Solar and other renewable energy shares rose on Wednesday 4 November after Democrats won control of both the Senate and the House in the US midterm elections, as investors bet on a more supportive policy environment for clean energy.
Canary Media said Democrats "won big-time on the national level". The results also brought Democratic gains in state governments and utility commissions that could matter directly for solar and storage.
How the markets reacted
In US pre-market trading, First Solar rose by around 8%, according to both PV Tech and Investing.com. PV Tech reported Sunrun up around 7%, Canadian Solar up more than 7%, T1 Energy up 11% and Enphase up 4.1% at the time of writing. Investing.com had Sunrun up 8.6%.
In Europe, Investing.com reported SMA Solar up 11.6%, Nordex up 8%, Vestas and Orsted up between 5% and 7%, EDP Renovaveis up about 4% and Voltalia up nearly 6%. In Asia, South Korea's Hanwha Solutions closed 18.6% higher, while HD Hyundai Energy Solutions and OCI Holdings gained 12.5% and 10.4%. Investing.com said renewable stocks were also benefiting from a rotation away from shares tied to artificial intelligence.
"Energy affordability was a key issue in this election, reflecting the real pressures facing American households and businesses," said Tim Pawlenty, CEO of the Solar Energy Industries Association (SEIA). "The solar and storage industry looks forward to working with newly elected federal and state leaders to bring more affordable, reliable power online and deliver the energy savings Americans are demanding."
Georgia's regulator changes hands
One of the most direct results for solar came in Georgia, where Democrats Shelia Edwards and Peter Hubbard won both Public Service Commission races. That gives their party a 3–2 majority on the utility regulator for the first time in decades. Canary Media noted that SEIA had spent money to promote those candidates.
In Texas, Democrat Jon Rosenthal won a seat on the all-Republican Railroad Commission, which oversees the state's oil and gas industry. Utility boards in Alabama, Louisiana, Nebraska, North Dakota, Oklahoma and South Dakota stayed in Republican hands, and the commission races in Arizona and Montana had not been called by Wednesday afternoon.
New Democratic trifectas
Come January, Michigan, Minnesota, Nevada, Pennsylvania, Wisconsin and likely Arizona will have Democratic trifectas, meaning control of the governor's office and both chambers of the legislature. Nevada and Arizona are among the top solar developers in the country, and Arizona is rising in the rankings for battery storage. Democrats have not controlled the Arizona legislature for 60 years.
Data centres on the ballot
Power demand and local opposition to data centres also featured. Voters passed or leaned towards passing 33 measures restricting data centre construction in their communities and approved only one measure supportive of the facilities, according to Stateline, as cited by Canary Media. Analysts quoted in Canary's coverage expect Democrats to focus on energy affordability and restoring clean energy tax credits with their new congressional majority.
What it means for the Americas
The new Congress does not change federal policy overnight, and any new legislation will still need the president's signature. But the market reaction shows investors pricing in lower political risk for solar and storage across the supply chain. At state level, the results in Georgia, Arizona and Nevada could shape how utilities plan and procure new solar and battery capacity in the years ahead.
