Today’s LiveWire Spotlight is on NERC’s interpretation of TPL-002-0, which has ignited a major dispute between FERC and several industry Trade Associations. FERC has rejected the interpretation proposed under Project 2009-14 that a Protection System misoperation is only a multiple contingency event addressed by TPL-003-0 or TPL-004-0 – but must also be considered a base case under a single contingency scenario.
