WASHINGTON, Nov. 5, 2026 — Democratic victories in the 2026 midterm elections have given the party greater control over state governments and utility regulators, creating opportunities for legislation on renewable energy, electricity affordability and data center power use. The results could affect utility investment, clean energy development and the cost of electricity for households.

Democrats won gubernatorial races in Georgia, Iowa, Nevada, Ohio and Texas, and were also likely to win Alaska's governor’s race. The party gained control of both legislative chambers in Michigan, Minnesota, New Hampshire, Pennsylvania and Wisconsin, where Republicans previously held at least one chamber. Democrats also had favorable prospects in Arizona, where results in legislative races remained outstanding.

By January, Democrats are expected to hold full control of state government in at least 21 states, up from 16 before the elections. The five new Democratic trifectas are in Michigan, Minnesota, Nevada, Pennsylvania and Wisconsin. The party also ended Republican trifectas in Georgia, Iowa, New Hampshire, Ohio and Texas.

Democrats also won control of Congress, creating an opportunity to pursue federal climate legislation. President Donald Trump's veto authority, however, will limit what lawmakers can enact without sufficient votes to override a veto. State governments have more direct authority over many energy decisions, giving Democratic governors and legislators opportunities to pursue policies at the state level.

State Powers Over Energy Policy

State governments regulate several areas of the energy sector, including the types of power plants utilities can build or must close, building efficiency requirements, and industrial pollution limits. Governors and lawmakers can also establish clean electricity standards and determine how utilities serve customers.

Jay Inslee, former governor of Washington, said state governments have authority to enact many policies intended to reduce carbon emissions.

“Almost every policy you can think of to decarbonize our economy, except maybe border adjustment taxes, can be done at a state level,” Jay Inslee, former governor of Washington state, said at a Wednesday press conference.

Washington has adopted a carbon cap-and-invest program, a 100% clean electricity standard, incentives for electric vehicles and charging stations, and building codes that Inslee described as among the nation’s leading standards. He said these policies could remain in place despite opposition from the Trump administration.

About two dozen states have policies calling for electricity generation to become 100% renewable, carbon-free or carbon-neutral within specified periods. Almost all were enacted when Democrats held sufficient political control to overcome Republican opposition.

Inslee also noted that Democratic state governments do not have to wait for Congress to enact many clean energy policies.

States Consider New Energy Measures

A post-election assessment by BloombergNEF identified the new Democratic trifectas as potential sources of legislation affecting renewable energy, battery storage, heat pumps and electric vehicles. State governments could also consider requirements for data centers to use clean electricity and measures to limit costs for residents.

Michigan’s Democratic leaders are considering additional climate and energy legislation after Republican lawmakers attempted to repeal the state's 2040 target for 100% clean energy earlier this year. The election restored Democratic control of both legislative chambers and the governor's office.

In Minnesota, two years of partisan deadlock in the state House had delayed proposals concerning virtual power plants and plug-in solar systems. With Democrats regaining control of the chamber, those bills have a better chance of moving forward.

Trish Demeter, managing director at clean energy trade group Advanced Energy United, identified Pennsylvania as another state where clean energy legislation could gain ground. Advocates are seeking changes to the state's permitting and siting rules for large wind, solar and battery projects. The proposed reforms would address administrative requirements that can delay construction.

Pennsylvania environmental groups are also tracking about a dozen environmental and clean energy bills that Republicans had blocked in the state Senate. Among them is a legislative package backed by Democratic Gov. Josh Shapiro that would establish pollution, clean energy and affordability requirements for data centers. Another proposal would widen access to distributed solar and other energy resources.

In Wisconsin, Democrats have regained full control of state government for the first time in 16 years. Clean energy advocates are seeking limits on utility spending for fossil fuel plants intended to serve data centers, along with greater investment in solar, wind and battery storage. Advanced Energy United is lobbying Wisconsin Democrats for stricter utility planning requirements.

Arizona and Nevada could also see policies affecting solar and battery development. Both states have established solar industries, and their Democratic leadership could pursue measures affecting additional projects.

Changes in Utility Regulation

The election results also affected utility oversight. In Georgia, Democratic candidates won two seats on the Public Service Commission, giving the party a 3–2 majority and ending two decades of Republican control. The Solar Energy Industries Association spent money to promote the Democratic candidates.

The commission regulates utilities, including Georgia Power. The newly elected Democratic majority could work with Gov.-elect Keisha Lance Bottoms to increase consumer access to rooftop solar and energy efficiency. The commission could also give greater priority to clean energy and battery storage rather than natural gas-fired power plants as utilities address uncertain demand from data centers.

The end of Republican trifectas in Georgia, Iowa, New Hampshire, Ohio and Texas could also affect state policies toward fossil fuels and clean electricity. BloombergNEF noted that the results could limit state backing for fossil fuel development and restrictions on clean energy. Texas Republicans have pursued policies favoring fossil fuel production and opposing certain clean energy measures in recent years, although some proposals have failed.

Electricity Affordability

Electricity bills featured prominently in the campaigns. Democratic gubernatorial winners Keisha Lance Bottoms in Georgia, Amy Acton in Ohio and Gina Hinojosa in Texas campaigned on clean energy development, lower utility bills and oversight of data center construction.

Caroline Spears, executive director of Climate Cabinet, said affordability concerns repeatedly came up in conversations with voters. The group backed 120 candidates during the election cycle. As of Wednesday morning, 86 had won, nine had lost, and 24 races remained too close to call.

“This was the affordability election,” Spears said during a press briefing. She added that voters repeatedly raised utility bills, electricity prices and gasoline prices.

Spears said clean energy development could also reduce electricity costs. Solar, wind and battery projects are cheaper and can be built faster than gas-fired power plants, she said. These technologies accounted for more than 90% of new additions to the U.S. electricity grid over the past several years.

The federal government has favored fossil fuel development through changes to pollution restrictions, efforts to keep aging power plants operating and investments in gas-fired power plants, pipelines and export terminals. State governments, however, regulate the utilities that deliver electricity and natural gas to customers and have authority over the resources those utilities use.

U.S. Rep. Sean Casten, a Democrat from Illinois, said state regulators have greater authority than federal officials over incentives for connecting lower-cost, cleaner electricity sources to the grid. Regulators also establish interconnection rules and work with regional grid operators that oversee wholesale electricity markets and grid operations.

Data Center Power Demand

Electricity demand from artificial intelligence data centers has affected utility generation plans. Many utilities have delayed coal plant closures and made plans for additional gas-fired power plants as they prepare to serve facilities that require large amounts of electricity.

Opposition to data center development also influenced several election races. Democratic candidates addressed concerns about electricity costs, pollution and the effects of new facilities on residential customers.

Lori Lodes, president of Climate Power, said Democratic governors and governors-elect had treated clean energy requirements as a safeguard against data center pollution. She cited the campaign platforms of Nevada Gov.-elect Aaron Ford, Wisconsin Gov.-elect David Crowley, Acton, Bottoms and Hinojosa.

Lodes said data center development had become an affordability issue for voters and a subject that candidates across several levels of government addressed during their campaigns.

State governments could consider requirements for data centers to use cleaner electricity and address the cost of infrastructure needed to serve them. Such policies could affect electricity procurement, utility investment, and operating expenses for technology companies.

Implications for Energy Companies

The election results give Democrats greater authority over energy policy in several states. The extent of legislative changes will depend on the proposals lawmakers introduce, decisions by utility regulators, and negotiations with electricity providers and project developers.

Renewable energy developers could benefit from new state incentives, clean electricity requirements and permitting reforms. Utilities will have to account for possible changes to generation plans, infrastructure spending and customer rates. Fossil fuel producers could face different regulatory priorities in states where Republicans lost control of state government or utility commissions.

The next legislative sessions will show which proposals move forward and how state governments address electricity affordability, renewable energy development and data center demand. Those decisions will affect energy investment, utility operations and electricity customers across the country.
