Overview of Electricity Market Reform Matthew Taylor Head of Strategy and External Relations Low Carbon Contracts Company

Overview of Electricity Market Reform Aim of Electricity Market Reform Roles and responsibilities Description of the main instruments Contract for-difference Capacity Market Role of the Low Carbon Contracts Company Key Timings https://lowcarboncontracts.uk/

What is the aim of Electricity Market Reform Aim of Electricity Market Reform Ensure secure electricity supply through having sufficient capacity to meet demand, a diverse portfolio of generation technologies and a reduced reliance on fossil fuels. Ensuring sufficient investment in sustainable low-carbon technologies to provide the necessary support and stable revenues to decarbonise electricity generation. EU 2020 renewables target and to reduce carbon emissions by at least 80% of 1990 levels by 2050. In a way which maximises benefits and minimises costs to the UK economy and to taxpayers and consumers. https://lowcarboncontracts.uk/

Roles and Responsibilities There are a number of roles and responsibilities Low Carbon Contracts Company & Electricity Settlements Company: CFD Counterparty manages CFDS, Supplier Obligation, CM Credit Cover EMR Settlement Ltd Manages settlement operations on behalf of LCCC National Grid (Delivery Body) Runs application, allocation and auction processes for CFD and CM DECC Sets policy for EMR: Allocation Framework for CFD, Auction rules for Capacity Market Ofgem Monitor costs of Delivery Body and disputes role https://lowcarboncontracts.uk/

Description of the main instruments The main instruments to achieve these objectives are Contract for Difference (CFD) Capacity Market (CM) Carbon Price Floor Electricity Demand Reduction https://lowcarboncontracts.uk/

CFD The CFD framework is designed to provide revenue stability Attract a wider pool of capital sources Allows investment to come forward at a lower cost of capital Introduce competition as a conduit for cost reduction Delivery of a range of technologies https://lowcarboncontracts.uk/

CFD The CFD framework consists of a number of components The contract itself the CFD The Supplier Obligation which regulates payment flows between the consumer and the generator The Allocation Process Regulatory underpinning the Energy Act 2013 and supporting legislation and regulation https://lowcarboncontracts.uk/

CFD The CFD is a private law contract Defines rights and obligations between the generator and the counterparty (the Low Carbon Contracts Company) Provides a number of protections for the generator to protect against erosion of value over the term of the contract including: Change in law Indexation Force majeure Dispute resolution process Other mechanisms to preserve value https://lowcarboncontracts.uk/

The Supplier Obligation allows for payments between the consumer (supplier) and generator CFD Obligation on electricity suppliers to make payments to the LCCC Obligation periods quarterly, commencing from 1 April 2015 Supplier Obligation payments cover: Suppliers Supplier Obligation Levy Funds the payments to generators Interim levy Reconciliation amounts Reserve payment Suppliers Reserve Payment Amount prepaid by suppliers to provide LCCC with sufficient funds with 95% confidence Other contingency provided through credit cover (cash or LOC) Mutualisation payments Credit Cover Suppliers Operational cost levy Funds the ongoing operating costs of LCCC and ESC Funds own capex through depreciation charge https://lowcarboncontracts.uk/

Whilst the Allocation Process is the mechanism by which developers compete for a CFD CFD Governed by the Allocation Framework DECC defines eligible technologies and sets the administrative strike price Last allocation round had three pots Pot 1: onshore wind, solar, energy from waste CHP, hydro, landfill gas, sewage gas Pot 2: offshore wind, tidal stream, wave, ACT, dedicated biomass with CHP, geothermal Pot 3: biomass conversion https://lowcarboncontracts.uk/

CFD The allocation process drives competition in order to reduce costs to consumers Application Generator applies to Delivery Body, can request minor and necessary changes Valuation Delivery Body values total number of qualifying applications Qualification Delivery Body checks qualifications Sealed Bids If valuation is above set level (driven by LCF etc.) then sealed bid auction commences Review Review of applications Allocation Post auction Delivery Body allocates CfDs Appeals Generator can appeal any decisions made by Delivery Body on application qualifications Notification Delivery Body notifies LCCC. LCCC offers CfD https://lowcarboncontracts.uk/

CFD Outcomes of the first allocation round were positive with a mix of technologies TECHNOLOGY MW Advanced Conversion Technology 62 Energy from waste 94.75 Onshore wind 748.55 Offshore wind 4346 Solar PV 38.67 Biomass with combined heat and power 299 https://lowcarboncontracts.uk/

CFD And with a lower cost to consumers Competition seems to have delivered lower cost to consumers when compared with Renewables Obligation Allocation Round delivered 2.1GW at price lower than ASP And lower than had the capacity been supported under the RO Source: Independent Evaluation of the Electricity Market Reform, Grant Thornton and Pὅry, October 2015 https://lowcarboncontracts.uk/

The Capacity Market

Capacity Market The Capacity Market Is designed to ensure sufficient, reliable capacity in periods of system stress Gives eligible capacity providers reliable revenue stream Capacity providers face penalties if fail to deliver capacity when required Philosophy is to allow the market to competitively set the price for capacity Agreements are offered to providers of existing and new capacity four years ahead of when the capacity is required https://lowcarboncontracts.uk/

Forecasting the Supplier Levy Andrew Miller Head of Forecasting Low Carbon Contracts Company

Agenda 1. Introduction Meet the team Overview of Supplier Obligations Overview of LCCC Forecasting Team 2. More about the Supplier Obligation 3. The Transparency Tool 4. Key dates 5. Longer Term Outlook https://lowcarboncontracts.uk/

Introduction to the team Andrew Miller Head of Forecasting 20+ years in electricity industry MSc Renewables & PhD plasma physics Harold Anuta, Forecasting Analyst PhD candidate in energy storage Industry consultancy background Emily Lewis, Forecasting Analyst MSc in finance Previously at Centrica mid and downstream roles https://lowcarboncontracts.uk/

Introduction: Overview of Supplier Obligations Contracts for Differences are a key part of Electricity Market Reform designed to support low carbon generators Paid for by a levy on suppliers Based on initial payments (reserve and interim rate) and later reconciliations Rate set quarterly, 3 months in advance, with ability for LCCC to raise in period adjustments if required Credit requirements (cash or letter of credit) Supplier payments: Interim levy rate & Reserve payments Supplier levy reconciliation LCCC Payments to generators with CFDs Note in some cases generators pay us https://lowcarboncontracts.uk/

Introduction: Role of Forecasting 1. Regulations require we set an Interim Levy Rate and Total Reserve Amount each quarter, at a level giving a 19 in 20 confidence that LCCC will have sufficient money to pay 2. Regulations therefore imply we must make probabilistic forecasts taking into account the uncertainties regarding CFD payments 3. Also need to take into account the flow of cash considering the payment timing 4. We need to continually re-forecast within period to check we are still likely to be able to pay 5. We also plan to produce longer term forecasts to give suppliers a longer term view of likely obligations in future quarters Levy setting Cash monitoring Advanced warning https://lowcarboncontracts.uk/

Agenda 1. Introduction 2. Supplier obligation (SO) Main drivers of uncertainty How we deal with uncertainty Process Forecasting The reserve 3. Transparency tool 4. Key dates 5. Longer term outlook https://lowcarboncontracts.uk/

SO: What are the main drivers of uncertainty? SO Levy ( /MWh) = (StrikePrice ( /MWh) MarketReferencePrice /MWh ) Generation (MWh) Total Eligible Demand (MWh) Market reference prices: Baseload (eg biomass) Intermittent (eg wind or solar) both dependent on market prices Generation Wind very uncertain day to day Solar uncertain hour to hour Biomass reasonably certain unless there is an unplanned outage https://lowcarboncontracts.uk/

SO: Dealing with uncertainty Market reference prices Spectron* power prices Industry standard volatility model Wind generation Sampled from historic wind speeds Use NASA MERRA** data set for UK Solar data Sampled from historic sunshine hours Use met office data from across UK All input into Supplier Obligation Forecasting Model (SOFM) Montecarlo*** Simulation Model Typically run with 5000-10000 simulations *Spectron is a leading commodities broker and has a leading position in GB power market ** The MERRA data includes worldwide wind speeds at defined longitude latitude and height and is made available free of charge by NASA *** Montecarlo simulation is a standard industry approach to assessing the impact of uncertainty https://lowcarboncontracts.uk/

Agenda 1. Introduction 2. More about the supplier obligation 3. The Transparency Tool 1. Purpose of the tool 2. View of current tool 3. Intended development 4. Key dates 5. Longer Term Outlook https://lowcarboncontracts.uk/

Transparency Tool Remit 1. We have developed this Transparency Tool, consulting closely with experts from our Working Groups, in order to provide our stakeholders with insight into our assumptions and calculations. Requires access via LCCC Site and supplier logon credentials 2. Purpose is to give visibility of the calculations supporting the Interim Levy Rate and Total Reserve Amount Confidence for suppliers that the calculations are correct Understanding of the generation assumptions in the model Understanding of the uncertainty 3. Includes 15 month forecasts, with base case and sensitivities (see later) https://lowcarboncontracts.uk/

Transparency Tool: current view (demonstration) https://lowcarboncontracts.uk/

Transparency tool shows ILR/TRA and forecasts https://lowcarboncontracts.uk/

Agenda 1. Introduction 2. More about the supplier obligation 3. The transparency tool 4. Key dates 5. Longer Term Outlook https://lowcarboncontracts.uk/

Key Dates for 2016 Date Event By 31 Dec 15 Set levy rate and reserve for April-June 16, refresh forecast for July-Sept 16 and Oct Dec 16 and first forecast for Jan-Mar 17 By 31 Mar 16 Set levy rate and reserve for July-Sept 2016, refresh forecast for July-Sept 16 and Oct Dec 16 and first forecast for Jan-Mar 17 By 30 June 16 Set levy rate and reserve for Oct-Dec 2016, refresh forecast for Jan-Mar 1716 and Apr-June 17 and first forecast for July-Sept 17 By 30 Sept 16 Set levy rate and reserve for Jan-Mar 17, refresh forecast for Apr-June 17 and July Sept 17 and first forecast for Oct-Dec 17 By 31 Dec 16 Set levy rate and reserve for April-June 17, refresh forecast for July-Sept 17 and Oct Dec 17 and first forecast for Jan-Mar 18 https://lowcarboncontracts.uk/

Agenda 1. Introduction 2. More about the Supplier Obligation 3. The Transparency Tool 4. Key dates 5. Longer term outlook Why forecast? Principles of forecasting Way forward https://lowcarboncontracts.uk/

Longer term outlook: principles 1. Mimic the SOFM forecasting process for producing the Interim Levy Rate (ILR) and Total Reserve Amount (TRA) Essentially same approach to uncertain generation Market price uncertainty mimicking the way in which the levy setting run would be produced Forecast point Market price 4 months to quarter Start of quarter Market price kept constant until 4 months before quarter, then uncertainty brought in calculate correct TRA 2. Forecast only for known CFD generators No speculation on contracts arising from future allocation rounds Using public information for generator start dates (TCDs or other information the generator consents to be used for the purpose) 3. Approach to CFD start dates Base case and potentially one or more sensitivities (eg generator commissions late, market price drops ) https://lowcarboncontracts.uk/

Longer term outlook: way forward 1. Forecasting refresh intend to refresh forecasts quarterly in line with setting the rate and reserve for a new quarterly obligation period Look at appropriate base case and sensitivities on a case-by-case basis 2.
