The document discusses the transition to a post-subsidy energy market and the challenges of creating a low-carbon power environment, highlighting the role of grid operators. It outlines the advantages and disadvantages of current subsidy mechanisms, and emphasizes the importance of optimizing decentralized energy systems and enhancing cooperation between transmission and distribution system operators. The conclusion encourages collaboration in research and innovative projects to navigate the evolving energy landscape.

- 1. Life in a post subsidy energy market, and the impact of grid operators actions on trying to create a low carbon power environment Low Carbon Innovation in Energy Systems Bath Innovation Centre July 2018
- 2. Ecotricity • Renewable energy company • Supplies > 200,000 energy accounts • >80 MW of onshore wind • ~1MW of solar PV and 700 rooftop installations • All of it is in receipt of some form of subsidy… • Electric vehicle charging • Manufacture of small wind • Vegan football club • Energy storage • Grid • Business • Home • Green Gas • Wave and Tidal • Smart Grid…
- 3. Subsidy – ROCs, FiTs and CfDs The Good: • ROCs provide support to anyone who meets the requirements • FiTs provide known revenue for the life of the project • CfDs provide a fixed price for 15 years The Bad: • But revenue is uncertain and fluctuates • But tariff degression rules cause the market to lurch • But infrequent auctions and limited budgets make it difficult to access The Ugly: • Always at risk of Government intervention • Perceived high costs are used to damage public opinion Subsidy free world presents new challenges but free of baggage
- 4. Post Subsidy World One approach… • Try to make more impact from a smaller investment • Efficiencies and better use of existing infrastructure • E.g. distributed energy is now a significant part of the grid, but is it being optimised? • Imitate success of social media?
- 5. Smart Grid • Launched Partnership with Next Kraftwerke in May 2018 • Taking decentralised units (our own and 3rd party) and connecting them • More efficient dispatch • Services to the network
- 6. Grid Operators – TSOs and DSOs • 7 different parties to offer services to • Network wide services vs. location specific services • Challenging incumbents and monopolies to level playing field EBS
- 7. Network wish list 1. Co-ordination between TSO and DSOs • Compatible services that don’t solve a TSO problem but then cause a DSO problem or vice versa. • Joined up procurement of services over same periods and tender dates. 2. Sign posting for where support is needed 3. Equitable treatment between single large power plant and distributed units • Open Networks Project • UKPN and WPD flexible services and power • Project TERRE
- 8. Conclusion… What can be done? • Interest in optimisation • Early engagement • Collective influence Or more specifically… • Join our Smart Grid! • Partner with us in research projects? • Approach us with brilliant ideas
