Grid Scale Competitive Procurements

In order to continue making progress towards the state’s greenhouse gas emissions reduction targets, diversify fuel sources, and improve electric reliability, DEEP has conducted procurements for grid-scale renewable and zero carbon resources to provide the support needed to bring these resources online.

DEEP conducted its first procurement of renewable energy in 2011 using authority from Section 127 of Connecticut Public Act 11-80, which directed that 30 MW of Class I renewables be procured through an open, competitive RFP, and the state’s EDCs were authorized to own and operate no more than 10 MW each of that authority.

Instead of utility-only procurements, DEEP has the responsibility for procurement of renewable resources to maintain the competitiveness of the solicitation and mitigate potential utility conflicts of interest. 

Since 2011, DEEP has conducted nine procurements, resulting in contracts for:
  • 710 MW of grid-scale solar
  • 1,108 MW of offshore wind
  • 34 MW of incremental energy efficiency to the energy efficiency programs
  • 52 MW of fuel cells
  • Energy and environmental attributes from 10.9 million MWhs of nuclear power
  • Additional environmental attributes associated with 2.85 million MWhs of nuclear power
In total, DEEP is authorized by statute to procure up to 110% of the load associated with the state’s two EDCs from renewable or zero carbon energy resources. To date, Connecticut has procured the equivalent of 95% of the EDCs’ load in the forms of energy and/or environmental attributes associated with renewable energy sources.

See Historical Procurement Selections and Pricing for a list of the projects selected in grid-scale competitive procurements and the associated price.  


Future Procurements

While Connecticut has already made significant progress towards its 100% Zero Carbon Target, its commitment to procuring grid-scale renewable and zero carbon resources is further solidified through Public Act 19-71, which requires DEEP to provide a procurement schedule for OSW informed by the Integrated Resources Plan (IRP), providing for the solicitation of resources with an aggregate nameplate capacity of 2,000 MW by 2030.

In order to achieve the Target by 2040 at the least cost, it is critical to retain flexibility in planning and executing procurements so as not to procure more resources than are needed. As outlined in the IRP, the anticipated procurement activity schedule (subject to contingencies) over the next several years is:

  • 2021 & 2022: Focus on siting and permitting enhancements, transmission planning and procurement, and market reforms needed to enable procurement of additional offshore wind resources and other zero carbon Class I resources.
  • 2022: Prepare and release an updated report on market conditions and changes to the contingencies listed above, including whether a more near-term procurement of zero carbon Class I resources is necessary.
  • Prior to 2028, depending on contingencies: Procure additional zero carbon Class I resources, including OSW, with sufficient time for resources to come online.

DEEP will monitor contingencies and update its procurement schedule for OSW and other zero carbon Class I resources no less than every 12 months to account for any changing market and policy conditions through the release of the next IRP.
