Massachusetts consistently ranks among the top five states for highest commercial electricity rates in the United States. It’s not a recent development — the region has carried a meaningful premium over the national average for decades. Understanding what drives that premium is useful not just as background knowledge, but because it points directly to what commercial buyers can and cannot do to manage their costs.

Reason 1: Natural Gas Dependency and Pipeline Constraints

Roughly half of New England’s electricity generation comes from natural gas. Unlike the Mid-Atlantic or Southeast, the region lacks sufficient interstate pipeline capacity to import natural gas during peak winter demand periods without price pressure. When temperatures drop and heating demand competes with power generation for gas supply, Algonquin Citygate hub prices — the benchmark for New England gas — spike dramatically. Those spikes flow directly into wholesale electricity prices.

In the winters of 2018 and 2022, Algonquin Citygate prices exceeded $30/MMBtu and briefly spiked above $100/MMBtu, compared to the Henry Hub national benchmark of $4–6/MMBtu during the same periods. That differential translates directly into elevated electricity prices for New England commercial buyers during the highest-risk months.

Reason 2: Transmission Infrastructure Costs

New England’s transmission grid is aging and in a period of significant capital investment. ISO-NE’s regional transmission expansion plan includes hundreds of millions of dollars in new transmission infrastructure needed to connect offshore wind and other renewable resources to the grid, reinforce aging lines, and address reliability needs. Those investments are recovered through transmission charges that appear on every electricity bill in the region.

Reason 3: Renewable Portfolio Standard Compliance

Massachusetts has one of the most aggressive Renewable Portfolio Standards in the country, requiring retail electricity suppliers to source a growing percentage of supply from Class I renewable energy resources. In 2026, the Class I requirement is approximately 25% of retail sales. The cost of purchasing qualifying renewable energy certificates (RECs) to meet this standard — which has been elevated by supply constraints in the New England REC market — is embedded in all retail supply rates in the state.

Reason 4: Capacity Market Costs

As discussed in our post on the ISO-NE capacity market, every commercial electricity customer in New England pays for the regional capacity commitment — the cost of ensuring sufficient generation resources exist to meet peak demand. These capacity costs are embedded in retail supply rates and in utility default service rates alike.

What Commercial Buyers Can Actually Control

You cannot change the pipeline infrastructure, the transmission investment cycle, or the RPS requirements. But you can manage how you engage with the parts of the bill that are market-driven:

• Lock in a fixed-rate supply contract when forward prices are favorable. You can’t change the price of New England electricity, but you can protect yourself from future increases.
• Evaluate energy efficiency investments. Reducing consumption reduces the quantity of expensive New England electricity you buy.
• Understand your load profile. Improving your load factor — flattening your consumption curve relative to peak demand — can meaningfully reduce your per-kWh costs.
• Work with a broker to time your procurement. The difference between locking in rates at a market peak versus a market trough can be significant over a 24-36 month term.
