Connecticut Virtual Power Plant Battery Loadshape at 15-Minute Intervals

Connecticut's Energy Storage Solutions (ESS) program provides an aggregate time series of battery charging and discharging activity for enrolled residential and commercial sites. The dataset shows average system power at 15-minute intervals, with positive values for charging and negative values for discharge. It is administered by the Connecticut Green Bank, Eversource, and United Illuminating under the oversight of the Public Utilities Regulatory Authority.

Use Cases

• Modeling grid load balancing based on aggregate battery charge/discharge cycles.
• Analyzing residential versus commercial energy storage usage patterns.
• Forecasting virtual power plant capacity based on historical performance telemetry.

Strengths

• Data is provided at a high temporal resolution of 15-minute intervals.
• Telemetry data undergoes ongoing quality control and assurance processes.
• Distinguishes between activity from residential and commercial host sites.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Connecticut program.
