Why It Matters
Connecticut regulators have authorized a structural shift in how electric utilities acquire power, moving away from rigid fixed-price contracts toward a more flexible procurement model. The change aims to balance cost savings for ratepayers with protections against volatile wholesale market fluctuations.
What Happened
The Public Utilities Regulatory Authority (PURA) voted unanimously on Wednesday to approve a framework for “dynamic” electricity procurement. The decision fulfills a mandate from a bipartisan energy-savings bill passed by state lawmakers in 2025, which required the agency to implement new purchasing procedures.
Currently, Eversource and United Illuminating secure nearly all power for standard service customers through fixed-price contracts lasting six months with wholesale suppliers. These wholesalers include power plant operators and firms trading on ISO New England markets. Under the new system, utilities will be permitted to purchase approximately 20% of their electric load directly from wholesale markets.
PURA Chairman Thomas Wiehl said the decision “is a positive step forward in improving our procedures to procure energy at the best price for Connecticut ratepayers, while preserving important safeguards from market volatility.”
The shift addresses the reality that wholesale electricity prices can change every five minutes based on weather, demand, and natural gas availability. Natural gas remains the primary fuel source for most regional power plants. In Connecticut’s deregulated structure, utilities do not own or profit from generation; instead, they pass generation costs to customers through supply charges without markup.
By the Numbers
5-0 — PURA vote count to approve the framework.
20% — Target percentage of electric load utilities will procure directly from wholesale markets.
Six-month — Duration of current fixed-price contracts with wholesale suppliers.
Every five minutes — Frequency at which wholesale electricity prices can change.

The move reflects a broader trend in energy policy where regulators seek to introduce flexibility into utility purchasing without exposing consumers to unchecked market risks. Consumer Counsel Claire Coleman noted that the approach builds “enough flexibility into the framework to benefit from lower-cost opportunities as they become available while maintaining protections that help shield customers from sudden changes and volatile swings in energy markets.”
While specific customer savings amounts remain unknown, the model allows utilities to capitalize on periods of low wholesale prices. This contrasts with the previous system, which locked in rates regardless of short-term market dips or spikes.
What’s Next
PURA has until February to draft a detailed implementation plan for the dynamic procurement model. Impacts on customer bills are expected to appear in mid-2027 or early 2028, once the new purchasing strategies are fully operational.
