Balancing Up Load (BUL) & Controllable Load Update PUCT DR Workshop
Update of BUL Program PUCT DR Workshop
Balancing Up Load (BUL) • What is a BUL? • A portfolio of ESI-IDs that can be bid into the Balancing Energy Market to provide Balancing Energy Up Service • Bids are submitted as a BULBES bids and cleared in the same stack with other UBES bids (generation) and LAARBES bids (LaaR) • Upon successful deployment, QSE is paid: • MCPE in the form of a Resource Imbalance payment • MCPC for NSRS (if Nonspin market open for deployed intervals) PUCT DR Workshop
Balancing Up Load (BUL) • BUL was implemented on October 29, 2003 (PIP-112) • Since implementation no loads have registered to participate as a BUL What happened? PUCT DR Workshop
Balancing Up Load (BUL) Reasons for lack of participation vary, but comments received include: • Typical NSRS payment is too low to justify the effort & subject the load to ERCOT dispatch (vs. voluntary load response) • Balancing Energy prices too low, or subject to post-mitigation • Price uncertainty due to MCSM • Determination of compliance with the deployment instruction is too complicated • Contracting with potential clients is difficult since performance is determined on a portfolio basis and not an individual ESI-ID basis PUCT DR Workshop
Balancing Up Load (BUL) Current Status: • No consensus within the stakeholder process to modify the program • Implementing any changes would need to receive funding through the TAC Project Priority List (PPL) process • BUL (or similar program) does not exist in the Nodal Protocols, making significant or costly changes difficult to justify PUCT DR Workshop
Update of Controllable Load Pilot PUCT DR Workshop
Controllable Load Pilot Update Background: • PUCT Staff requested ERCOT to investigate implementing PRR307 (Controllable Loads) • To fully implement PRR307 it was estimated to cost $500K to $1MM and take up to a year to migrate into production. • ERCOT proposed an alternate solution which would utilize existing code but with some limitations. ERCOT also suggested this option be tested on a pilot basis. PUCT DR Workshop
Controllable Load Pilot Update • Controllable Load Pilot was initiated on October 7, 2006, following a thorough qualification test of the load • Pilot will extend for 90 days (thru January 4, 2007) • At the conclusion of the pilot ERCOT and PUC Staff will evaluate the results and make a recommendation concerning opening the program up to other qualified participants PUCT DR Workshop
