Trump calls wind, solar bad for power grid. Texas shows otherwise

President Trump's claims that renewable energy destabilizes the U.S. power grid and increases costs are challenged by the performance of Texas's ERCOT, which has achieved dramatic reliability improvements—reducing blackout risk to 0.30% from 12%—and electricity prices 24% below the national average, largely due to significant battery storage integration. This contrasts with fossil-fuel-heavy grids like PJM, which are experiencing rising costs and projected reliability declines, suggesting that proposed subsidy cuts for renewables could exacerbate grid instability and energy inflation rather than improve it.

Analysis

The performance of the Texas power grid (ERCOT) directly challenges the administration's assertion that renewable energy undermines grid stability and inflates costs. Contrary to these claims, ERCOT, the U.S. grid with the most renewable energy, has seen a dramatic improvement in reliability, with the forecasted chance of rolling blackouts in August dropping from 12% to just 0.30%. Concurrently, electricity prices in Texas are 24% below the national average. This enhanced stability and cost-effectiveness is largely attributed to the rapid integration of nearly 5 gigawatts of new battery storage since mid-2024, a capacity set to expand significantly. In stark contrast, the PJM Interconnection, a grid heavily reliant on fossil fuels (nearly 60% from gas and coal), is experiencing soaring electricity prices and faces a U.S. Department of Energy projection of substantial blackouts within five years. This data suggests that the administration's policy of ending renewable subsidies may be based on flawed premises and could, according to cited experts, risk exacerbating the very price and reliability issues it claims to solve.

Key Decisions for Investors

• Given the demonstrated success of the ERCOT grid model, investors should assess opportunities in companies specializing in utility-scale battery storage and solar generation, as this combination is proving critical for enhancing grid reliability and managing costs.
• The projected price increases and reliability shortfalls in the fossil-fuel-heavy PJM grid represent a cautionary signal for utilities with high exposure to coal and natural gas generation, warranting a portfolio review for assets in regions lagging in renewable integration.
• The administration's policy to terminate renewable energy subsidies introduces significant regulatory uncertainty; therefore, investors should closely monitor the project economics and balance sheet strength of renewable developers who have historically depended on federal tax credits.
