Executive Summary

• ERCOT’s total installed capacity could grow by 87% by 2050, with solar reaching 113 GW and battery storage expanding 6.5x to 45 GW.
• Coal generation is projected to be nearly eliminated by 2041, while natural gas capacity rises by 6 GW, driven by flexible open-cycle gas turbines.
• Wholesale power prices could peak around 2040, before declining by 2050 - as demand growth slows and renewables expand.

Introduction

ERCOT’s power grid is evolving - fast. Developers are rapidly building newer technologies, such as solar generation and battery energy storage systems, to meet growing demand. In fact, in the past year alone, installed solar capacity has grown by ~8 GW, or 44%. Meanwhile, the total installed rated power of battery energy storage has increased by ~2.5 GW, or 82%. And there’s no sign of buildout slowing down in the next few years.
