In response to market and regulatory needs, ERCOT manages a variety of projects each year. ERCOT's ongoing Project Priority Planning Process ensures that projects are prioritized as part of the transparent system of governance. Proposed Revision Requests are reviewed by the Protocol Revision Subcommittee (PRS). If approved at PRS, the Revision Request proceeds to the Technical Advisory Committee (TAC) and then to the Board for final review and approval. The ERCOT budget is approved every two years. To ensure fiscal responsibility, the ERCOT budget, which includes funding to support project activity, is reviewed by the Finance and Audit Committee and approved by the ERCOT Board.
