Research evidence brief
Executive Summary

Research summary

Question, evidence, supported findings, and the limits that affect the decision.

Ameresco Inc. operates solar capacity in Illinois, with one plant, DePue Holdings, LLC, having a total capacity of 20 MW.

Ameresco Inc. operates biomass and solar capacity in South Carolina, with Savannah River Site Biomass Cogen (20.8 MW biomass) and MCRD Parris Island PV Hybrid (17 MW multi-fuel including solar) identified.

This is a focused evidence brief, not a complete decision report. It preserves the useful findings while making the decision-critical gaps explicit.

Research findings

Ameresco operates landfill gas (LFG) capacity in California, with facilities such as Ameresco Ox Mountain (14.4 MW) and Ameresco Chiquita Canyon (9.2 MW).

Why it matters: AMERESCO Ox Mountain Energy LLC and AMERESCO Chiquita Canyon LLC are listed as the utility_eia_name and canonical owner for these plants.

Ameresco operates battery storage capacity in Colorado, with four identified plants (Rattlesnake Ridge Battery Storage, Keenesburg Battery Storage, Bromley Battery Storage, Davis Battery Storage) each having a total capacity of 11.8 MW.

Why it matters: Ameresco is identified as the GEM entity and canonical owner for these plants.

Ameresco Inc. has three active solar projects in the PJM queue in Virginia, with capacities of 19.67 MW, 11.891 MW, and 9.87 MW respectively, totaling approximately 41.43 MW.

Why it matters: Ameresco Inc. is identified as the developer for all three projects.

The provided operating assets data (E1) is a partial result set and does not represent a comprehensive list of all Ameresco's operating assets, thus preventing a complete capacity comparison across states.

Why it matters: N/A

Evidence gaps

  • InfraSure did not report an authoritative dataset refresh timestamp for the operating assets or queued projects data, making it impossible to determine the freshness of the information.
  • The available records are a bounded snapshot; a complete population was not established.
  • The source did not report an authoritative data date, so current-state conclusions remain preliminary.

claim-level citations and limits
C1supportedlow confidence

Ameresco Inc. operates solar capacity in Illinois, with one plant, DePue Holdings, LLC, having a total capacity of 20 MW.

E1

This claim is based on a partial dataset of operating assets, so it may not represent Ameresco's entire operational footprint.

C2supportedlow confidence

Ameresco Inc. operates biomass and solar capacity in South Carolina, with Savannah River Site Biomass Cogen (20.8 MW biomass) and MCRD Parris Island PV Hybrid (17 MW multi-fuel including solar) identified.

E1

The MCRD Parris Island PV Hybrid plant has multiple fuel types including diesel fuel oil, municipal solid waste, natural gas, and solar. The canonical owner of MCRD Parris Island PV Hybrid is MCRD Parris Island / U.S. Marine Corps, not Ameresco directly. This claim is based on a partial dataset of operating assets, so it may not represent Ameresco's entire operational footprint.

C3supportedlow confidence

Ameresco operates landfill gas (LFG) capacity in California, with facilities such as Ameresco Ox Mountain (14.4 MW) and Ameresco Chiquita Canyon (9.2 MW).

C5supportedlow confidence

Ameresco Inc. has three active solar projects in the PJM queue in Virginia, with capacities of 19.67 MW, 11.891 MW, and 9.87 MW respectively, totaling approximately 41.43 MW.

E3

These projects are in the queue and their operational status or completion is not confirmed by this evidence. The evidence is for projects in the PJM region, which may not encompass all of Ameresco's queued projects.

C6directionallow confidence

The provided operating assets data (E1) is a partial result set and does not represent a comprehensive list of all Ameresco's operating assets, thus preventing a complete capacity comparison across states.

E1

The partial nature of the data means any statewide capacity totals derived from this evidence would be incomplete.

C7blockedblocked confidence

InfraSure did not report an authoritative dataset refresh timestamp for the operating assets or queued projects data, making it impossible to determine the freshness of the information.

E1E3

Without a data_as_of timestamp, the currency of the information cannot be established.
