Connecticut's Energy Storage Solutions program provides anonymized data on approved battery storage projects for homes and businesses. The dataset includes system costs, sizes, contractor details, and impact metrics from the incentive application process. It is administered by the Connecticut Green Bank, Eversource, and United Illuminating, with data last updated in April 2026.
Use Cases
- Analyze the relationship between `Total System Power [kW]`, `Batteries/Storage Cost`, and `Customer Type` to model cost per kilowatt for different customer segments.
- Map project locations using `Longitude` and `County` to assess geographic distribution of energy storage adoption and identify service gaps.
- Evaluate program equity by filtering projects by `Low Income`, `LMI Qualified`, or `VintageEJCommunity` status against metrics like `Cost / kWh`.
- Forecast `Annual Peak Demand (kW)` reduction potential by modeling aggregated `Total System Power [kW]` across different `Customer Class` types.
- Assess economic impact by correlating `TotalTaxRevenueGenerated` and `Indirect and Induced Jobs` with project `Stage` and `Completed Date`.
Strengths
- Includes detailed cost breakdowns across at least 8 specific columns (e.g., `Installation Labor Cost`, `Engineering and Design Cost`).
- Contains geospatial (`Longitude`, `County`) and demographic (`Congressional District`, `Customer Class`) attributes for multi-faceted analysis.
- Tracks project lifecycle through multiple date columns (`Approval Date`, `Completed Date`, `Submitted Date`).
Limitations
- Sample size (row count) is unknown, limiting statistical reliability assessments.
- Data completeness for all columns, especially `Completed Date` for ongoing projects, is uncertain.
- Potential for geographic bias as the dataset is limited to Connecticut utility customers.
