Eversource Energy Connecticut (formerly Connecticut Light & Power) serves the majority of Connecticut — most of the state except the Greater New Haven and Greater Bridgeport areas served by United Illuminating. Eversource CT customers pay some of the highest electricity rates in New England, making solar ROI particularly strong in their territory.
Key facts for Eversource CT solar customers:

- Interconnection applications submitted by your installer through Eversource's online portal
