ERCOT CEO Pablo Vegas has said the proposed batch system will give developers a clearer indication as to when they can connect to the grid.
________________________________________________
Struggling to keep up with a flood of grid interconnection requests from data centers and other large load industries, ERCOT has begun developing a program to consider the requests in batches.
However, program rules won’t be complete for at least four months, according to the Public Utility Commission.
THE PROBLEM
As one of its primary responsibilities, ERCOT, also known as the Electric Reliability Council of Texas, examines all new interconnection requests from large load industries to ensure the grid will have sufficient transmission capacity to serve them. But, because of the influx of new data centers and other large loads seeking grid connections, ERCOT now has a hard time keeping up. Traditionally, ERCOT efficiently can handle eight to 15 such requests during any given quarter. Now it receives 80 to 100 requests over the same period, and these new requests come from much larger loads, according to reports.
Moreover, many large loads under the current system have found themselves locked in a “doom-loop” — that is, a situation wherein their potential impacts on the grid face repeated reevaluations from ERCOT because of potential offsetting impacts from nearby loads also seeking interconnections.
ERCOT CEO Pablo Vegas has said the proposed batch system will address these problems and likewise give developers a clearer indication as to when they can connect. More specifically — after a batch study is complete, each proposed load in it will have 30 days to make a financial commitment. If the proposed load makes this commitment by the deadline, a corresponding amount of grid capacity will be “reserved” for the project in all future studies.
Mr. Vegas has said this batch study process replaces Planning Guide Revision Request 115 Interconnection Requirements for Large Loads and Modeling Standards for Loads 25 MW or Greater, which was designed to more formalize the study process supporting the interconnection of Large Loads.
INDUSTRY CONCERNS
Industry officials and other interested parties appear to universally support the “batch process” in principle, although many have concerns about its implementation. For instance, Cameron Poursoltan, a data center trade group analyst, has said that some projects have waited years for interconnection despite meeting all relevant criteria. He said his coalition wants to ensure that these in-limbo projects won’t be disadvantaged, according to his comments reported by media outlets.
Another question is whether ERCOT should kick off the first batch study ASAP under the assumed rules or whether ERCOT should wait until the fall.
ERCOT officials have said guidelines to determine “Batch Zero” project eligibility will be sorted out during upcoming stakeholder workshops as noted below. Because the final rules will determine winners and losers, stakeholder participation in the rules proceedings remains high. The Steering Committee of Cities Served by Oncor also is participating in this stakeholder process.
TIMELINE
ERCOT presented a framework for studying the issue to PUC commissioners during a Feb. 20 open meeting. ERCOT also hosted several workshops on the proposed rules (including one on Feb. 26) and will hold more through May.
Meanwhile, ERCOT’s Technical Advisory Committee, a stakeholder group, will receive monthly updates on the process and is expected to vote on new rules on May 12.
An ERCOT board vote is expected on June 1, with the new rules projected to take effect on Aug. 1.
