Why choosing Adiabatic Compressed Air? Back in 2008 Pumped Hydro Storage looked very prosperous > Typical operational schemes switched from classic day-night-cycles to short and frequent operation patterns > The RES directive (2009/28/EC) fixed RES goals by country, hence technical storage potential could be determined, especially steep RES introduced ramping The identified first estimation of storage potential indicated that The identified first estimation of storage potential indicated that available PHS potential would not be fully sufficient > RWE was involved in the European AA-CAES project and convinced of the technology > Adiabatic CAES seemed natural follower to PHS since: – Theoretical efficiency of 70% was closest to PHS, even comparable with old plants – Potential German sites were close to wind generation centers in the north – CAPEX was expected to come close to PHS with larger scale deployment RWE 7/4/2013 PAGE 3
Central Storage is macro-economically useful, but faces micro-economic pressure due to market and regulation > Market evolution did not reflect the Reference CASE Germany estimated need of flexibility Since 05/2013: Incentive for residential sufficiently in any bulk market batteries limiting PV feedings to 60% > Present energy only markets do not German EEX-Spot Market Prices 2011 produce any business case for any 100,00 new-built storage 90,00 2030 with 2030 with > Consequently storage roll out is 80,00 new incentive? No-PV-Age limited. Hence CAPEX-decline for A- 70,00 CAES will be smaller as expected. 60,00 [€/MWh] Today 50,00 > Yet, maximising social economic 40,00 benefits central storage is still option 30,00 of choice, but only after 2030 20,00 2030 w/o any 10,00 > Current regulation focuses on intervention? 0,00 local remedies, not on the system 19.07 19.07 19.07 19.07 20.07 00:00 06:00 12:00 18:00 00:00 Even demos must fully optimise economy!
