1 RE-POWERING MARKETS Market design and regulatin during the transitin t lw-carbn pwer systems Manuel Baritaud Bruegel Brussels, 24 February 2016

2 Pwer markets must evlve t facilitate a lw-carbn transitin Cmpetitive electricity markets are being challenged by the need t decarbnise A pwer market transfrmatin is already underway Demand is stagnating in OECD Eurpe Renewables met 62% f grwth in capacity in OECD Eurpe since 2000 New technlgies prgressing (smart grids, demand respnse, strage) Electricity security is becming mre critical The massive investments required call fr an imprved market framewrk

3 Key dimensins f market framewrk fr decarbnisatin Objective Plicy Type f regulatin Cmpetitive markets Lw-carbn investments Carbn pricing Additinal plicy: Supprt schemes Carbn regulatin Lw-C lng-term supprt Carbn price (trading scheme) Lng-term cntracts Auctins set supprt level Integratin in markets Operatinal efficiency / Reliability and adequacy Netwrk efficiency Shrt-term energy markets Additinal plicy: Capacity markets Regulatin Market rules Scarcity pricing Reliability standards Reginal planning Netwrk cst allcatin Energy prices with a high gegraphical reslutin Energy prices with a high tempral reslutin Dynamic pricing ffers Capacity requirements Capacity prices Demand respnse Demand respnse prduct definitin participatin Cngestin revenues Transmissin auctins Cnsumptin Retail Netwrk tariff structure Retail cmpetitive prices pricing Taxatin and levies Distributed resurces

Their design is key fr decarbnisatin while ensuring electricity security.

Their design is key fr decarbnisatin while ensuring electricity security.

8 When and where t perate and invest? Markets prices with a high gegraphical and tempral reslutin can prvide incentives fr efficient and secure crdinatin f mre cmplex pwer resurces

9 Capacity mechanisms: are they needed? Simplified decisin tree: energy-nly market versus capacity mechanism Getting scarcity prices right during capacity shrtage is a pre-requisite but capacity mechanisms are increasingly used t create a safety net during the transitin.

10 Netwrk average price (AUD per kwh) Netwrk regulatin Future rganisatin f the pwer sectr Netwrk tariff develpment in Australia /8 2008/9 2009/ / / / / /15 SA Pwer Netwrks (SA) Ausgrid (NSW) Endeavur Energy (NSW) Essential Energy (NSW) CitiPwer (VIC) Jemena (VIC) Pwercr (VIC) SP-Ausnet (VIC) United Energy (VIC) Decarbnisatin invlves a mdernised regulatry framewrk t accmmdate the deplyment f renewables and distributin distributed energy resurces

12 Cnclusin: Re-pwering markets Decarbnisatin f the pwer sectr is frcing a rethinking f electricity market design Incremental changes re-pwering - can facilitate the transitin: Shrt-term markets with detailed and transparent infrmatin n when and where t perate and invest Cnsistent framewrk fr lw carbn supprt, CO2 pricing and markets Electricity security requires reliability standards and pricing scarcity right, with capacity mechanisms prviding an additinal safety net A cmprehensive market framewrk balances rules set by regulatrs and cmpetitive markets Many recmmendatins are relevant utside Eurpe, including IEA partner cuntries
