Energy Efficiency Programs
“Energy efficiency programs produce 'negawatts' - power that is never used.”
Eversource is a Nationally Recognized Leader in Energy Efficiency
Eversource is consistently recognized as a leader in energy efficiency by national industry organizations. Two states within which Eversource operates have ranked in the top 10 of the American Council for an Energy-Efficient Economy (ACEEE) State Energy Efficiency Scorecard for the past eight years. In its 2014 State Scorecard, the ACEEE ranked Massachusetts as the number one state in energy efficiency for the fourth year in a row and Connecticut ranked sixth in the nation. ACEEE also ranked Boston the number one city in the nation. Eversource takes great pride in helping our states and communities remain vibrant and successful by administering programs that are emulated by others across the country.
Energy Efficiency Benefits Every Customer
Energy efficiency is an inherent part of our region's energy source mix and a critical component of our overall strategy for meeting the needs of our customers. The Eversource energy efficiency portfolio is designed to reflect and respond to the way our customers use energy today and takes a multi-year approach that enables us to plan for the future.
Energy efficiency is one of the most cost-effective ways to collectively save money, create jobs, reduce greenhouse gas emissions, enhance energy security, and reduce the need for additional generation plant construction. Through energy efficiency programs, energy is saved in thousands of homes and businesses and in effect produces “negawatts” - power that is never used. This energy savings is the equivalent of building a virtual power plant. In total, over the 2012-2014 period, energy efficiency peak demand savings by Eversource customers was approximately 350 megawatts (MW).
In addition, in 2014 the energy efficiency programs administered by Eversource resulted in an estimated $180.7 million savings for our customers. Last year alone:
- Eversource electric customers saved over one billion kilowatt hours (kWhs) of electricity and will save more than 11 billion kWhs over the lifetime of the installed measures. To put those two numbers into perspective, the electricity saved in 2014 through energy efficiency measures could provide power for all 3.1 million Eversource electric customers for seven days and the lifetime savings could power the same number of customers for 74 days.
- Eversource gas customers saved over 9.2 million therms (1 therm equals 100,000 British Thermal Units) and more than 131.7 million lifetime therms. The natural gas saved in 2014 through energy efficiency measures could provide energy for 500,000 Eversource natural gas customers for three days and the lifetime savings could provide energy to the same number of customers for 45 days.
- “Fuel neutral” initiatives administered by Eversource, such as programs which install weatherization and insulation measures, also saved customers an estimated 521,388 MMBTU (MMBTU is defined as 1 million British Thermal Units) from reductions in home heating fuel usage such as oil, liquid propane, kerosene and wood. The emissions reduced by not using these fuels equates to taking 5,820 passenger vehicles off the road.
Environmental benefits from the successful implementation of Eversource’s energy efficiency offerings from 2012 through 2014 resulted in cumulative peak demand MW reductions, generation equivalents and annual MWh savings as shown in the graphs below:

Empowering Customers with Energy Savings Plan
In 2014 Eversource empowered its customers to make smart energy decisions and improvements with the launch of the online tool, Energy Savings Plan. Energy Savings Plan is an interactive tool within Eversource.com that enables residential and business customers to examine how they are currently using energy, how they compare to other customers, and, most importantly, how they can reduce their energy consumption costs. Energy Savings Plan utilizes our customer’s existing usage data, collects additional information through a series of easy-to-answer profile questions, and then makes customized, actionable energy efficiency recommendations. Features of the online tool include potential savings estimates, “learn more” case studies and links to solution resources.
Energy Efficiency at Home
A 1963 suburban home was cold in the winter and hot in the summer. Eversource connected the homeowner to an authorized contractor for an in-home assessment, identifying energy-saving opportunities resulting in annual savings of more than $1,000.
“After completing the basic assessment, the technician explained that insufficient insulation in my attic was the main source of my heating and cooling inconsistencies. After explaining the benefits and cost savings of the upgrades, it became clear that the addition of insulation was a worthwhile investment for my family and my wallet.”
In 2014, residential customers took advantage of rebates and incentives that encourage the purchase of energy-efficient products such as lighting, insulation, heating, cooling, windows, and water heating equipment.
- Comprehensive Home Improvements: Eversource offers customers a wide array of services, incentives, and financing to enable energy savings in customer homes. In 2014,77,660 Eversource customers in all three states participated in our industry-leading home energy assessment and service programs that provide turnkey energy improvements and rebates.
- Customer Experience Enhancements: The Massachusetts Home Energy Services Program introduced an Energy Concierge pilot with the goal of increasing customer satisfaction and encouraging more customers to install energy-efficient products. Results of 1,000 served customers will be evaluated and key learnings will be applied to the broader program.
- High Efficiency Lighting: In 2014, retail lighting programs administered by Eversource increased the sale of light emitting diode (LED) bulbs in Connecticut by 175 percent, representing 38 percent of total residential lighting sales, compared to just 13.8 percent in 2013. Similarly, New Hampshire saw an increase in LED bulbs purchased, from just over 10 percent in 2013 to nearly 44 percent in 2014.
Energy Efficiency at Work
For two years, a steel manufacturer worked with Eversource on a series of projects to improve the factory’s energy efficiency. LED lighting, refrigeration controls, programmable thermostats, and more resulted in an annual savings of about $19,000.
“Improving our energy efficiency was a fairly large undertaking. Luckily, Eversource helped us identify ways we could simultaneously modernize and save on our energy costs. They made the overall process a smooth and timely one with no disruption to our employees or customer service.”
Eversource supports commercial and industrial customers by helping to identify smart energy improvements, lowering operational costs, and enabling greater business competitiveness. Eversource retains teams of highly skilled technical staff to help customers identify energy saving opportunities, and offers attractive financial incentives to help facilitate implementation.
- Dedicated energy efficiency account executives and consultants are available to business customers to advise and assist with efficiency opportunities. Customers benefit not only from cost reductions; these efforts also often result in enhancements to their business environment and/or productivity.
- In 2014, a new initiative for tenant fit-out spaces in Massachusetts encouraged customers to utilize comprehensive lighting solutions through attractive incentives for eligible projects. This simplified, flexible approach is critical in the fast-paced fit-out market and has been well received by large property management firms in our Eversource territory.
- The PRIME program provides manufacturers with a systematic approach to evaluating and identifying inefficiencies and waste in operations to streamline production and reduce electrical energy consumption and environmental impact. By utilizing LEAN manufacturing techniques manufacturers can reduce costs and remain competitive.
- Eversource remains focused on incentivizing LEDs to replace metal halide or high pressure sodium exterior lighting in parking lots and fluorescent lighting in buildings. Through the upstream lighting program, large commercial and industrial customers can purchase energy–saving compact fluorescent lights (CFLs) and LEDs at a discounted rate from participating distributors, eliminating the need for a paper rebate form.
Examples of Creative Leadership
Energy consumption is highly concentrated with our largest customers, with under four percent of our customers using over 75 percent of the energy we deliver. This provides Eversource the opportunity to engage these customers in a partnership (MOU Partnership Agreement) to significantly support and expedite energy efficiency efforts to reduce energy usage, carbon impacts, and operating costs. Eversource applies decades of experience driving energy efficiency results in all systems and technologies consuming electricity and natural gas.
- In 2010, Eversource signed a ground breaking Memorandum of Understanding (MOU) with the Massachusetts Institute of Technology (MIT). As part of this partnership, MIT committed to a 15 percent reduction in energy use over a three-year period. At the end of the term, MIT not only achieved but exceeded its goal. What is truly remarkable is that this was done while MIT was still in a growth mode. The graphic below illustrates how growth and energy use were decoupled through the efforts of this partnership.
- In 2014, Eversource and the University of Massachusetts-Amherst began a three-year energy efficiency alliance with a goal of reducing energy consumption on campus by three million kWhs per year. Eversource will provide assistance with energy efficiency incentive funding, technical expertise, outreach and educational programs on campus. In addition, we will be involved in the design of new construction, expansion and major renovations, with a target to be 25 percent more energy efficient than is state mandated.
- The strategy supporting this success has been scaled and replicated at a number of our largest customers across the Eversource territory in 2014. The value of the relationships is not only experienced in financial results, but also in the response from these customers in recognition and MOU Partnership Agreement extensions.
