand tools and repaired or replaced within minutes. This time savings is valuable in mining applications, where downtime, planned or unplanned, can come at a high cost.

Reduce Cost. Compress Schedule.

Improve Safety.

The advantages of installing HDPE in mining applications are evident. Yet to truly benefit from these piping systems, installation and maintenance should be seamless and safe. Replacing fusion with Victaulic HDPE solutions reduces costs, compresses project schedules, and increases on-site safety. Couple this with all-weather installation, limited risk of improper assembly, and ease of maintenance, and the advantages are clear.

Mining» Hybrid solutions are the most effective way to deliver reliable clean power to remote off-grid mining operations in Africa

by Tarik Sfendla, Market Development Manager, Africa chez Wärtsilä Energy Business

T

he energy markets are undergoing a massive transformation as governments around the world transition away from fossil fuels towards the integration of renewable energy. This trend is clearly visible in the mining industry as demonstrated by recent power projects in South America and in Australia. According to Bloomberg New Energy Finance, in 2018, mines purchased 1 GW of renewable energy generation assets; this amount tripled to reach approximately 3.5 GW in 2019, 90% of which consist of hybrid solutions.

with lifecycle services to provide “alwayson” power. The plant secures uninterrupted off-grid power supply, eliminating revenue losses from power shortages, while the O&M agreement is tailored to the mine’s day-to-day performance requirements.

Maintenance schedules are optimised to minimize costs and production downtime and enhance fuel efficiency. As a result, fuel savings of around 4%, representing $2 million USD, were achieved in the first year of operation. The flexibility of the installation will also facilitate the transition to renewables over the project lifetime.

Electricity demand for the mining industry is expected to increase significantly in the coming years as increased mine depth, harder rock and greater water desalination needs lead to higher energy intensity for the industry.

Whilst electrification of operations and vehicles is reducing certain emissions and generating cost savings, stakeholder targets to reduce emissions as part of the EESG (Environmental, Economic, Social & Governance) plans, is increasing the renewable share of the energy mix, which of course requires high flexibility in generation to balance intermittent renewables.

In Africa, the mining sector faces inherent challenges, access to the power grid and grid reliability being the most significant.

With most electricity supply coming from conventional power plants (coal, oil or gas), operators are challenged on the one hand with highly volatile operating expenses due to rising fuel costs, and by inefficient, unreliable power supply leading to costly production disruption and revenue losses on the other. Weak infrastructure and water availability compound the challenges for mines, particularly in remote, off-grid locations.

The combination of these trends and particularities of the African markets are setting the scene for the integration of renewables for the mining sector. A recent study by McKinsey[1] showed that moving to renewable electricity sources is becoming increasingly feasible, even in off-grid

environments, as the cost of electricity storage is set to decline by 50% from 2017 to 2030. This is especially good news for Africa where the cost of solar energy generation could be among the lowest in the world.

It also represents a huge opportunity for operators in Africa, where Wärtsilä has developed a range of competitive strategies to deliver efficient and reliable power supply solutions to support the mining sector on its path towards a renewable energy future.

In Tanzania, the Geita gold mine, was experiencing reliability issues and power shortages as its aging power plant was reaching the end of its useful life. It needed a reliable power generation solution to support its growing operations. Wärtsilä delivered a 40 MW flexible power plant and agreed a 10-year operation and maintenance (O&M) package, integrating technology

In Burkina Faso, Wärtsilä has delivered a 15 MWp solar photovoltaic (PV) power plant to the independent power producer (IPP) Essakane Solar SAS, which supplies the Ekkasine gold mine. The solar PV plant was constructed next to a 55 MW power plant running on heavy fuel oil. The engine power plant provides backup, while the solar farm produces energy during the day. The capability to control and optimise the usage of the solar PV power and engines enables the gold mine to reduce its fuel consumption by an estimated 6 million litres per year and its annual CO2 emissions by 18,500 tons.

Energy Storage technologies are the true game changer The integration of energy storage technologies will be the real game changer, enabling the industry to take full advantage of cheap and plentiful solar power. They have the unique ability to provide a buffer between supply and demand by delivering or storing energy whenever it is most needed. They will become the key building block of the stable infrastructure needed to improve grid reliability and security. Hybrid solutions, combining flexible thermal generation with storage and solar power operations are now a realistic and cost-effective solution, as the levelled cost of electricity (LCOE) is lower than ever, and costs of storage are set to decline.

In Mali, at the Fekola mine, located in a remote area with no connection to any larger grid, Wärtsilä is providing an off-grid hybrid

solution to provide and maintain microgrid stability. The project combines a 30 MW solar PV plant, a 17.3 MW / 15.4 MW energy storage facility and GEMS, Wärtsilä’s advanced energy management system, with the mine’s existing 64 MW power generator to improve power reliability, reduce heavy fuel consumption, save costs and reduce CO2 emissions.

GEMS is a ground-breaking tool, using smart algorithms to dispatch energy storage and multiple generation assets (thermal and renewable) with the right reserve level to maintain high grid reliability for the mine. Gensets are switched off as solar output increases and are restarted based on forecasted data including load demand and weather. The sophistication of GEMS enables energy production optimization to ensure the lowest LCOE. In addition to ensuring microgrid stability, the project is expected to generate longterm annual savings of 13.1 million litres of heavy fuel oil and reduce the mine’s carbon footprint by approximately 39,000 tons per year. This hybrid storage project is the first of its kind in Mali and in the mining sector, demonstrating the growing case for clean energy and its sustainable and economic potential for mines in Africa and elsewhere.

Increasing energy reliability and lowering operating costs are essential for the mining sector. The optimal solution to solve the power challenges must allow for fast starting with high off-grid availability, high fuel efficiency, fast load following and partload efficiency to allow high penetration of renewables.

The answer lies in a combination of advanced flexible energy generation strategies and the smart use of renewables to guarantee the delivery of efficient and reliable power in remote off-grid locations. Advanced energy management systems are the key technological element required to support the huge inflows of power from intermittent sources.

With an extensive portfolio of energy storage and flexible solutions for energy intensive operations, in Africa and the rest of the world, Wärtsilä, is the partner of choice to support the mining sector achieve its sustainability and cost saving goals.

How to unclog Industrial Water Pumps

H

ose tracking is at the bottom in the pecking order of priorities in the sphere of increasing efficiency in mining. But if mining companies are really hell-bent on realising value across-the-board in their operations, every available avenue to accomplish this has to be fully exploited.

To this end, vast opportunities lie in the management of hydraulic hose and fittings.

When overly large solids or certain types of debris enter the water, some pumps are more prone to clogging. Clogged pumps with a full or partial blockage can quickly pose severe damage to the rest of your equipment,

cause backups and can potentially delay your projects. To ensure your pump systems operate to their fullest potential, read what our experts have to say below to help determine a root cause and offer solutions on how to unclog industrial water pumps, so you can resume smooth operation.

Determine How the Clog Started During high flows such as heavy rain and weather events, municipal waste water stations and sewer systems can back up storm drains or full systems with debris such as clothing / rags, trash, large solids, etc.

Additionally, inappropriately flushed items

like grease may be a contributing factor to a blockage of sewer systems. This detritus can quickly build up and cause an emergency wastewater crisis situation that can potentially flood residential neighborhoods or clog whole sewage systems. On construction jobsites, mines, and quarries, a downed pump can cause costly delays such as shorter pump life, added management time, and extended personnel time.

First, you must identify the source(s) of the problem. Often, the source is either inappropriately flushed items such as rags or fats, oils and grease (FOG) which are

known to cause problematic fatbergs or stormwater debris buildup. After assessment of contributing factors, and determining whether you’re dealing with a full clog (where the pump is no longer working) or a partial clog (which decreases water flow), a plan to clear the clog and mitigate future clogging issues may be implemented. For mitigation, solutions such as installation of trash baskets, bar screens or agitators may be installed, or screening / upstream filtering might be necessary, however each has its pros and cons.

Some pump companies have adapted to the debris issue by adding chopper impellers to their pumps which are made to handle this type of material and literally chop debris when it enters system. Unfortunately retrofits or new pumps with this option are slow to enter the field. Municipalities however are now purchasing submersible chopper pumps for their lift stations more than ever to decrease any potential risk of blockage or pump downtime.

One of the most reliable ways to clear a clogged pump is to physically remove the clogging debris by releasing the vacuum, disconnecting the suction tube and letting the water rush back through the suction tube to flush out the debris, however the debris

still remains in the water to be pumped.

MWI discourages the use of a suction screen on a bypass as we feel it is easier to remove the suction hose and reach up in the volute to pull the rags or other debris from the impeller, than lift the entire suction hose out of a manhole and clean off the screen.

Although cumbersome or frustrating, physical removal may be a necessary part of any debris management plan.

Consider New Equipmentconsider new equipment Selecting the right pump is crucial to maintaining a smooth flow and preventing clogs. To avoid clogs, consider investing in equipment that can handle water containing debris and cut down on clogs such as trash pumps. MWI offers trash pumps built for any environment from smaller sewer bypass and job site dewatering all the way up to full sewage treatment plant / pumping station bypass with 200% larger handling capacities for solids up to 6” and a flow of 20MGD. The EPA confirms that “548 million tons of C&D debris were generated in the United States, in 2015—more than twice the amount of generated municipal waste.” Trash pumps such as our self-priming Primerite™ have larger impellers so they can handle small branches, pebbles, and other debris from
