Expert ISO-NE market navigation and competitive energy procurement for Connecticut businesses across Eversource and United Illuminating territories, covering electricity and natural gas.
Connecticut deregulated its electricity market in 2000 and natural gas market in 1996, allowing commercial and industrial customers to choose their energy supplier while maintaining reliable delivery through regulated utilities.
Connecticut businesses can choose from multiple competitive electricity suppliers, potentially saving 20-30% versus standard service rates. The competitive market offers flexible contract terms, fixed pricing options, and customized energy solutions tailored to your operations.
Connecticut commercial natural gas customers have had supplier choice since 1996, one of the earliest deregulated gas markets in the nation. This mature market offers stable pricing, diverse suppliers, and significant savings for businesses with gas heating, cooking, or industrial processes.
Connecticut participates in the ISO New England (ISO-NE) regional electricity market, coordinating generation and transmission across six New England states for reliable supply. This structure delivers market efficiency, resource adequacy, and competitive wholesale pricing.
Eversource and United Illuminating continue to deliver electricity and maintain infrastructure regardless of your supplier. You'll receive one consolidated bill, keep the same reliable service, and have the utility handle all technical issues and outages as before.
ISO New England operates the wholesale electricity market and manages the power grid across Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont.
ISO-NE operates both day-ahead and real-time electricity markets where generators bid to supply power and load-serving entities buy it. These competitive markets set clearing prices based on supply and demand, creating opportunities for strategic procurement and cost management.
Connecticut businesses pay capacity costs through the Forward Capacity Market, which ensures adequate generation resources three years ahead. These charges appear on your utility bill and can represent 20-30% of total electricity costs, making supplier selection critical.
ISO-NE uses locational marginal pricing (LMP), reflecting the cost of delivering electricity to specific locations based on generation costs, transmission congestion, and line losses. Understanding LMP patterns in Connecticut load zones helps optimize contract timing and structure.
The regional transmission organization (RTO) structure gives Connecticut businesses access to diverse generation across New England, improved grid reliability, and market transparency. This approach reduces costs through shared infrastructure and coordinated planning.
ISO-NE manages growing renewable resources including wind, solar, and hydroelectric power that cut emissions and provide long-term price stability. Connecticut businesses can leverage these options through renewable energy certificates (RECs) and green power programs.

Hospitality Energy →Connecticut has established aggressive clean energy goals requiring 100% zero-carbon electricity by 2040, creating opportunities and requirements for businesses to participate in renewable energy programs.
Connecticut's RPS requires suppliers to provide rising percentages of renewable energy, reaching 44% by 2030 and 100% zero-carbon by 2040. These mandates affect supplier pricing through Renewable Energy Certificate (REC) requirements and let businesses procure renewable energy directly.
Connecticut distinguishes Class I renewables (solar, wind, fuel cells, hydroelectric, sustainable biomass) from Class II resources (existing facilities and energy efficiency). Understanding these classifications helps businesses select the right renewable energy products and meet corporate sustainability commitments.
Connecticut businesses with on-site solar can generate SRECs that provide revenue for 15 years under the ZREC and LREC programs. We help commercial solar projects maximize SREC value while optimizing behind-the-meter production and net metering benefits.
The nation's first Green Bank finances renewable energy and efficiency projects, including Commercial Property Assessed Clean Energy (C-PACE) loans repaid through property taxes. These programs cut upfront costs for solar, storage, LED lighting, and HVAC upgrades while delivering immediate savings.
Connecticut allows virtual net metering for businesses unable to host on-site solar, enabling participation in community solar or remote solar facilities. This delivers renewable energy benefits without property modifications or capital investment.
We facilitate renewable energy procurement options including bundled renewable electricity supply, unbundled REC purchases, virtual power purchase agreements (VPPAs), and physical PPAs. These strategies meet corporate sustainability goals, reduce Scope 2 emissions, and demonstrate environmental leadership.
Connecticut utilities offer Standard Service as the default electricity supply, but most businesses save significantly by choosing competitive suppliers.
Eversource's Standard Service rates adjust every six months based on wholesale market and capacity prices. Commercial customers typically pay more on Standard Service than with competitive suppliers due to regulatory cost recovery, risk premiums, and procurement timing. Fixed-price competitive contracts eliminate rate volatility and provide budget certainty.
UI Standard Service operates similarly, with semi-annual rate adjustments reflecting ISO-NE wholesale prices. UI commercial customers often see significant rate swings between summer and winter, making fixed-price competitive supply attractive for financial planning and cost control.
Connecticut businesses pay capacity costs under both Standard Service and competitive supply, but competitive suppliers often offer more favorable capacity pricing. Understanding Forward Capacity Market (FCM) costs and how they're allocated in your rate class helps identify savings opportunities.
Utilities still charge transmission and distribution costs regardless of your supplier choice. These regulated charges cover power line maintenance, grid infrastructure, and system improvements. We analyze your rate class to ensure proper billing and identify demand charge optimization opportunities.
Competitive suppliers offer fixed pricing, flexible contract terms, renewable energy options, and customized products unavailable through Standard Service. Connecticut businesses typically save 20-30% by switching, gaining predictable costs, no rate shock, and strategic contract timing.
Capacity costs represent a significant portion of Connecticut electricity bills, often 20-30% of total expenses, requiring strategic management.
ISO-NE's Forward Capacity Market ensures adequate generation three years in advance by requiring load-serving entities to purchase capacity. Connecticut businesses pay this as a $/kW charge based on peak demand during ISO-NE system peaks, making demand management during peak periods critical.
Your capacity obligation is set by your usage during ISO-NE's system peak hours (typically summer afternoons). Reducing consumption during these critical periods can significantly lower annual capacity costs. We provide peak demand alerts and demand response strategies to minimize capacity tags.
While capacity costs flow through all electricity supply, competitive suppliers structure capacity charges differently than utilities. Some offer pass-through with detailed monthly reporting, while others include capacity in fixed per-kWh pricing. Understanding your capacity exposure helps select optimal contract structures.
Participating in demand response during ISO-NE peak periods reduces capacity obligations and can generate revenue. Connecticut businesses with flexible operations or backup generation can enroll in programs like ISO-NE's Demand Capacity Resource (DCR) or state programs through the utilities and competitive suppliers.
Connecticut deregulated natural gas in 1996, creating one of the nation's most mature competitive gas markets with significant savings opportunities.
Connecticut businesses can lock in fixed natural gas prices for 1-5 years, eliminating exposure to volatile spot pricing and providing budget certainty for heating and industrial processes. These contracts protect against winter price spikes when demand peaks across New England.
Connecticut Gas Corporation (CNG) serves Hartford and central Connecticut, Southern Connecticut Gas (SCG) serves New Haven and coastal areas, and Yankee Gas distributes statewide. All three utilities let commercial customers choose competitive gas suppliers while continuing reliable delivery.
Some businesses prefer index-based natural gas pricing tied to NYMEX or regional basis points, with or without price collars. Hybrid contracts combine fixed winter pricing with index summer pricing, optimizing cost management around seasonal usage patterns.
Natural gas suppliers handle transportation from pipelines to your facility and manage daily balancing. Connecticut's connection to multiple interstate pipelines including Algonquin, Tennessee, and Texas Eastern provides supply diversity and competitive pricing, especially valuable during peak winter demand.
Commercial gas customers pay both commodity charges ($/therm) and demand charges ($/therm/day) based on peak daily usage. We optimize rate classes, analyze firm vs. interruptible service, and structure contracts to minimize total delivered cost including utility charges.
