High-efficiency lighting retrofit Reduce your costs with efficient lighting Lighting accounts for 18 percent of electricity consumed annually in the United States, with another 4 to 5 percent used to remove waste heat generated by lighting. Commercial office building operators spend about 29 percent of their operating budgets on utility bills. Lighting, cooling, and ventilation account for more than 60 percent of these buildings’ electricity use. If you’ve never upgraded to more efficient lighting, opportunities likely exist to enhance your efficiency, reduce energy costs, and reap attractive returns on your investment with our rebates. But remember, rebates and lower operating costs aren’t the only advantages of high-efficiency lighting. Research indicates that efficient lighting also can contribute to productivity, quality control, security, safety and reduced maintenance costs.

Eligibility All commercial, industrial, and agricultural customers in Minnesota are eligible. Eligible retrofits include T5 and T8 lamps, electronic ballasts, compact fluorescent lighting (CFL) fixtures and lamps, efficient high-intensity discharge (HID) lighting, light-emitting diode (LED) systems, and lighting controls.

We recommend storing old fluorescent lamps and HID lamps according to the Minnesota Pollution Control Agency (MPCA) procedures described below: ■■ Store

in an area and a manner that will prevent breakage. ■■ Post notices to show employees where and how to store lamps. ■■ If storage on-site is not possible, transport the lamps to a storage location. A hazardous waste manifest is not needed as long as lamps are transported to a site within Minnesota. Shipping papers are required.

■■ Ballasts

may contain polychlorinated biphenyls (PCBs). Storage and disposal of PCB ballasts must conform to the requirements of the Environmental Protection Agency and the MPCA. ■■ For more information about fluorescent lamps, high‑intensity discharge lamps, and ballast storage and disposal requirements, contact your local county recycling offices. They may have recycling programs in your area. Or call the MPCA at 800-657-3864.

Efficient electric motors Efficient motors can reduce costs Motors can account for up to 75 percent of the total electricity costs in industrial plants and up to 50 percent of electricity costs in commercial buildings. Replacing used or burned-out standardefficiency motors with energy-efficient motors can reduce your energy use and operating costs. Energy-efficient motors have other advantages too. They’re quieter. Because they operate at lower temperatures, they last longer. Their superior design and construction lead to reduced downtime and maintenance costs. And they have a higher power factor.

Federal legislation brings change Our motor rebate program encourages our industrial, commercial, and agricultural customers to purchase efficient new, replacement, or retrofit motors. ■■ 2007

EISA legislation set NEMA Premium®as the efficiency standard for 1 to 200 horsepower totally enclosed fan-cooled (TEFC) and open drip-proof (ODP) motors manufactured after December 2010. of TEFC and ODP motors must exceed NEMA Premium efficiency to qualify for incentives for new motors and replacement of nonoperating motors.

■■ Efficiency

■■ TEFC

and ODP motors replaced prior to failure must meet NEMA Premium efficiency levels to qualify for incentives.

■■ Availability

of certain motors meeting efficiency requirements may be limited.

■■ Rebates

will not exceed 75 percent of project costs or 75 percent of customer’s annual electric bill.

See the tables starting on page 7 for details on minimum efficiency levels needed to qualify for rebates.

Taking Care of Business

High rebate, permanent savings Our motor rebate program offers up to $9,000 for each qualifying energy-efficient motor installation. But your savings don’t end with the rebate. Operating energy-efficient motors costs as much as 10 percent less than standard-efficiency motors. That fact, plus the rebate, quickly overcomes the higher initial cost.

Eligibility All Otter Tail Power Company industrial, commercial, and agricultural customers in Minnesota qualify for rebates. Motors must meet or exceed qualifying efficiency levels and: ■■ Range

from 1 to 500 hp and be AC 3-phase with speeds of 3600, 1800, or 1200 RPM.

■■ Test

in accordance with IEEE Standard 112, Test Method B.

Motors exceeding 500 horsepower may qualify under our commercial and industrial grant program (see page 15). Contact your Otter Tail Power Company representative for details.

Guidelines Higher rebates are available for TEFC and ODP motors replaced prior to failure. Special efficiency requirements and rebates for explosion-proof motors exist. Otter Tail Power Company reserves the right to inspect and verify motor locations and installations before issuing rebates and to verify actual energy savings after installation.


Motor selection tips One of the most important factors in motor selection is sizing. Undersized motors sometimes operate under overload conditions. That leads to increased downtime and reduced life expectancy. On the other hand, oversized motors contribute to reduced power factor and operate at a reduced efficiency, which could add to your energy bill.

For these reasons, and to achieve maximum energy savings, we recommend that you always match motor ratings to your load requirements. Consider the actual load levels, both starting and running, and the expected duration of each load.

Adjustable-speed drives Adjustable-speed drives improve motor performance and efficiency Induction motors are the workhorses of commercial enterprises and are used in virtually every manufacturing plant and office building. The largest energy savings in induction motor systems often lies not in the motor but in the controls governing the motor’s operation. Adjustable-speed drives (ASDs), also known as variable-speed drives (VSDs), variable-frequency drives (VFDs), or variable-frequency inverters (VFIs), are used to modify or control motor operation, which improves drive system performance and efficiency. For example, adjustable-speed drives can match the speed of an AC motor to the requirements of a fluctuating load, such as a pump that moves changing fluid volumes during production. When this happens, the control valves, dampers, or other throttling mechanisms can be removed (or locked in full open positions), dramatically improving energy efficiency and reducing energy expenses by more than 50 percent.

Adjustable-speed drive rebates ■■ Rebate

of $100 per horsepower for process and other nonseasonal centrifugal applications.

■■ Rebate

of $60 per horsepower for seasonal and HVAC centrifugal applications.

Guidelines ■■ Rebates

cover ASD installation on motors from 1 to 500 horsepower operating under centrifugal loads.

■■ Rebates

will not exceed 75 percent of installed ASD cost.

■■ Rebates

will not exceed 75 percent of your annual electric bill.

CIP rebates will not exceed 75 percent of installed costs or 75 percent of customer’s annual electric bill. Qualified customers may select 1.9 percent financing in lieu of CIP rebates. Funding limits and other program guidelines and limitations apply.

Energy-efficient refrigeration A hot deal for cool customers Commercial refrigeration accounts for 16 percent to 18 percent of commercial energy use and as much as 70 percent of electricity consumption in some grocery stores. Just a 10 percent reduction in energy costs for a supermarket is the equivalent of increasing net profit margin by 16 percent. Because grocery store profit margins are so thin— as low as 1 percent—every dollar in evergy savings is the equivalent of increasing sales by $59. When you install energy-efficient equipment you’ll save in two ways: 1. Lower electric bills.

Rebate information Many rebates are available in four areas of commercial refrigeration. 1. Refrigeration rack system upgrades. 2. Stand-alone condensing units. 3. Display cases and walk-ins. 4. Preventive maintenance and cleaning measures. The amount of your rebate and the amount of your savings will depend on the size of your refrigeration unit and the number of rebates that apply to your system. See the chart below for details.

2. Up-front rebates on certain types of energy-efficient refrigeration equipment. Commercial refrigeration rebates Measure

Heat pumps Heat pumps offer heating and cooling No matter how cold it gets, heat always is in the air and ground. Heat pumps are designed to move that heat into your building to keep it warm and out of your building to keep it cool. Because moving heat is much cheaper than making it, heat pumps provide year-round comfort and savings. They work well by themselves or as part of dual-fuel systems.

Geothermal heat pump The geothermal heat pump is the most economical heating and cooling system on today’s market. It can deliver more than four units of heat for each unit of energy it uses and can help you save up to 70 percent on your annual heating costs!

Here’s how it works A special plastic pipe is buried in the ground. The pipe is filled with an environmentally-friendly liquid that flows to a heat pump inside your building. In cold weather the earth warms the liquid in the pipe. The heat pump extracts the heat in the heat exchanger and warms your building. In hot weather the heat pump reverses and works like an air conditioner, moving heat from indoors to outdoors, keeping the building comfortably cool. Closed-loop and open-loop configurations enable a geothermal heat pump to fit nearly any building site. And by optimizing the loop field configuration, installation costs may be reduced.

Rebates on heat pumps installed as replacements to natural gas heating systems or delivered fuels (propane and fuel oil) may be limited. Financing is not available on heat pumps installed as replacements for fossil fuel heating.

Air-source heat pump Air-source heat pumps, with supplemental electric heating for colder periods, will reduce heating costs by 30 percent to 50 percent when installed on an off-peak rate. We recommend auxiliary electric heat, such as a plenum heater, to provide quick response for tempering cold air during extremely cold temperatures. At temperatures above 0° F air-source heat pumps operate at 200 percent or greater efficiency. New models can reduce cooling costs by 30 percent to 50 percent or more.

Here’s how it works During cold weather the air-source heat pump extracts heat from outside air and moves it into indoor spaces to keep you warm. During warm weather the process is reversed to move heat from indoor spaces to the outside air to keep you cool.

Air-source heat pump rebate qualifications The rebate for an air-source heat pump is $400 per ton if it is labeled as ENERGY STAR or shows proof of the following: ■■ Split-system

installations must be rated with 15.0 or greater SEER, 12.5 EER, and 8.5 or greater HSPF.

■■ Package-terminal

heat pump installations must be rated with 12.0 or greater EER.

Rebates on heat pumps installed as replacements to natural gas heating systems or delivered fuels (propane and fuel oil) may be limited. Financing is not available on heat pumps installed as replacements for fossil fuel heating.

Compressed-air system audits Compressed air, often referred to as the “fourth utility” in industrial facilities, is a critical operations component. Common uses for compressed air include power tool operation, packaging, conveyors, automation equipment, and control systems. Compressed air is expensive to produce because only 20 percent to 25 percent of input electricity results in useful compressedair energy delivered to the plant’s air system. Identify ways to make your system more efficient and cost effective. This program provides incentives of 80 percent of the cost (up to $10,000 per audit) for customers who bring in

experts to complete compressed-air audits. The compressed-air audit provider must meet requirements we’ve set to ensure payment of incentives. Audit funds are limited. Based on the findings of your audit, you might also be eligible for additional financial help to make efficiency upgrades to your compressed-air system through our commercial and industrial grant program (see page 15) or our compressedair efficiency program below.

Compressed-air efficiency The U.S. Department of Energy reports that ten percent of a typical industrial facility’s electrical energy use is consumed by compressed-air systems. Industries with larger compressed-air loads or more rigorous treatment requirements may have as high as 30 percent of their energy consumption dedicated to compressed air. The compressed-air efficiency program provides incentives to customers for efficiency improvements in compressed-air systems and for completing compressed-air recommissioning studies that adhere to our company’s guidelines.

Other programs

Recommissioning and energy studies Recommissioning and Retrocomissioning, both commonly referred to as RCx, ensure that specific building systems perform interactively according to the design intent and the owner’s operational needs. Recommissioning ensures that a previously commissioned building is running at optimal performance. Retrocommissioning is a process that involves tuning up an existing building that never was commissioned after initial construction. Retrocommissioning identifies less-than-optimal performance in an existing facility’s HVAC equipment, lighting, and control and process systems and identifies cost-effective energy savings adjustments. The RCx study involves a six-month or longer process to gather data on energy-using systems in your building. Information gathered typically comes from control system trending data, equipment monitoring and data logging, and other sources.

Recommissioning/ Retrocommissioning (RCx) RCx is a six-month or longer process to gather data on energy-using systems in your building. The benefits include: ■■ A

rebate of 30 percent of the RCx study cost and $400 per kilowatt saved, up to $20,000, for eligible customers.

■■ Energy

cost savings of up to 20 percent.

RCx Lite RCx Lite is similar to traditional RCx programs but with lower study costs, a shorter timeline, and somewhat reduced energy savings. RCx Lite measures may include tuning set points, optimizing controls, and using low/no cost upgrades capable of achieving savings of 3 percent to 12 percent in most facilities. RCx Lite offers nearly all the benefits of traditional RCx studies, plus: ■■ Savings

of up to 75 percent of those achieved in a traditional, but more costly, RCx study–but often for as little as 25 percent of the cost.

■■ A

rebate of 50 percent of the cost of the RCx lite study up to a maximum
of $10,000.

■■ Buildings

must have 25,000 to 50,000 square feet of conditioned space to qualify.

Turnkey RCx Our Turnkey RCx study makes it easy
to identify energy-saving projects and ensure that upgrades are completed on time—so that savings begin right away. Customers may save up to 20 percent on their energy bills. When the Turnkey RCx study is complete, customers will receive an initial rebate
of 50 percent of the rebate study costs. When implementation is successfully completed, we’ll provide the remaining 50 percent of the Turnkey RCx study costs. Buildings must contain at least 50,000 square feet of conditioned space to qualify.

■■ A

more comfortable facility with fewer occupant complaints.

■■ Longer

equipment life. Lower energy bills.

■■ A

detailed building assessment completed by a qualified engineering professional.

Pre-approval of all RCx, RCx Lite, and Turnkey RCx applications is required to receive incentives.
