N2 - Through a systematic development of the Danish electrical supply system with wind power and CHP, problems with stability and electricity surplus have appeared. Therefore, the possibilities for profitably implementing a CAES plant for energy storage, peak shaving and electricity surplus reduction are investigated. Based on existing plants and the latest technology a simulation model of a 360 MW plant with an efficiency of 35 % has been developed and optimized to Danish conditions. An analysis of the economics in the plant, operating under market conditions, shows a growing potential, but the allocated investment costs require investigation of more competitive operation. The regulating-power market could be a solution.
