There are two type of filings: Annual filings (filed on or around October 31st) and Monthly filings (filed 45 calendar days prior to the compliance month). Commission staff evaluates LSE filings annually and monthly to ensure accuracy and completeness.
For the annual filings, LSEs are required to make an annual System and Flexible compliance showing for the coming year. For the System showing, each LSEs is required to demonstrate that it has procured 90% of its System RA obligation for the five summer months of the coming compliance year. Additionally, each LSE must demonstrate that it meets 90% of its Flexible RA obligation for all twelve months.
For LSEs in the San Diego local distribution area only, each LSE has a three-year forward local obligation and must meet 100% of its local requirement for the years one and two and 50% of for year three.
For the monthly filings, LSEs must demonstrate they have procured 100% of their monthly System and Flexible RA obligation. Additionally, on a monthly basis from July through December, LSEs in the San Diego local distribution area must demonstrate they have met their revised (due to load migration) local obligation. LSEs in SCE and PGE local distribution areas are no longer required to demonstrate 100% local RA compliance as the Central Procurement Entity assumed responsibility for local in those areas as of 2023 compliance.
