DEEP: Siting Clean Energy on Brownfields

Siting Clean Energy on Connecticut Brownfields
There are many resources that are useful in siting a clean energy facility in Connecticut on previously used land, sometimes called a brownfield if the land has been or is perceived to be polluted and is now underused.  Below you will find links to information on financing and incentives, guidance, potential locations, and liability limitations for both clean energy projects and brownfield reuse.

Municipalities Seeking Renewable Energy Developers for Landfill Sites
The following municipalities (or private parties) control closed landfill sites and are seeking to develop renewable energy on these properties.  This list is updated periodically.
Please contact DEEP Brownfields Coordinator Mark Lewis at if you would like to be added to this list.
Financing and Incentives
State and Federal Government Funding may be available for clean and energy efficiency projects developed on contaminated sites. Funding (grants and loans) and in some cases, local tax incentives are available for site assessment, cleanup, and redevelopment or reuse projects with clean energy and energy efficiency components.
State Renewable Energy Incentives
The State of Connecticut offers a wide array of renewable energy programs and incentives:
Combined Heat and Power (CHP)
An efficient, clean and reliable way to generate electricity and heat from a single fuel source, such as commercially available gas turbines, microturbines, reciprocating engines, steam turbines and fuel cells.
Connecticut Property Assessed Clean Energy (C-PACE)
Financing is available to eligible property owners for energy efficiency retrofits, clean energy improvements, and smart energy upgrades through placing a voluntary assessment on their property tax bill.
Low and Zero Emissions Renewable Energy Credits (LREC/ZREC)
Renewable generation can now be developed through Class I renewable energy credits (RECs) under 15-year contracts with owners or developers of renewable energy projects in Connecticut.
Class I and Large-Scale Hydropower Procurement
In February of 2015, DEEP issued a  draft Request for Proposal (RFP) in which private developers can submit proposals to enter into power purchase agreements (PPAs) for energy and environmental attributes with Eversource and UI for large scale hydropower (up to 15 years) or Class 1 renewable energy sources (up to 20 years).  This draft RFP was issued jointly with Massachusetts and Rhode Island, with each state having different criteria and legal requirements.
Net Metering and Virtual Net Metering
Connecticut requires electric utility companies to provide a billing credit to customers who produce power using on-site generation, through Net Metering and Virtual Net Metering. Eligibility requirements and compensation will vary with each program.
State Incentives for Brownfield Remediation and Development
Targeted Brownfield Development Loan Program offers low/flexible/deferred interest 20-year loans for environmental assessments, remediation, and other eligible costs for brownfield redevelopment.
Brownfield Tax Incremental Financing (TIF) can be used to help facilitate brownfield redevelopment projects through future sales or property taxes.
Federal Incentives for Brownfield Remediation and Development
U.S. EPA offers many incentives to eligible brownfield applicants, including grants and loans. (Availability of federal funding may vary by year.)  
 Brownfields Grant Funding:
  • Area-wide Planning Pilot Program
  • Brownfields Assessment Grants 
  • State-Wide Revolving Loan Fund 
  • Brownfield Cleanup Grants
  • Environmental Workforce Development and Job Training Grants
  • Multi-Purpose Pilot Grants
  • Training, Research, and Technical Assistance Grants
  • Targeted Brownfields Assessments
State Resources: Requirements and Technical Assistance
Connecticut Toolbox for Brownfield Remediation and Reuse
DEEP has developed several guidance documents to assist in evaluating Brownfields sites for redevelopment:
State Brownfields and Voluntary Remediation Programs provide environmental, financial, and technical assistance and incentives that promote brownfield cleanup and redevelopment.
Connecticut Closed Landfills
The list and map include information about landfills that could potentially be used for clean energy development.  (They are not intended to be exhaustive or an acknowledgement of ideal properties for renewable energy development.)
Please contact DEEP Brownfields Coordinator Mark Lewis at if you have questions about these documents or believe other sites should be included.
Federal Resources
Brownfield Road Map
The Brownfields Road Map is designed to help non-technical stakeholders understand options for site investigation and cleanup and communicate effectively with technical professionals.
Revitalizing Contaminated Sites: Addressing Federal Liability Questions
This U.S. EPA handbook is a compilation of enforcement tools, guidance, and policy documents that are available to help promote the cleanup and revitalization of contaminated sites.
U.S. EPA Re-Powering America’s Land
provides information on how contaminated lands, landfills, and mine sites can be reused as renewable energy installations and supplies best practices, tools and resources for screening properties for renewable energy potential.
EPA's RE-Powering America’s Land Electronic Decision Tree tool helps communities, local governments, site owners and other stakeholders explore the feasibility of solar or wind energy on formerly contaminated properties and underutilized sites.
Additional Information:
EPA Targeted Brownfields Assessment (TBA) Program assists municipalities and non-profits to minimize uncertainties of a contaminated site.
National Renewable Energy Laboratory (NREL) conducts numerous analyses for using Renewable Energy on contaminated lands.
Renewable Energy Potential for Brownfield Redevelopment Strategies provides information on renewable energy and processes to identify renewable energy technologies for Brownfields.
