Nassau County's 2016 NY Prize feasibility study evaluated a community microgrid centered on the Bay Park Sewage Treatment Plant and nine other critical facilities in East Rockaway, New York. It compared an advanced-digestion/biogas CHP core with wind, solar, fuel-cell, and legacy tri-fuel generation options; the report did not document a selected construction design. No later NY Prize construction award or commissioned community microgrid was found, and a later Bay Park electrical-upgrade project says the plant's four old 3.6 MW engine-generators were decommissioned after new utility feeders were installed.

Research status
Feasibility study completed in 2016; no construction or commissioning verified through July 2026. East Rockaway does not appear on NYSERDA's published Stage 2 award list, and later Bay Park work replaced the legacy on-site generation role with upgraded utility connections, so the public evidence supports a stopped-after-feasibility outcome rather than an operating microgrid.

Project delivery

Who was involved in East Rockaway – Bay Park Microgrid Feasibility Study – NYSERDA – NY Prize Stage 1?

10 publicly identified organizations. Where a recovered source named a participant without explaining its work, the role remains explicitly unspecified.

Organization

H2M architects + engineers

Engineer for the later Bay Park Phase E4 utility-connection work that documented decommissioning of the plant's old engine-generators [5]

Organization

LIPA

Publicly named participant; role not specified in the recovered record [1]

Organization

Long Island Power Authority

Public power authority named as a Stage 1 project partner [3]

Organization

Nassau County

NY Prize applicant, feasibility-study sponsor, proposed microgrid owner, and owner of the Bay Park wastewater plant [2][3]

Organization

National Grid

Natural-gas utility named as a Stage 1 project partner [3]

Organization

New York State Energy Research and Development Authority

NY Prize program administrator and Stage 1 feasibility-study funder [3][4]

Organization

PSEG

Publicly named participant; role not specified in the recovered record [1]

Organization

PSEG Long Island

Electric utility and study partner that supplied system and load information [3][2]

Organization

United Water Long Island (later SUEZ)

Wastewater-plant operator and project partner involved in evaluating generation and treatment-process integration [3][2]

Organization

Village of East Rockaway

Proposed principal community customer and owner of several targeted critical facilities [2]

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 advanced-digestion CHP
2.5 MW reciprocating-engine CHP fueled by digester gas; modeled for continuous operation and 21,900 MWh/year [2]
Other evaluated new resources
1 MW wind, 1.5 MW solar, and 1 MW fuel cell using natural gas and/or digester gas; these were alternatives or optional phases, not a documented final build package [2]
Legacy generation represented in the study
5.5 MW of available tri-fuel engine capacity in the resource table, with digester-gas production limiting sustained biogas output to about 2.5 MW [2]
Targeted facilities
Bay Park Sewage Treatment Plant plus East Rockaway Village Hall, three public schools, two fire facilities, the public library, public works, and the post office [2]
Bay Park study load
The feasibility report listed the wastewater plant at 7.5 MW and 65.7 GWh/year, far larger than the other proposed community loads [2]
Storage
No electrical energy-storage system was specified in the reviewed feasibility design [2]
Feasibility benefit-cost ratio
2.2 in the NY Prize screening analysis [2]

Controls and hardware

Equipment and controller details

Manufacturer and model are shown only when a source names them. Generic descriptions are not converted into guessed product assignments.

01

Existing engine-generators

Model not publicly disclosed

The study evaluated the plant's aging tri-fuel engine-generators as an interim islanding resource. A later H2M project page describes four 3,600 kW units at the site and says they were decommissioned; manufacturer and model were not disclosed in the reviewed sources. [2][5]

02

Proposed CHP

Model not publicly disclosed

A 2.5 MW reciprocating engine was preferred over microturbines for the digester-gas CHP concept, but no supplier or model was selected in the public report. [2]

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.

  • Generation

    The proposed microgrid would combine natural gas generation with a newly-installed biogas-to-power engine, powered by gas created through waste anaerobic digestion, and combined heat and power (CHP) [1]

  • Architecture

    The concept placed generation inside the wastewater-plant fence and proposed a new 5 kV community distribution system outside it. Islanded operation was designed not to depend on utility communications, and the preferred generation path was to be black-start capable. [2]

  • Resource-plan caveat

    The report's capacity table combines existing resources and mutually exclusive or staged options. Its figures should not be added together as though every resource was contracted for one final plant. [2]

  • Customer model

    The proposal served public and institutional critical facilities rather than residential customers. Nassau County would own the central source, the Village would be the main customer, and the U.S. Postal Service site would have required a separate participation agreement. [2]

  • Outcome evidence

    The project received Stage 1 feasibility funding but is absent from the complete published Stage 2 award list. That absence is evidence of no NY Prize Stage 2 award, not a formal cancellation notice. [3][4]

  • Later site update

    H2M's later Bay Park Phase E4 work reports a present peak load of about 6 MW, new utility-feeder connections, and decommissioning of four old 3.6 MW engine-generators. The reviewed page does not describe the 2016 community microgrid as having been built. [5]

  • Public evidence gap

    No commissioning record, as-built one-line, equipment award, operating data, or explicit project-cancellation notice was found through July 2026. [4][5]
