4. USA COMPETITIVE SERVICES COMPETITIVE SERVICES Order 755, “Frequency Regulation Compensation in the Organized Wholesale Power Market,” requires regional transmission organizations (RTOs) and independent system operators (ISOs) to adopt a two-part market-based compensation method for frequency regulation services A capacity payment reflecting opportunity costs A market-based performance payment (This payment rewards faster-ramping resources) Studies run by DNV KEMA illustrated that fast ramping resources have a 3X effectiveness in providing regulation services The graph to the right illustrates the ability of fast ramping resources (bottom right) to follow AGC (Automated Generator Control – 2s signal) while a slow ramping generator unit is unable to accurately follow the ramp signal (top right).

National Development Network Development Plan 2015 Emerging Technologies Information Paper AEMO’s initial modelling of the impact of battery storage, electric vehicles and fuel switching in the 20- year NEFR outlook period. Modelling battery storage: no mechanism for tracking the number of installations in Australia. AEMO has developed the first step of its economic model to estimate the uptake of battery storage systems by residential consumers
