Taking Care of Business

Reduce your costs with efficient lighting Lighting accounts for 17 percent of electricity consumed annually in the United States, with another 4 to 5 percent used to remove waste heat generated by inefficient lighting fixtures.

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.

Guidelines ■ Rebates

for retrofits from T12 fluorescent lighting systems to standard-efficiency T8 fluorescent lighting systems no longer are available. An incentive for retrofits from T12 fluorescent to low-watt T8 (28 watts per lamp or less) fluorescent lighting systems is available.

■ Otter

Tail Power Company reserves the right to inspect and verify installations before issuing rebates.

■ Rebates

also are available for lighting controls.

By automatically controlling lights based on occupancy or natural light levels, lighting controls can cut lighting energy costs as much as 50 percent.

Eligible retrofits include light-emitting diode (LED) fixtures and lamps, high-efficiency fluorescent systems, and occupancy and daylighting based lighting controls.

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

in an area and manner that will prevent breakage.

■ Post notices to show employees where and how to store lamps.

■ If storage on-site isn’t possible, transport the lamps to a storage location. A hazardous waste manifest isn’t 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.

CIP rebates will not exceed 75 percent of installed costs. Funding limits and other program guidelines and limitations apply.

Drive Power

Drive Power Efficient electric motors The U.S. Energy Information Administration (EIA) reports that nearly half of the electricity consumed in the manufacturing sector is used for powering motors that drive fans, pumps, conveyors, and compressors. At the same time, electricity costs make up about 96 percent of the total life cycle cost of a motor, while capital costs and maintenance expenses account for 3 percent and 1 percent respectively.

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 energy-efficiency regulation 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 levels to qualify for incentives for new motors and replacement of non-operating 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.

Taking Care of Business

High rebate, permanent savings Our motor rebate program offers up to $7,000 for each qualifying energy-efficient motor installation. Rebates are available for qualifying open drip-proof, totally enclosed fan cooled, and explosion-proof motors.

But your savings don’t end with a 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 horsepower 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 Rebates will not exceed 75 percent of project costs or 75 percent of customer’s annual electric bill.

To qualify for rebates, all motors must meet efficiency requirements as listed on the following pages.

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.

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 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.

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

Drive Power

Adjustable-speed drives ■ Rebate

of $60 per horsepower for process and other nonseasonal centrifugal applications.

■ Rebate

■ Rebates

will not exceed 75 percent of installed ASD cost.

■ Rebates

will not exceed 75 percent of your annual electric bill.

■ System

designer or installing contractor must ensure the entire facility complies with the IEEE Standard 519 after completion of the ASD installation or retrofit. Failure to comply with this rule in ASD installations may result in disqualification of any rebate request.

CIP rebates will not exceed 75 percent of installed costs or 75 percent of customer’s annual electric bill. Funding limits and other program guidelines and limitations apply.

Taking Care of Business

A cool deal to raise profits 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 energy 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.

Energy-efficient refrigeration

3. Display cases and walk-ins.

4. Preventive maintenance and cleaning measures.

The amount of your rebate and 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.

Heat pumps

Heat pumps Air-source, cold-climate, and geothermal heat pumps provide heating and cooling No matter the temperature, heat is always available in the air around us and in the ground.

Heat pumps take advantage of that by moving heat in or out of buildings to keep spaces comfortable.

Because they move heat rather than produce it, heat pumps operate with high efficiency.

Rebates are available for air source, cold-climate, and geothermal heat pump installations.

Requirements vary by heat pump configuration,

program, and state policy. Below is a summary table of rebates per ton for qualified systems and the rating and rate requirements that apply.

Energy control rebates are available for qualified off-peak installations.

CIP efficiency rebates are available for heat pump systems that meet required efficiency levels— regardless of the rate on which it’s served.

Here’s how it works

Commercial and industrial grants

Commercial and industrial grants

■ You

submit your energy-efficiency proposals using one of our grant proposal forms. Your Otter Tail Power Company Industrial Services Engineer or Energy Management Representative can help.

■ We

evaluate your proposals to determine the effect of the improvements suggested.

■ If

the evaluation indicates that sufficient energy savings will result, we’ll let you know how much grant money you can expect from us to implement your energy-saving measures. Our analysis will include both the amount of the up-front grant and the estimated long-term savings.

■ You

decide if the cash grant and long-term savings are attractive enough to proceed with your improvements.

■ If

you decide to proceed, you’ll receive a check for the approved amount when the installations are complete.

Guidelines

Measurement and verification Rules from the Minnesota Department of Energy Resources apply on measurement and verification of energy savings for large grant projects. If you anticipate energy savings of 1,000,000 kWh or more annually, consult your Industrial Services Engineer or Energy Management Representative to let us help ensure that you qualify for commercial and industrial grant program incentives.

■ Energy-saving

measures must be installed within six months of project approval unless special arrangements are made.

■ We

reserve the right to inspect and verify project location and installation before issuing the grant check and to verify installation and actual energy savings after project completion.

■ Incentives

for grant projects may be capped.

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 compressed-air energy delivered to the building’s air system.

Identify ways to make your system more efficient and cost effective. This program provides incentives of 50 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.

16

Taking Care of Business

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 10 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.

Measure

Incentive

No-loss drains

$150/drain (up to 50 percent of project cost)

Efficient compressors <50 HP

$200/HP

Leak studies and repairs (>50 HP)

50 percent of study cost (up to $3,000)

Flow controllers

$2,500 per controller (up to 50 percent of project cost)

Compressed air recommissioning study

100 percent of cost (up to $10,000)

Specific program rules and requirements apply. Applicants must use a compressed-air recommissioning study provider we’ve preapproved to be eligible for 100 percent study cost incentive.

Contact your Otter Tail Power Company Energy Management Representative or Industrial Services Engineer before proceeding with any compressed-air improvements to ensure eligibility for program incentives.

Recommissioning and retrocommissioning, both commonly referred to as RCx, are processes that ensure 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 involves tuning up an existing building that never was commissioned formally after construction. The retrocommissioning process identifies less-than-optimal performance in an existing facility’s HVAC systems and identifies cost-effective energy-saving adjustments.

Four levels of program services are offered.

Traditional RCx Traditional RCx involves an extensive process of gathering 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.

■ Potential

energy cost savings of up to 20 percent.

■ A

more comfortable facility with fewer occupant complaints.

■ Longer

equipment life. Lower energy bills.

■ A

detailed building assessment completed by a qualified engineering professional.

Buildings must contain at least 50,000 square feet of conditioned space to qualify.

Turnkey RCx

Buildings must contain at least 50,000 square feet of conditioned space to qualify.

RCx Lite

Other programs

Recommissioning energy studies

RCx Lite is similar to traditional RCx programs but with lower study costs, a shorter timeline, and somewhat reduced energy savings requirements.

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 Lite A fast-track, low risk program to help building owners capture energy savings from their existing building equipment and its operation. Typically customers can cut 5 to 10 percent of their energy cost by participating.

■ A

rebate of up to $9,500 per participant that can cover 100 percent of the program cost.

■ To

be eligible, buildings must have a digital control of their building’s HVAC equipment via a building automation system (BAS).

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

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.

Contact your Energy Management Representative or Industrial Services Engineer early in the development of your project to learn more about these programs.
