Secure Supply

What frame work is essential that the electricity sector is sufficiently contributing to the CO2- emission reduction?

How do we ensure a sufficient capacity of flexible/ predictable supply capacity as back up for fluctuating renewables?

Afford-able

Target of the Energy Supply Sector remains unchanged, however questions to be addressed properly

• German Government creates pre-conditions for CHP promotion by „KWK Gesetz 2009 / 2012”

Consequences and Figures for high Efficient CombinedCycle Power Plants > 2MW (KWKG 2012)

• Increase of promotion for CHP from 1.8 ct/kWh up to actual 2.1 ct/kWh KWK-Power

• Retention of the max. promotion volume of 750 Mio EUR/year

• Abolition of the max. promotion period of time (6 years) andintroduction of a promotion limit of “30,000 full load operating hours”

• Introduction of promotion mechanism for heat- and cooling storage

The latest generation of CCPP are a key element for keeping the balance in the power supply system

Market challenges: Fluctuating feed-in and oversupply of renewable power Decreasing operating hours on fossil plants Highly flexible fossil units have to stabilize the grid

Our answers: Highest efficiency CCPPs to reduce fuel costs and CO2

CoGen / CHP design with max. utilization of heat and power Design for Flexibility (daily start-stop, shortest startup times, high ramp rates) Full grid code compliance for todays and tomorrows requirements

!

But ! Market must pay for what is needed Maintain an affordable balance between incentives, CO2-charge and market power Keep triangle of power generation: affordability, sustainability, reliability in balance
