ERCOT is considering a support program for the modernization of older energy storage systems
The Texas grid operator (ERCOT) has presented an initial concept for a financial support program aimed at older inverter‑based installations, including energy storage systems and some renewable energy assets. The goal of the initiative is to improve grid stability by encouraging asset owners to upgrade their control systems.
The program is currently in the conceptual phase and was outlined in a working document published in March 2026. It proposes a mechanism of one‑time financial incentives for entities that decide to implement so‑called advanced grid support capabilities.
Modernizing older installations as a prerequisite for system stability
The proposal focuses on installations connected to the grid before the introduction of newer technical requirements. Many of these assets use grid‑following technology which—unlike more advanced grid‑forming solutions—offers limited capabilities for stabilizing the power system.
The modernization would enable:
- improved response to frequency and voltage disturbances,
- implementation of functions that support grid stability,
- better alignment of older units with current technical standards.
Financial incentives and participation criteria
According to the concept, program participants would be eligible for a one‑time payment based on the installed capacity of the upgraded asset. The total program budget and detailed support conditions remain at the proposal stage and may change as work progresses.
Participation would be voluntary and targeted at owners of installations not covered by the latest requirements for advanced grid‑support functionalities.
Next regulatory steps
ERCOT plans further consultations with market stakeholders before potentially submitting a formal request to amend operational protocols. Publication of such a request is expected in the second quarter of 2026.
If the proposal is further developed and approved, the program could become one of the tools supporting the technological transformation of older assets and strengthening the resilience of the Texas power system.
