Connecticut Electricity Information

Connecticut has a fully deregulated electricity market, giving residents and businesses the ability to choose their electricity supplier. Utilities like Eversource and United Illuminating still manage delivery and grid reliability, but the supply portion of the bill is open to competition. Customers can shop among dozens of competitive energy suppliers for fixed-rate plans, renewable energy options, or promotional deals, while their local utility remains responsible for safe and reliable service. This system gives households and businesses flexibility and control over their electricity costs while fostering competition and innovation in the state’s energy market.

Connecticut’s electricity is primarily generated from natural gas, which dominates the state’s power mix by a wide margin. Nuclear energy also plays a significant role, providing steady, carbon-free electricity, while renewables like solar and hydropower continue to grow. The state is also investing in offshore wind to further diversify its energy sources.

Electricity consumption in Connecticut is moderate, but prices are among the highest in the country due to transmission costs and reliance on imported fuels. On the bright side, the state has lower emissions than many others, thanks to its strong nuclear presence and clean energy initiatives. With continued investments in renewables and energy efficiency, Connecticut is working toward a greener and more affordable energy future.

Connecticut’s electricity consumption reflects a New England climate with cold, snowy winters and warm, humid summers. Winter demand rises for lighting and electric heat in homes that use heat pumps or resistance heat, although many households rely on natural gas or oil for primary heating. Summer usage climbs during heat waves as air conditioning becomes essential, especially in coastal and urban areas. A dense population, a sizable commercial sector, and widespread efficiency programs shape the overall profile, keeping per-capita use moderate while seasonal peaks remain pronounced.

Connecticut Natural Gas Information

Connecticut relies heavily on natural gas for both heating and power generation, a sharper shift compared with many Northeastern neighbors that still depend on heating oil. Cold winters push demand up as households use gas for space and water heating, while hot, humid summers drive power plants to burn more gas to cover air-conditioning loads. Since the state has no in-state production, nearly all natural gas is delivered via interstate pipelines, making reliability and storage just as critical as cost.

For households, the market is regulated and utilities such as Eversource Gas, Southern Connecticut Gas, and Connecticut Natural Gas purchase and deliver fuel. The picture changes for businesses, where commercial and industrial customers can choose their supplier. This limited deregulation gives larger energy users more flexibility to manage costs and contracts, while residential customers remain tied to their utility’s supply. The result is a system designed to balance affordability and reliability through sharp seasonal swings, with natural gas serving as both a household heating essential and a backbone for the grid.
