Texas Staff File Draft Proposal For Adoption For Changes To Reliability Must-Run (RMR) Rules
August 25,2017
Staff of the Public Utility Commission of Texas have filed a draft proposal for adoption concerning changes to the Reliability Must-Run (RMR) service rules
The draft proposal for adoption includes the following provisions:
• Requires notice of the intent to suspend operation of a generation resource 150 days prior to the intended suspension date [currently only 90 days notice is required]. However, for seasonal mothballing, the current 90 days notice would be maintained, in a change from an earlier proposal. Additionally, the draft proposal for adoption drops the proposed requirement for resource owners to submit a budget for providing RMR service with their notice.
• Allows ERCOT to consider the economic value of the incremental reliability provided by an RMR or Must-Run Alternative (MRA) service agreement by incorporating the value of lost load into its analysis. The amendments allow ERCOT to decline to enter into an agreement based on its evaluation.
• Requires ERCOT governing-board approval of all RMR or MRA service agreements, as well as any ERCOT Staff recommendation to forgo an agreement if a reliability need is present.
• Requires refund of payments made to resources to facilitate capital upgrades related to RMR or MRA service if those resources return to the market after the conclusion of the RMR or MRA service agreement.
