5
Making Clean Local Energy Accessible Now 5 Flatten the Duck – Curtail Baseload Generation Rather than address over-generation with more natural gas generation, California can strategically plan maintenance on baseload plants during shoulder months. Source: CAISO Summer Loads and Resources Assessment CAISO planned outages ranged up to 7000 MW per weekday in the summer of 2012.

Making Clean Local Energy Accessible Now 17 Natural Gas Plants Have Integration Costs Renewables have predictable variability. Fossil fuel power plants often shut down unexpectedly, forcing energy consumers to foot the bill for reserves and frequency response. Source: CAISO Summer Loads and Resources Assessment More than half of the outages associated with conventional generation are unplanned.
