Integrated Resource Plan Underway

At the September 17th Public Utilities Committee meeting, CWLP presented an update on its Integrated Resource Plan (IRP), which will identify what type and mix of generation will be best suited to provide reliable and reasonably priced electrical power to meet the community’s needs for the next 20 years. At the meeting the utility provided an overview of public comments received and how they were considered in the IRP.

The IRP is compiling and analyzing economic data of CWLP’s existing electric resources along with the economic data of other options such as wind, solar, natural gas combustion turbine, smaller reciprocating engines, power purchases from the market, demand side management and energy storage. At the end of the IRP process, the Springfield City Council will be presented with a number of different energy portfolios scenarios, including plant retirements of any or all Dallman units and various generation mixes, along with the projected costs and risks of each. An open house to display the results of the IRP and allow for public comment in the spring of 2019 is being planned.

To learn more about the IRP, see CWLP’s recent presentation given at the September 17th meeting here and or watch the full meeting video here.

Heat Pumps Can Help Customers Save

Installing a new high-efficiency heat pump can save you money and earn you a rebate on your CWLP electric bill.

In addition, customers who install heat pumps as their primary1 heating source are eligible for the utility's Electric Heat Rate, which provides a 9% savings over CWLP's regular residential electric rate from September 16 through May 15. NOTE: Customers who are currently on CWLP's Electric Rates 34-37 already receive this savings.

The Heat Pump Rebate is available to CWLP electric customers who install qualifying air-source or geothermal heat pumps in their new or existing residential or commercial properties. (Any structure that is not owner-occupied, including apartment complexes, retirement facilities and office buildings, is considered a commercial property for purposes of this rebate program. For commercial heat pump rebates, pre-approval from CWLP prior to system installation is required.
Heat Pump Rebate Announcement

The amount of your rebate depends on whether or not your heat pump is an air-source or geothermal system. For an Air-Source System, your rebate will be $300 per ton of installed cooling capacity. For a Geothermal System your rebate will be $500 per ton of installed cooling capacity.Rebates are granted on a first-come, first-served basis while funding lasts. All rebates under $1,000 will be provided as bill credits. For rebates of $1,000 or higher, customers may opt to receive their rebate in check form by marking the appropriate box on the rebate application and providing their social security number or, in the case of commercial applicants, a W-9 form. Checks are available only for rebate amounts of $1,000 or more.

All equipment model numbers will be verified through the Air Conditioning, Heating and Refrigeration Institute (AHRI) Directory of Certified Unitary Equipment. In addition, CWLP reserves the right to make on-site inspections of heat pump installations before granting rebates. To receive a Heat Pump Rebate, residential customers must complete and return a Heat Pump Rebate Application to CWLP within one year of the heat pump's installation date.

To qualify for the Heat Pump Rebate program, commercial customers must apply for pre-approval from CWLP prior to installing their heat pump system.

Gaining Pre-approval for a Commercial Heat Pump Rebate

  • CWLP will determine if your heat pump qualifies as your "primary heating system" using a formula that factors your building's square footage and the heat pump's heating capacity.
  • New commercial water loop systems will be considered for rebate eligibility on a case-by-case basis. Contact the Energy Services Office at 217.789.2070 or by email at for more information.
  • British thermal units (BTUs) per hour. Each "ton" of cooling capacity built into a heat pump or air conditioner equals 12 kBTU per hour (12,000 BTU/h). Residential central cooling systems typically range in size from two to four tons of cooling capacity (24 to 48 kBTUh).

Once you are pre-approved for the rebate you can continue the application process. To apply for your residential heat pump rebate, following installation complete and sign a Residential Heat Pump Rebate Application, have your contractor sign it, and submit it—along with a detailed sales receipt that includes equipment model numbers and the total project cost—to CWLP within one year of the installation date.

CWLP Energy experts ready to help customers with efficiency & savings

Home energy audits and technical assistance programs helping people save.

City Water, Light and Power Energy Experts are in the business of helping Springfield residents and commercial customers save money and energy through the utility’s various technical assistance programs. The CWLP Energy Experts offer a Money-Back Home Energy Audit program to help residential electric customers reduce their energy usage, save money, address drafts, or just to help them figure out what to do to make their home more efficient. In addition, the Energy Experts can also provide residents and businesses on-site assistance and conduct individual account assessments to help identify efficiency issues or usage questions.

CWLP's home energy audit, which is covered by a one-time $25 fee added to a customer’s electric bill, is available to anyone owning or residing in a residential property that receives metered electric service from CWLP. The audit take about two hours to complete in most homes and involves a search for inefficiencies in the home from the attic to the basement, a blower door test and a thorough assessment detailing any problems.

After the audit is complete, the Energy Expert will provide the customer with a packet of efficiency products selected based on the needs identified by the audit. In addition to reviewing findings with the customer as the audit and blower door test are in progress, the Energy Expert will write a report that details all of the improvement recommendations, share information on available rebates and provide savings estimates achievable from each. If any or all of the improvements listed in the audit report are made within one year of the initial audit and the customer completes a follow-up audit, a $25 rebate will be issued to the customer.

The CWLP Energy Services Office offers “Smart Solutions,” home efficiency workshops throughout the year at the Lincoln Library and on-demand in a group setting for organizations or neighborhood groups, who have a minimum of 15 attendees. In most cases, the workshops can be set up at the convenience of the requesting organization.

CWLP offers free facility technical assistance to commercial electric customers upon request. Included in a commercial facility technical assistance is a walk-through evaluation of the business' energy systems, including lighting, HVAC and thermostat operation, water heating and other specialized equipment or systems. During the walk-through, the Energy Expert also addresses specific concerns and can provide tips on equipment or operational changes that could be made to reduce energy usage, as well as information about rebates, grants and other incentives for improving energy or water efficiency that might be available from CWLP and other sources.

CWLP Energy Experts also can provide the customer with billing histories in both table and graphical form and explain the bill components. Comparisons of weather-related data can also be provided, allowing the customer to understand the impact weather can and has had on consumption.

The general Technical Assistance (TA) program offered by CWLP is designed to help customers who are experiencing efficiency-related problems in their homes or businesses or who have any type of energy efficiency question. TAs, which are free of charge to CWLP electric customers, can be conducted on-site, over the phone, by mail, or by email—depending on the circumstances and needs of the customer.

Some TAs are investigatory in nature, such as those provided to customers who call with high-bill concerns. Some are educational in nature, such as those that teach customers how to use automatic setback thermostats and provide advice about various efficiency tools, choosing a heating and cooling contractor, or making economic comparisons of energy systems. The CWLP Energy Experts can even help customers design energy efficiency into the structure before building a new home or business.

To make an appointment or for more information on the CWLP Money Back Home Energy Audit or any of the technical assistance programs, customers can call the CWLP Energy Services Office at 789-2070 or email
