Delaware is a member of the Regional Greenhouse Gas Initiative (RGGI), a cap-and-trade program for reducing GHG emissions in North America that began its compliance period in 2009. Capping CO2 emissions from the power sector, the program aims to reduce emissions by 45% below 2005 levels by 2020 and additionally by 30% by 2030.

Delaware utilizes 65% of its RGGI proceeds on energy efficiency activities, administered through the Delaware Sustainable Energy Utility. 10% of proceeds is dedicated to the Delaware Weatherization Program for weatherizing low- and moderate-income homes. 5% is returned directly to ratepayers through the Low Income Heating and Energy Assistance Program. 10% is dedicated to other programs that reduce greenhouse gas emissions, and 10% is used for administration and policy development efforts. In 2019, Delaware received $14,071,271 in RGGI auction proceeds.

Total investments can be found in RGGI annual proceed reports, in the Delaware chapter. The latest available data is for calendar year 2017. During calendar year 2017, $27M of RGGI funds were invested. 78% of these funds were invested in energy efficiency projects; 9% were invested in clean and renewable energy projects. The remainder was invested in greenhouse gas abatement projects, direct bill assistance, and program administration.

Delaware is also a participant in the Transportation and Climate Initiative’s (TCI) effort to develop a cap-and-invest program for transportation emissions. TCI comprises states from North Carolina to Maine who are engaged in modeling, outreach, and program development efforts for a policy that could be implemented by each state and coordinated regionally to cap emissions from transportation and utilize proceeds from allowance auctions for clean transportation investments. The states are targeting November 2020 for an announcement of the program design. States would, at that time, decide whether to implement the program.

Avoided GHG emissions are reported to RGGI Inc. for all programs funded by RGGI proceeds. Program Administrators for programs reported to the Delaware Energy Efficiency Advisory Council (EEAC) utilize the Mid-Atlantic TRM to calculate energy efficiency and demand resource savings, costs, and emission impacts of programs they offer. In keeping with the state's EM&V regulations, Program Administrators file reports with the EEAC reporting energy impact information for each program; this data is used to calculate avoided greenhouse gas emissions achieved through the programs.

Public Building Requirements List All

In February 2010 Governor Markell issued Executive Order 18, which set a variety of energy conservation goals and requirements intended to make the state a leader by example in clean energy and sustainability.

Under Executive Order No. 18 (EO 18), executive branch State agencies and departments in State-owned or State-leased buildings were directed to achieve an overall collective reduction of 30%, subject to funding opportunities and constraints, by the end of Fiscal Year (FY) 2015 when compared to FY 2008. The order further prescribed a series of energy conservation practices for state employees to follow, such as turning off lights when they are not in use, eliminating the use of portable appliances, following green computing practices, and maintaining appropriate thermostat settings. The order also directed new construction and major renovation projects to be designed to meet or exceed the USGBC LEED Silver rating standards, and certification must be pursued for such projects if it can be accomplished at a reasonable cost. EO 18 also directs executive agencies and departments to procure at least 30% of their electricity load from clean, renewable sources.

As an extension of the State's efforts to track energy use in public buildings, Delaware joined the Better Buildings Challenge (BBC) in 2012. The BBC is a voluntary program administered by the U.S. Department of Energy, setting long range energy reduction goals for building portfolios and requiring partners to track and report detailed energy use annually. The BBC also requires partners to submit at least one showcase project to demonstrate best practices in energy efficiency and energy conservation, as well as develop and follow an implementation model that serves as a playbook to achieve energy use goals, identify barriers, and implement replicable solutions. The State currently tracks executive branch State buildings over 1,500 square feet using EPA's Portfolio Manager tracking database, or over 8 million square feet of state owned public building space. This achievement marked the State's successful completion of all BBC requirements, and as a result, Delaware was recognized by the U.S. Department of Energy as a BBC goal achiever. The State continues to participate in the BBC, and is being recognized for energy reporting for the 6th year in a row.

Fleets List All

Executive Order 18 sets goals for vehicles operated by state agencies to reduce petroleum consumption by 25%, vehicle emissions by 25%, and vehicle miles traveled by 15% by the end of fiscal year 2012 (using 2008 as the baseline year). In conjunction to these efficiency goals, the Governor requested that the size of the fleet be reduced by 20% from 2008 levels. Using data, Fleet Services was able to cut 22.6% or 579 vehicles. As of 2012, the amount of miles driven in Fleet vehicles was reduced by 21.62% and fuel use reduced by 11.22%. This saved 5,851,660 pounds of CO2 pollution into the atmosphere. One of the key components of EO 18 was to green Delaware's fleet and to enhance compliance with the Clean Air Act and Energy Policy Act.

All new light-duty vehicles state agencies, departments, and offices purchase must be hybrid electric, alternative fuel, fuel-efficient, or low emission vehicles, unless such a purchase compromises health, safety, or law enforcement needs. The State of Delaware Fleet Services purchased 10 Prius Prime vehicles as well as 3 Ford Focus Electric vehicles to add to the State Fleet Pool. Delaware State Fleet Services has committed to replacing 20% of the state fleet with EVs and PHEVs by 2025, totaling over 550 vehicles. The state has also negotiated multiple leases for rented state office space to include charging stations on-site for fleet vehicles. The Divsion of Climate, Coastal, & Energy is also funding a fleet charging project that will install charging stations at state-owned buildings across the state. This project will be complete by the end of 2020. The Delaware Department of Transportation also purchased two Ford Focus Electric vehicles and 16 Electric Transit buses, and plans to have 20 operating by 2021. Thanks to a new $2.6 million grant, these buses will be used throughout Delaware.

Energy Savings Performance Contracting List All

Title 29, Subchapter V, The Energy Performance Contracting Act encourages that agency facilities need to explore investments in energy conversation measures to ensure that there is immediate and long-term savings for facilities. These energy conservation measures include but are not limited to improving insulation, energy recovery systems, cogeneration systems, renewable energy systems, increasing the efficiency of lighting systems, and HVAC replacements. Title 29, Section 6973 authorizes an agency to enter into an energy performance contract with a qualified provider to reduce and evaluate operational costs of a facility. These providers develop a financial grade energy audit, which is combined into the final performance contract. The energy consumption and cost-savings attributed to energy savings measures must be reported on no less than annually and provide a report to the governmental unit. The Delaware Sustainable Energy Utility is now accepting applications for School Districts and State Agencies to enter into Energy Savings Performance Contracts through a tax exempt bond issuance. The DE SEU's Performance Contracting Program uses long-term utility cost savings from implementation of projects to fund the improvements performed by Energy Services Companies. Entering into the Energy Savings Performance Contracts will give participants access to technical advisors, financial and legal advisors, education, and training services.

Several activities took place in 2018. The Colonial School District completed a $7.6 million for energy efficiency and renewable energy capital improvements in sixteen buildings through an ESPC that was funded by bridge loan from the Delaware Sustainable Energy Utility (DESEU). It is slated for permanent financing from a DESEU Energy Efficiency Bond Issue in early 2019. These improvements are projected to yield $9.8 million in savings over 20 years with a net savings of $626,866.

The Delaware Division of Health and Social Services entered into and started construction on $3.7 million ESPC for energy efficiency improvements for 8 buildings that was funded by a bridge loan from the Delaware Sustainable Energy Utility (DESEU). It is slated for permanent financing from a DESEU Energy Efficiency Bond Issue in early 2019. These improvements are projected to yield $7.3 million in savings over 20 years with net savings $712,268.

The Indian River School District entered into and started construction on $8.2 million ESPC for energy efficiency improvements for 13 school buildings that was funded by a bridge loan from the Delaware Sustainable Energy Utility (DESEU). It is slated for permanent financing from a DESEU Energy Efficiency Bond Issue in early 2019. These improvements are project to yield $13 million in savings over 20 years with net savings of $1,222,924.

Utilities Summary List All

/Delaware has made advances toward strengthening its energy efficiency programs, establishing the nonprofit Delaware Sustainable Energy Utility (SEU) to operate programs to deliver comprehensive end-user efficiency and customer-sited renewable energy services. SEU operates as “Energize Delaware.” Since 2006, Delaware law has required electricity providers to engage in integrated resource planning (IRP). In 2009, Delaware approved an Energy Efficiency Resource Standard (EERS) that set goals for consumption and peak demand for electricity and natural gas utilities. The goals are 15% electricity consumption and peak demand savings and 10% natural gas consumption savings by 2015. However, rules outlining how these goals are to be met are still pending.

In 2014, the state legislature passed SB 150, an amendment calling for expansion of cost-effective electric and natural gas utility programs and allowing utilities to deliver these programs and recover costs through rates. SB 150 created the Energy Efficiency Advisory Council (EEAC), which established voluntary energy savings targets (electric and gas), similar to the EERS. The incremental energy efficiency targets are incremental annual savings as a percent of forecasted sales.

2016/2017 targets:  0.4% electric, 0.2% natural gas

2018 targets: 0.7% electric, 0.3% natural gas

2019 targets: 1.0% electric, 0.5% natural gas

The most recent budgets for energy efficiency programs and electricity and natural gas savings can be found in the State Spending and Savings Tables.

Customer Energy Efficiency Programs List All

In 2007, Senate Bill 18, Substitute Number 1 was passed, creating the nonprofit corporation Sustainable Energy Utility under the direction of an oversight board and the state energy coordinator within the Department of Natural Resources and Environmental Control (DNREC). The SEU was designed to operate programs to deliver comprehensive end-user energy efficiency and customer sited renewable energy services. In January 2013, the SEU re-launched a residential new construction program and has additional programs under development.

Parallel with the development of the sustainable energy utility, electric utilities are required to prepare integrated resource planning demand-side management plans. Delmarva Power & Light filed its second Integrated Resource Plan (IRP) on December 7, 2012, opened under Order No. 8259. On July 29, 2011, Delmarva Power & Light filed an application with the Commission seeking approval of the Company's proposed Residential Direct Load Control Program (PSC Docket No. 11-330). Delmarva Power & Light's New Residential Air Conditioning Cycling Program was approved on October 17, 2012.

The Sustainable Energy Utility (SEU) programs are funded by Regional Greenhouse Gas Initiative proceeds and via "special purpose" bonding by the State of Delaware. Revenue sources to pay off the bond debt and help the SEU to grow will include:

  1. Shared savings agreements with program participants,
  2. Partial proceeds from the sale of renewable energy credits in local and regional markets, and
  3. Green energy fund monies (from a fund, established by an earlier statute that collects revenue from electricity sales).


In 2014, the state legislature passed SB 150, an amendment calling for expansion of cost-effective electric and natural gas utility programs and allowing utilities to deliver these programs and recover costs through rates. The Energy Efficiency Advisory Council (EEAC) was created through SB 150. The Council began meeting in December 2014 to develop a suite of cost-effective energy efficiency programs and have since approved energy savings targets. Program implementation plans are also being developed through the Council and evaluation, measurement, and verification regulations to govern the programs are being drafted by DNREC.

Additionally, the EEAC has begun reviewing energy efficiency program portfolios developed by Delaware's energy providers and the Sustainable Energy Utility. In order to support a robust and comprehensive portfolio of programs, the EEAC worked to create a common template for all Program Administrators (PAs) to use when developing their program plans, budgets, and timelines to submit to the EEAC. This enables interested parties to better understand individual's plans and affords the opportunity to identify gaps that could be filled in either target markets and/or geographic coverage, while making it easier to identify where PAs could leverage and coordinate efforts to maximize cost-efficiencies and depth of services.

Energy Efficiency as a Resource List All

In 2009, Senate Bill 106 stated that energy efficiency would be the “highest-priority resource” in the state. Cost-effectiveness was one motivation for this decision. The Electric Utility Retail Customer Supply Act of 2006 requires electricity providers to file 10-year integrated resource plans that will address long-term supply contracts, including provisions for renewable energy and demand-side resources (26 Del. C. §1001-1012). Additional integrated resource planning rules are under consideration. In PSC Regulation Docket Number 60, the PSC entered Order Number 7318 (2007), proposing integrated resource planning regulation. This regulation was finalized in 2008.

Energy Efficiency Resource Standards List All

Summary: Delaware does not have a mandatory EERS. However, energy savings targets have been set by the Energy Efficiency Advisory Council (EEAC) and affected energy providers are currently working to meet these goals.

Established by SB 150, House Amendment 2 in 2014, the Delaware Energy Efficiency Advisory Council convened to establish guidance on cost-effective energy efficiency programs. The Delaware Energy Efficiency Advisory Council (EEAC) provides guidance to energy providers in developing energy efficiency, energy conservation, peak demand reduction, and emission-reducing fuel switching programs for all customer classes. The EEAC collaborates with the Public Service Commission (PSC) and Public Advocate (PA) to guide energy providers in establishing 3-year program  portfolios that must be approved by the PSC or other appropriate regulatory body.

The Act set up an eleven-member stakeholder workgroup to assist in developing key regulations, assessing the feasibility and impact of pursuing the established targets, reviewing progress annually, and recommending changes to the plan as needed. In its June 2011 report, the workgroup identified several issues that undercut the effectiveness of the policy. First, the level of proposed funding (gathered through an energy efficiency charge on customer bills) made it unlikely that the state would meet the targets established in the Energy Efficiency Resource Standards Act. Second, the workgroup found that conflicting state statutes muddied the institutional structure around efficiency program implementation and accountability, making it impossible to determine which entity (utilities, the Sustainable Energy Utility, or the Public Service Commission) has accountability for EERS performance results and the development of enforcement mechanisms.  

Given the lack of final implementation rules, and the funding and institutional challenges outlined above, Delaware's energy savings targets are considered voluntary.

Established by SB 150, House Amendment 2 in 2014, the EEAC convened to establish guidance on cost-effective energy efficiency programs. The EEAC has established voluntary energy savings targets (electric and gas), similar to the EERS. Utilities and program administrators are encouraged through the EEAC to develop and implement energy efficiency programs that will yield a reduction in electric and natural gas usage. Programs plans are designed around a 3-year timeframe but have the ability to be updated annually, with annual targets increasing each year to reach the cumulative 3-year goal. The incremental energy efficiency targets are incremental annual savings as a percent of forecasted sales: (2016/2017) E – 0.4% G – 0.2%; (2018) E – 0.7% G – 0.3%; (2019) E – 1.0% G – 0.5%.

The state evaluates the issue of decoupling on a utility-by-utility basis when it sets utility rates through rate case proceedings. In September 2009, the PSC entered Order 7641 (Docket No. 09-276T), examining a modified fixed variable rate design for Delmarva Power (electric and gas). The docket has been on hold since late 2011 because the conditions required to implement decoupling could not be met until Delmarva Power was able to implement energy efficiency programs that benefit its customers. In 2014, the state legislature passed SB 150, calling for the expansion of cost-effective electric and natural gas utility programs and allowing utilities to deliver these programs and recover costs through rates.

Delmarva Power and Light’s program plan filed with the PSC did not include provisions for a performance incentive. Delmarva proposed to recover the costs of the program, amortized over a five-year period, using the same rate of return as their supply-side capital investments.

Evaluation, Measurement, & Verification List All
  • Primary cost-effectiveness test(s) used: total resource cost test  

  • Secondary cost-effectiveness test(s) used: rate and bill impacts  

The evaluation of ratepayer-funded energy efficiency programs in Delaware relies on legislative mandates (Energy Efficiency Resource Standards Act of 2009). The Delaware Department of Natural Resources and Environmental Control administers evaluations. Statewide evaluations are conducted.  

According to the Database of State Efficiency Screening Practices (DSESP), Delaware relies on the Total Resource Cost Test (TRC) and considers it to be its primary cost-effectiveness test. Delaware’s TRC accounts for avoided environmental compliance costs, reduced emissions, and improved participant health. Delaware also accounts for other non-energy benefits of productivity (avoided O&M costs), non-primary fuel benefits, and water savings. Rules for benefit-cost tests and evaluation requirements are outlined in the Delaware Evaluation Framework. Evaluation, Measurement, & Verification Regulations (Title 29, Section 8059) were published in the State Register of Regulation December 2016, becoming promulgated January 11, 2017.   

These regulations include EM&V procedures and standards including impact evaluation, environmental outcomes, process evaluation, market effects, and cost-effectiveness evaluation. They require energy providers to actively demonstrate, document, and report compliance with energy savings targets. The EM&V regulations also define how to measure electricity and natural gas savings.  

The EM&V Subcommittee to the Energy Efficiency Advisory Council (EEAC) was formed to help guide the council on all aspects of EM&V, ensuring compliance of EM&V activities with the regulations, and striving for consistency in the execution of EM&V activities statewide.  

Further information on cost-effectiveness screening practices for Delaware is available in the Database of State Efficiency Screening Practices (DSESP), a resource of the National Efficiency Screening Project (NESP).

Guidelines for Low-Income Energy Efficiency Programs List All

Requirements for State and Utility Support of Low-Income Energy Efficiency Programs

Delaware established legislative energy savings targets in 2009 with the adoption of SB 106, although these have yet to be implemented. The legislation sets up a Sustainable Energy Trust Fund to collect charges assessed by energy providers in service of energy savings goals. SB 106 specifies that 20% of assessment be provided to the Weatherization Assistance Program.

Electric utility restructuring legislation passed in 1999 specifies that Delmarva Power and Light collect 0.095 mills/kWh (approximately $800,000 annually) from customers to be forwarded to the Department of Health and Social Services, Division of State Service Centers, to be used to fund low-income fuel assistance and weatherization programs.

The Delaware Weatherization Assistance Program has an annual goal of completing 400 homes.   In addition, to make low-income energy efficiency programs more accessible, a Guidance Document was drafted in 2016 as part of the merger settlements approved by the PSC between Exelon and Delmarva Power and Light to allocate $4,000,000 of the funds towards low-income customer energy efficiency programs. This Guidance Document applies to DPL customers, and funds are available to support organizations delivering energy efficiency programs to low-income rate payers. Organizations that receive grants to run low-income energy efficiency programs will increase energy efficiency measures for low-income Delaware households, increase statewide electric and gas savings, engage and inform low-income households about the benefits of energy efficiency, develop a community-based approach to address energy efficiency issues in low-income housing by mobilizing public and private sector resources, and ensure the greatest extent feasible that job training, employment, and contracting generated by this grant will be directed to low-income households. All settlement-funded low-income programs must be officially recommended by the EEAC and approved by the PSC. The Delaware Public Service Commission approved Delmarva Power's low-income settlement distribution plan at a hearing on May 22, 2018.  The RFP for the money manager was issued and should be selected in May 2019.  Funds will be disbursed in the next 2-3 years.

Cost-Effectiveness Rules for Low-Income Energy Efficiency Programs

In 2016, the Evaluation, Verification, & Measurement subcommittee of the EEAC reviewed net-to-gross ratios, avoided costs, and net environmental impacts for low-income energy customers. The EM&V Committee recommended a proposed net-to-gross ratio for low-income programs to be 1. This includes income-eligible HES, low-income multi-family, and low-income new construction programs.

The EM&V Committee in 2016 recommended specific non-energy benefits for low-income programs. These non-energy benefits include weatherization reduced arrearages and participant health and safety benefits. Specific values were also applied to non-energy benefits and are locked in for three years. These non-energy benefits were unanimously recognized and approved by the EEAC.

Coordination of Ratepayer-Funded Low-Income Programs with WAP Services

The Department of Natural Resources and Environmental Control (DNREC) administers federal weatherization funds, which are coordinated and joined with federal LIHEAP block grant, state utility funds, and funds from the Regional Greenhouse Gas Initiative (RGGI).

The Low-Income Energy Efficiency Committee of the EEAC began meeting in 2016 with a purpose to develop cost-effective low-income programs to submit before the EEAC. It is made up of stakeholders from the EEAC, utility representatives, state agencies, community action agencies, community-based organizations, faith-based organizations, and community foundations. In an effort to better serve the low-income population in the state, the committee was tasked with identifying existing services that provide funding for affordable housing. Some of the existing programs identified include the Weatherization Assistance Program (WAP), Low-Income Home Energy Assistance Program (LIHEAP), SHARING Fund, Beat the Peak, and Assisted Home Performance with Energy Star.

The Weatherization Assistance Program (WAP), Low-Income Home Energy Assistance Program (LIHEAP), and Delaware Sustainable Energy Utility collaborate in order to deliver services to as many clients as possible.  The Delaware Pre-Weatherization Program (Pre-WAP) is a unique initiative developed in order to serve clients that would otherwise be deferred by WAP due to the condition of the client’s home.  The Pre-Weatherization program helps low-income families in Delaware prepare their homes to meet the requirements for the State of Delaware’s Weatherization Assistance Program.  Many potential Weatherization Assistance Program (WAP) clients cannot afford the structural home repairs needed to qualify the home, and therefore lose the ability to participate in weatherization assistance.  Participants whose properties have been deferred by WAP for structural reasons are referred to Energize Delaware’s Pre-Weatherization Program.  Energize Delaware provides funding to pay for the repair of the structural issues, such as leaky roofs, broken windows and doors, or moisture in crawl spaces.  The Pre-Weatherization Assistance Program will inspect homes, hire contractors, schedule repair work, and perform a quality assurance post-inspection, then re-admit these units into the Weatherization Assistance Program.  Over 200 homes have been completed to date at an average cost of $3,000 per home.  Participants in the LIHEAP are also referred to WAP for additional services.
