As the integration of large-scale wind and solar energy accelerates, the necessity for frequency regulation services becomes critical for maintaining grid stability. Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs) leverage these services to balance supply and demand and correct frequency deviations, ensuring reliable operations. With the rise of renewable energy, regulatory capacity requirements are projected to double as renewables reach higher penetration levels. By 2015, the U.S. electricity market is estimated to need around 16 GW of frequency regulation capacity, highlighting the growing importance of these services in the transitioning energy landscape.

SMART GRID with FREQUENCY REGULATION SERVICES
FREQUENCY REGULATION SERVICES • Large scale integration of wind and solar generation will affect physical operation of the grid. A key area is the increasing need for frequency regulation.
WHAT IS REGULATION SERVICES? • Frequency regulation is a tool that regionaltransmission organizations (RTOs) and independent system operators (ISOs) use to balance supply and demand on the transmission system to correct frequencydeviations thus maintaining reliable operations. • Frequency regulation services is the highest paid Ancillary Service. • FERC Order 755 will have revenue enhancing impact for storage resources providing frequency regulation.
FREQUENCY REGULATION MARKET SIZE • Regulation services capacity in the electricity markets is typically sized based on the predicted daily peak/valley load. • 7600 MW of frequency regulation capacity is estimated as the requirement today in the US (based on 1% of Energy Information Administration’s (EIA) estimate of 2011 summer peak load). • As intermittent, renewable generation levels rise to 20%, frequency regulation capacity requirement is expected to rise to double to about 2% of peak/valley load. • This will rise even further to approximately 4% should renewable penetration levels reach 33%. • Using EIA’s forecasts, and 2% of peak load as a guide, US electricity markets will require approximately 16 GW of frequency regulation capacity by 2015. • Global regulation capacity is estimated at 37 GW to 75 GW depending on the level of renewables penetration.
