This document summarizes the key challenges facing Britain's transition to lower carbon energy sources. It outlines that electricity demand has fallen while renewables like wind and solar have grown. Policies like contracts-for-difference support renewable expansion but challenges remain around buildings, industry, and balancing decarbonization, security, and affordability. The levy control framework sets spending limits to manage costs but significant barriers persist in deploying technologies like solid wall insulation at scale.

- 9. 9 Low carbon policies are a mixture of UK and EU carbon pricing, regulation and direct support • EU-ETS – Covers 45% of EU greenhouse gas emissions, power sector, manufacturing and now aviation. Prices currently under EUR 7/tCO2e • Carbon price floor – introduced in April 2013 to provide more clarity on carbon price. Current level is £15.70/tCO2e. 2014 Budget capped carbon price support at £18/t from 2016-17 to 2019-20 • Renewables Obligation – RO provides top up on wholesale electricity price. Introduced in 2002 with a 3% obligation on suppliers. It will reach 15.4% in 2015/16. Technology specific ROC bands set in 2009. • Feed-in-Tariff with Contracts-for-Difference (CfDs) – CFDs are seen as a more cost effective than RO and also can also be used by nuclear and carbon capture and storage. • Feed-in Tariffs for small scale generation – supports decentralised generation, e.g, solar PV • Emissions Performance Standards – Annual emissions cap of 450gCO2/kWh for new base- load plants • Industrial Emissions Directive – European Directive that replaces the Large Combustion Plant Directive and cuts SOx and NOx emissions ; places a limit of 20,000 hours on coal power stations which do not invest in flue gas desulphurisation and low NOx burners 2 Transition to a lower carbon energy and greater efficiency

- 12. 12 Proof of concept – eight renewable electricity projects have been offered CfDs 2 Transition to a lower carbon energy and greater efficiency • By 2020, the projects will provide up to £12 billion of private sector investment • The projects could add a further 4.5GW of low-carbon electricity to Britain’s energy mix (or around 4% of capacity) • Once built, the successful projects will contribute around 15TWh or 14% of the renewable electricity we expect to come forward by 2020 and will reduce emissions by 10 MtCO2 per year compared to fossil fuel power generation.
- 13. 13 Security of supply must also be maintained in the low carbon transition • Security of supply is concern with 20% of current capacity expected to retire by 2020 and as intermittent and inflexible generation on system rises • “Missing money” problem is a key problem; prices perceived not to be able to rise to VoLL levels at times of system stress • Capacity Market is being implemented to solve “missing money” problem in energy only market. First auction to be run by end of the year for delivery of capacity in 2018/19. • Pricing under the Capacity Market depends on eligible resources - bidding behaviour by existing coal and gas plants, new gas investment and availability of Demand Side Response • Demand Side Response (DSR) – Capacity market to include eligibility for DSR aggregators, typically for non-domestic interruptible load; challenge in monitoring and verification regime. • Electricity Demand Reduction (EDR) – pilot scheme to test whether additional energy efficiency measures able to play in capacity market. Under development. 2 Transition to a lower carbon energy and greater efficiency
- 14. 14 Capacity margins are projected to tighten significantly without a capacity market Security of supply outlook to 2030 Source: DECC, October 2013 Derated capacity margin • Reliability standard set at LOLE of 3 hours per year, equivalent to a derated capacity margin of ~ 5% • In short term, Supplementary Balancing Reserve to be run by National Grid aimed at existing gas plants, outside of market to prevent mothballing. • Also, transitional auctions for Demand Side Response 2 Transition to a lower carbon energy and greater efficiency
- 15. 15 Energy efficiency and low carbon heat for households and businesses • Energy Company Obligation – requirement on energy suppliers to provide energy efficiency measures to households (loft and cavity insulation, solid wall insulation) • Green Deal for households - government initiative to offer various measures for residential properties at no upfront cost and eventually paid back through energy bills • Commercial energy efficiency schemes – series of measures, including Enhanced Capital Allowances (ECA), Carbon Reduction Commitments (CRCs), Climate Change Agreements (CCAs) • Smart meters – requirement on energy companies to roll out standardised smart meters by 2020 • Regulations – products and policy standards mainly from European Directives Support for low carbon heat • Non-domestic Renewable Heat Incentive – renewable heat tariffs for businesses and public sector organisations to generate and use renewable energy to heat their buildings. • Domestic Renewable Heat Incentive – renewable heat tariffs for domestic consumers, targeted at but not limited to, homes off the gas grid Measures to reduce energy demand 2 Transition to a lower carbon energy and greater efficiency
- 16. Changes to ECO and Green Deal cash-back incentive 16 Deployment of cavity wall insulation Deployment of adequate loft insulation Source: Government’s response to the Fifth Annual Progress Report of the CCC Transition to a lower carbon energy and greater efficiency2 The Government has recently consulted on several changes to the ECO. Major proposals include: • Allow ETT CWI and LI to be delivered under the main ECO carbon target, and reduce this target by 33%; • Increase the eligibility criteria for the carbon target earmarked for low income areas; • Introduce ECO targets for a further two years to 31 March 2017; and • Incentivising delivery to low income and vulnerable households who are off the gas grid. We are currently analysing consultation responses, with a Government Response in due course. Also new incentives for Green Deal Cashback Scheme, e.g. SWI changes from £650 up to £4,000.
- 17. Changes to non-domestic RHI and launch of domestic RHI to improve support & increase uptake Non-domestic • Increased support for renewable CHP, large biomass boilers (over1MW), deep geothermal, GSHP, solar-thermal and biogas combustion • Support introduced for air-water heat pumps and commercial and industrial energy from waste • Updated approach to budget management, tariff certainty Domestic • Launched 9 April 2014 and open to homeowners, private landlords, social landlords and self-builders Projected renewable heat deployed in GB by 2020/21 is 29-59 TWh. 17 Transition to a lower carbon energy and greater efficiency2

- 20. 20 Significant challenges remain on buildings and industry Deployment of solid wall insulation. 2008 – 2022 • Significant technical performance and consumer choice barriers still to be overcome with SWI • Renewable heat tariffs have potential spur deployment of low carbon technologies, but policy instrument still new • The balance between heat networks and decentralised low carbon heat remains uncertain • Experience with deployment of decentralised low carbon heat will be key 3 Challenges Source: Government’s response to the Fifth Annual Progress Report of the CCC
- 21. 21 Balancing decarbonisation, security of supply and affordability is key political challenge • Affordability increasing concern – Energy prices have become a significant political issue in UK and recent steps have been take on ECO and carbon price support to ease the impact of policies on bills • A robust approach to energy efficiency – key to mitigating the impact of lower carbon energy on energy bills of households and businesses • Policies to mitigate fuel poverty and loss of competitiveness of energy intensive industries also central • Economic growth and supply chain – investment, jobs and growth associated with energy infrastructure. Supply chains for offshore wind and new nuclear. • Role of gas in UK market – shale gas and gas generation to back up low carbon generation, but current low spark spreads 3 Challenges
