6. The Changing UK Energy Market What does this mean? ~75GW Increasingly digital Increase in urban population 15% generation low carbon Regulation to support energy efficiency Carbon pricing ~110GW Today‘s Energy Market Tomorrow’s Energy Market Backup generation becoming more important & valuable 8 GW reserve Generation – 7% 9 GW Coal Retirements 37 GW of renewables on line Residential bills will double Significant coal power plants Predictable demand Low levels of renewable generation 4 GW reserve Generation – 5%

11. Business Benefits Summary - CHP CCHP – Combined Cooling Heat & Power – 4 year payback Reduced Energy OPEX Reduced CO2 Reduced Risk Increased Security CCHP: coolth, heat & electricity Energy costs typically 20% Asset payback is now < 4 yrs Guy’s & St Thomas’ (6MW): £1M/pa savings Savings may increase with new government policies around CHP Exposure to rising energy prices Guy’s & Thomas’ savings increased by 30% in last 3 years Assuming energy prices rise faster than interest rates, economics continue to improve >85% efficiency: reduces C02 Hot water and building heating provided from waste heat, absorption chillers create cooling Assuming 1 MW: annual CO2 reduction –1k tonne Key part of Government Energy Policy for decentralised energy GE Confidential - Distribute to authorized individuals only. Community facilities & developments CCHP becomes primary source, grid secondary, significantly reducing risk of delays from DNO outages

14. What is STOR? Harnessing existing back up assets to generate new income Short Term Operating Reserve (STOR) This is the provision of additional active power from generation provided by ‘Asset holders’ who have installed standby capacity. Asset Holders – Capacity …are paid for making their generating capacity available to the National Grid Asset Holders - Generation …are also paid when the generation is utilised by the National Grid (at times of peak load, or where traditional generation has failed). Examples are any industry with currently installed standby generation – eg – water utilities, hospitals, banks, data centres, farming… Aggregator GE Energy manages the aggregation of multiple smaller generation providers (Asset Holders) into 3MW lots which are required by NG.

15. Why is STOR required? Less Predictable Generation & Changing Demand Challenges ScenarioSTOR Hot sunny day, air conditioning on maximum England are in the World Cup Final Emergency mtc -1 GW generation goes off line Grid reserve capacity is now critical Asset Holders spare backup generation sits available Grid sends signal to generation Generation comes on until it is not required Backup generation goes back into standby mode New inflexible generation, wind & solar Changing demand patterns from Electric Vehicles Changing customer behaviour Increasing demand for power
