Solicitations for Large-Scale Renewables


2023 RES Solicitation for Tier 1 RECs

NYSERDA launched the seventh annual Renewable Energy Standard (RES) request for proposals, RESRFP23-1, to continue accelerating progress toward Governor Hochul’s target of generating 70 percent of New York State’s electricity from renewable sources by 2030. Through the 2023 solicitation, NYSERDA seeks to procure Tier 1 eligible Renewable Energy Certificates (RECs) from eligible facilities that enter commercial operation on or after January 1, 2015, and on or before May 31, 2026, unless extended to May 31, 2029.

RESRFP23-1 is implemented through a two-step process, consisting of:

  1. Step One Eligibility Application: A qualifying step through which the proposer must provide evidence that the Bid Facility is Tier 1 eligible and other general information about the Proposer and the Bid Facility. All Step One Eligibility Applications must be submitted via the RESRFP23-1 solicitation website and were due on Thursday, December 28, 2023 at 3:00 p.m. ET.
  2. Step Two Bid Proposal: A competitive Bid Proposal step, through which NYSERDA will:
    1. Examine Bid Proposals to determine whether they demonstrate that the Bid Facility and Proposer meet the Minimum Threshold Requirements; and
    2. For Bid Proposals that meet those Minimum Threshold Requirements, perform a competitive evaluation based on price and non-price factors.

Step Two Bid Proposals were due on Wednesday, January 31, 2024 at 3:00 p.m. ET.

RESRFP23-1 Step Two Bid Proposal Response

Following the release of the Governor’s 10-Point Action Plan, NYSERDA has garnered significant competitive interest in its seventh and expedited Tier 1 solicitation (RESRFP23-1) which closed on January 31, just two months after its launch. NYSERDA received bids from 20 developers for 57 projects, comprising five gigawatts (GW) of capacity. In total, 51 of the 57 projects submitted for the Step Two evaluation process are projects that were previously awarded NYSERDA Renewable Energy Certificate (REC) contracts and terminated their contracts to participate in this solicitation. NYSERDA is evaluating the bids and expects to make public versions of the bids available on NYSERDA’s website in the near future and to announce conditional awards in April.

Associated Documents

2023 RES Solicitation Request for Information (RESRFI23-1)

Interested stakeholders were invited to review and comment on proposed updates and modifications to the 2023 Tier 1 solicitation (RESRFP23-1) under this Request for Information (RFI). This feedback is assisting NYSERDA in finalizing the solicitation prior to its release.

The RFI document is linked below.

2023 Large-Scale Renewables Capacity Accreditation Request for Information (LSRRFI23-1)

Under this Request for Information (RFI), NYSERDA sought external stakeholder review and comment on NYSERDA’s proposed modifications to existing and future Index REC and Index OREC contracts to account for revisions to the Market Administration and Control Area Services Tariff proposed by the New York Independent System Operator, Inc. and approved by the Federal Energy Regulatory Commission to adopt a marginal capacity accreditation market design. This feedback has assisted NYSERDA in finalizing its proposed approach in consultation with the Department of Public Service.

Project Siting and Permitting Resources

These resources can help inform proposers’ decisions regarding project siting for future solicitations.

Disadvantaged Communities

The Climate Act directs the Climate Justice Working Group (CJWG) to establish criteria for defining Disadvantaged Communities. On March 27, 2023, the CJWG voted to finalize Disadvantaged Communities criteria. Additional resources for identifying Disadvantaged Communities are located on the New York Climate Act website Link opens in new window - close new window to return to this page.. This interactive map identifies areas throughout the State that meet the final criteria identified for a disadvantaged community as defined by New York State at the time of the 2023 Tier 1 solicitation, RESRFP23-1.

Agricultural Mitigation Resources

In order to facilitate the protection of agricultural lands in the state’s Agricultural Districts, Proposers awarded under RESRFP23-1 may be responsible for making an agricultural mitigation payment to a designated fund based on the extent to which the solar project footprint overlaps with New York’s highest quality agricultural soils, identified as Mineral Soil Groups classifications 1 through 4 (MSG 1-4). This mitigation approach intends to set a benchmark for potential agricultural mitigation payments, which solar project developers may be able to reduce by minimizing the facility’s impact on MSG 1-4 and/or introducing or retaining agricultural productivity on the project site. Instances where Proposers cannot avoid or minimize impacts on MSG 1-4 will result in a payment to a fund administered by NYSERDA in consultation with the Department of Agriculture and Markets to support ongoing regional agricultural practices.

An interactive map of statewide MSG 1-4 and downloadable files containing the same MSG 1-4 data are available at the link below for the use of Proposers and other interested parties.

Operational Flexibility and Grid Resources

The following NYSERDA, DPS, and NYISO studies and stakeholder proceedings are encouraged for use to inform Proposers’ due diligence. Proposers should note that these resources are subject to additional updates and may be amended by other applicable studies and/or updated assessments and public data.

In 2020, New York State passed the Accelerated Renewable Energy Growth and Community Benefit Act [PDF] to accelerate progress towards the State’s nation-leading clean energy goals. The Act instructed the State to conduct a Power Grid Study to inform transmission system investments that will be necessary to achieve the clean energy goals of the Climate Leadership and Community Protection Act (Climate Act). The Power Grid Study is comprised of three component studies: 1) a joint utilities study on local transmission and distribution needs; 2) an offshore wind study of bulk-power transmission needs; and 3) a statewide transmission analysis to achieve the Climate Act goals. To read the studies, review public comments, and engage in the public process, visit the Department of Public Service Matter Master 20-00905/20-E-0197Link opens in new window - close new window to return to this page. or access the studies below.
