The Town of Huntington NY Prize concept linked Town Hall-area civic loads, Huntington Hospital, and the wastewater treatment plant through a 13.8 kV community microgrid. Its Stage 1 design proposed a 2.8 MW fuel-cell CHP system, 400 kW reciprocating-engine CHP, a 1.3 MW peaking generator, 560 kW of PV, 2 MW/2 MWh battery storage, a 100 kW flywheel, and 900 kW of existing diesel generation. Huntington won US$1 million for Stage 2 detailed engineering in 2017, but NYSERDA later ended the Stage 3 funding path; no construction or commissioning evidence was found.

Research status
Feasibility and detailed-engineering work completed or substantially advanced, but the community microgrid was not built. In October 2020 the Town stated that NYSERDA was no longer pursuing NY Prize and that no Stage 3 funding would be available. A 2021 federal research proposal referenced the facilities, but it is not evidence that the NY Prize design entered construction.

System evidence

Energy mix, capacity, and specifications

Values can describe different project phases, generation sources, storage systems, or other components. Source citations are attached to each figure so discrepancies remain visible.

Storage
NA [1]
Proposed fuel-cell CHP
2.8 MW natural-gas fuel cell at Huntington Hospital [2]
Proposed battery
2 MW / 2 MWh battery and inverter at Huntington Hospital [2]
Town Hall-area resources
400 kW natural-gas reciprocating-engine CHP, 560 kW PV, and 100 kW flywheel [2]
Wastewater-plant resources
1.3 MW natural-gas peaking generator, 400 kW natural-gas/biogas CHP, and an existing 900 kW diesel generator [2]
Aggregate design capacity
Approximately 7.7 MW including PV and the existing diesel unit; the report also uses a 6.9 MW figure excluding those resources [2]
Interconnection
Three 13.8 kV points of common coupling on the PSEG Long Island system [2]

Approximately 0.464 mile of underground 13.8 kV cable between the wastewater plant and hospital [2]
Peak reduction
Modeled grid peak reduction of approximately 3.7 MW [2]
Stage 2 award
US$1 million in 2017 for audit-grade design and engineering [3][4]

Technical record

Architecture, performance, and project updates

Concise technical facts, milestones, operating results, and later developments. Dated notes distinguish historical design claims from current evidence.

  • General

    The feasibility study will evaluate adding methane and natural gas fired generation with waste heat recovery, solar power, and energy storage technologies. [1]

  • Generation

    Methane and natural gas fired generation with waste heat recovery, solar power, and energy storage technologies [1]

  • Topology

    The proposed ring connected the wastewater plant and hospital underground, while an overhead link reached the Town Hall area. The Town Hall cluster was designed to retain an independent island if the overhead tie failed. [2]

  • Island transition

    Storage would bridge transitions and regulate voltage and frequency while dispatchable generators started; the fuel cell was treated as grid-following rather than the primary grid-forming source. [2]

  • Load management

    The control concept shed load to about 80% of available online distributed-generation capacity and restored loads according to criticality and reserve. [2]

  • Battery operation

    The feasibility design targeted roughly 70–80% state of charge before a forecast islanding event to preserve transition reserve. [2]

  • Program history

    Huntington moved from a US$100,000 Stage 1 study to a US$1 million Stage 2 engineering award in 2017 and was preparing for Stage 3 by 2019. [3][4][6]

  • Program outcome

    The Town reported in October 2020 that NYSERDA would not offer Stage 3 construction funding and sought FEMA BRIC funding instead. No evidence located shows that alternative funding produced the designed microgrid. [6]

  • Later research proposal

    A January 2021 Town resolution supported a DOE Connected Communities proposal with Ecogy, Brookhaven National Laboratory, Stony Brook University, and Pacific Northwest National Laboratory; this was a proposal, not commissioning documentation. [7]
