Transforming Legacy Fossil Generation Plants with Thermal Energy Storage(PPT)

摘要

Why Build 2,100 GW of New Flexible Resources While Obsoleting 1,100 GW of Coal? 1.Coal Assets not economic operating as balancing resources.2.Flexible resources required for economic balancing.3.Thermal Energy Storage(TES)transforms obsolete assets into high performance balancing resources-at a fraction of the cost of new.Today’s Generation Fleet doesn’t match changing needs.1.Inflexible Generation assets result in renewable curtailment.2.Inflexible Generation is not economic.2.1 Many plants face operating at a loss,or frequently cycling.2.2 Shutdowns increase O&M costs.3.Creates emissions challenges with frequent startups.4.New requirement for assets to be very flexible.4.1 High ramp rates.4.2 Low minimum generation(zero or negative is ideal).4.3 Short start-up time.
