RTO Generators’ Reliance on IT or Released Capacity

Non-RTO Utilities “[For Southern Companies’ gas-fired resources] sufficient amounts of firm gas transportation and storage capacity are maintained for the reliable operation of such facilities when needed to satisfy system demand.” Comments of Southern Companies, Docket No. AD12-12, at 2.

Non-RTO Pipeline Capacity Sharing
Commission accepted contract under which Southern Company Services, as agent, purchased transportation capacity it could share among various operating entities: “the Commission agrees with the assertions of Southern that such an arrangement is convenient for the affiliated utilities which are jointly and severally liable for the demand charges of Southern …” Southern Natural Gas Co., 123 FERC ¶61263 (2008)

Effect on Generation Availability
PJM reported to the Commission: Pipelines issued operational flow orders so IT shippers could not nominate. Pipelines issued notices affirming the restriction of customers to their hourly schedules and the penalties that would apply if they went over their ratable amounts. Reduction in supply from the Marcellus due to the cold weather. As such, gas availability for power generation was tight over the entire footprint. January 10, 2014 report

Recent Commission Waivers
Granted PJM waiver of OA to permit communication with pipelines pursuant to Order No PJM, 146 FERC ¶61,003 (2014) Granted PJM and NYISO waivers to permit make-whole payments for generators with costs greater than offer cap. PJM,146 FERC ¶61, ), NYISO, 146 FERC ¶61,061(2014). Granted PJM Temporary Waiver of $1,000 Offer Cap for cost-based generator offers. PJM, 146 FERC ¶61,078 (2014).

PJM Uplift Charges PJM IMM reports $630 million in uplift charges for January 2014 alone. Market Monitor Report, (Feb. 24, 2014). $74 million is Day-Ahead and Real-Time lost opportunity costs. $392 million due to conservative operations IMM Issues to be addressed: Improve incorporation of conservative operations into pricing Gas/electric scheduling/commitment.
