Gas Prices, Power Prices and Spark Spreads for Major Hubs, Apr. 15, 2026

Why It Matters

Tightening spark spreads squeeze the profitability of gas‑fired power plants, influencing generation mix, investment decisions, and the pace of the energy transition.

Key Takeaways

• U.S. gas price fell to $2.45 per MMBtu
• Power price averaged $45 per MWh across hubs
• Spark spreads narrowed to $38 per MWh, lowest since 2023
• ERCOT and CAISO spreads fell below $30 per MWh
• Renewables supplied 45% of hourly generation, pressuring gas plants

Pulse Analysis

The latest Energy Intelligence snapshot shows U.S. natural‑gas spot prices slipping to $2.45 per MMBtu, a level not seen since early 2024. The dip follows a confluence of factors: robust storage volumes after an unusually warm winter, a modest rebound in LNG exports, and a temporary lull in European demand after the Mideast supply shock. Meanwhile, wholesale electricity prices held near $45 per MWh, buoyed by higher demand in the Northeast and lingering capacity constraints in the Southwest. Together, these dynamics set the stage for tighter spark spreads.

Spark spreads—the margin between power prices and the cost of gas‑fired generation—contracted to $38 per MWh, the lowest reading in the past two years. In power‑dense markets such as PJM and NYISO, spreads remain modestly positive, but in solar‑rich zones like ERCOT and CAISO they slipped below $30 per MWh. The narrowing margin erodes the economic case for dispatching older gas turbines, prompting operators to defer maintenance, retire marginal units, or pivot toward hybrid solar‑gas configurations. Investors are watching the trend closely as it reshapes capacity valuation.

Looking ahead, the sustained pressure on gas‑fired profitability could accelerate the transition to renewable and storage assets. With renewables already accounting for roughly 45% of hourly generation across the studied hubs, utilities are likely to increase battery deployments to capture price spikes and provide firm capacity. Policy makers may also revisit emissions standards and capacity market rules to reflect the evolving cost structure. Market participants that adapt—by enhancing flexibility, leveraging demand‑response, or securing long‑term gas contracts—will be best positioned to thrive in a low‑margin environment.
