NERC recently published a reliability assessment of the final Clean Power Plan rule – Potential Reliability Implications of EPA’s Clean Power Plan – Phase II. The report finds that combined wind and solar capacity will rise by 10-20 GW over the next 15 years, while coal capacity will decline by up to 27 GW as a result of the CPP. The accelerated transition in the mix of generation resources means a greater emphasis on how renewables and other resources provide essential reliability services – voltage control, load ramping and frequency response. On Wednesday, June 22^nd, from 10 to 11 a.m., John Moura, NERC’s Director of Reliability Assessment and System Analysis, will provide an in-depth briefing on the NERC report.
