Current main driver: micro-CHP
Micro-CHP as a transition technology:• Current rollout schedule (units/yr)• Price 6000 Euro ->>> 2500 Euro in five years; i.e. 5 years payback time

Field test Results; load distribution
• In a summer situation (May 2007), the substation peak load is reducedby 30%. In winter, the reduction is 50%. Increase of thermostatbandwidth by 0.5 degr. suffices
• A conventional “fit-and-forget” control strategy does not reduce thesubstation peak load.
