Data retention - The BA, GO, and GOP shall keep data or evidence to show compliance, as identified below, unless directed by its Compliance Enforcement Authority to retain specific evidence for a longer period of time as part of an investigation. Compliance audits are generally about three years apart. • The BA shall retain a list of identified Frequency Measurable Events and shall retain FME information since its last compliance audit. • The BA shall retain all monthly PFR performance reports since its last compliance audit. • The BA shall retain all annual Interconnection minimum Frequency Response calculations, and related methodology and criteria documents, relating to time periods since its last compliance audit. • The BA shall retain all data and calculations relating to the Interconnection’s Frequency Response, and all evidence of actions taken to increase the Interconnection’s Frequency Response, since its last compliance audit. • Each GOP and GO shall retain evidence since its last compliance audit.
