Data Methodology

Halcyon's Gas Power Plant Tracker compiles comprehensive information on newly proposed and under construction natural gas power plants across the United States. Drawing from state public utility commission (PUC) dockets, environmental filings, and the U.S. Energy Information Administration (EIA) datasets, the Tracker consolidates key project details into a structured, research-ready dataset.

Each project entry captures essential attributes such as docket numbers, plant and unit names, planned capacity, technology type, cost estimates, operating year, and developer or utility ownership. Where available, the dataset includes granular details such as turbine models, OEMs, hydrogen blending capabilities, environmental controls, point of interconnection, and natural gas supply sources.

Halcyon's analysts use AI-assisted search to identify relevant filings, and each data point is validated and contextualized by subject-matter experts. The result is a uniquely reliable resource for understanding the scale, timing, and characteristics of upcoming gas-fired generation across the U.S. energy landscape.

Halcyon will update the tracker on a monthly basis to incorporate new plants and update existing plants as information becomes available. We are continuously adding new data and new data fields based on your feedback.

(32 data points - 3 new data fields added) 

Field

Description

Plant / Unit Name The name of the proposed power plant or project. When applicable, this is presented at the unit level, especially if separate units are filed under different CPCN docket numbers.
CPCN Docket Number The docket number associated with the Certificate of Public Convenience and Necessity (CPCN), or in some jurisdictions, related dockets like the Certificate of Environmental Compatibility and Public Need.
Halcyon Docket Profile Page A direct link to the Halcyon profile page for the docket, providing consolidated access to filings, summaries, and related materials.
Date of Announcement The earliest official date available for the project, most often the CPCN filing date, the date of a proposed construction filing or equivalent notice.
Planned / Operating Year The planned year of commercial operation for the project, as stated in regulatory filings or related excerpts.
EIA Plant ID The plant identifier from the U.S. Energy Information Administration’s (EIA) Form 860M dataset, if the project is represented in that dataset.
Utility Name The name of the utility responsible for developing, owning, or operating the plant. For projects behind the meter or co-located with data centers, this field may reflect the project developer instead of a regulated utility.
EIA Entity Name The corresponding entity name from the EIA860M dataset, where available.
Location The stated U.S. county of the proposed facility.
State The U.S. state in which the proposed power plant is to be located.
Cost per kW The estimated or reported capital cost per kilowatt of capacity. This is either (a) explicitly stated in filings or (b) calculated by dividing total project capital expenditures (CapEx) by the planned capacity.
Capacity (MW) The proposed nameplate capacity of the facility, in megawatts, as reported in filings.
Capex ($M) The total capital expenditure for the project, expressed in millions of U.S. dollars.
Capex Details Additional detail on the reported capital cost, such as whether it reflects overnight costs, includes financing costs, or accounts for Allowance for Funds Used During Construction (AFUDC).
Technology Type The technology configuration of the proposed facility, as described in filings (e.g., “Simple Cycle Gas Turbine,” “Combined Cycle Gas Turbine,” “Reciprocating Engine”). If the project involves converting an existing coal facility to gas, this field is noted as “Conversion.”
Hydrogen Capable Indicates whether the proposed units are designed or planned to operate with the ability to blend hydrogen into the natural gas fuel.
Hydrogen Blending Threshold The maximum percentage of hydrogen that can be blended into the fuel supply, if specified in filings.
Units/ Turbines Count The number of turbine or engine units planned for the project.
Unit size (MW) The individual capacity rating, in megawatts, of each turbine or engine unit.
Unit Model The model designation of the turbine or engine proposed for the project, if specified in filings.
OEM The original equipment manufacturer (OEM) of the turbine or engine technology.
EPC The entity contracted to provide Engineering, Procurement, and Construction (EPC) services for the facility, where identified.
FEED The vendor responsible for conducting Front-End Engineering Design (FEED) studies, if disclosed.
Power Market The wholesale power market, balancing authority, or Regional Transmission Organization or Independent System Operator (RTO/ISO) in which the plant is expected to sell power.
Point of Interconnection (NEW) The designated interconnection node or substation where the facility is planned to connect to the transmission grid.
Natural Gas Supply (NEW) The natural gas pipeline or supply source expected to serve the facility, including specific node names where disclosed.
Environmental Equipment (NEW) Details on environmental control technologies to be installed or procured, such as selective catalytic reduction (SCR), scrubbers, or catalytic converters.
EIA Status The project’s status as reported in the EIA860M dataset, where available.
Actual vs. Estimated Cost Indicates whether reported costs are actual (incurred or budgeted) or estimated (forecasted or modeled).
Dollar Year The reference year of reported capital cost values, if explicitly stated. If not provided, the dollar year defaults to the publication date of the filing.
Source Link X Links to the regulatory filings from which the project data was extracted. Multiple links may be provided where relevant.
Source Link X Publication Date The publication date of the corresponding source document.
