Typical Regulatory Objectives
• the lights stay on • the gas continues to flow • prices for energy are fair and reasonable • Complying with environment policy and laws • Best practice regulatory processes

The Wholesale Market
• Interconnectors historically underused, markets segmented
• Uneconomic cross border flows undermine EU energy policy goals of sustainability, competitiveness and security of supply
• EU has addressed this by forging an internal market in electricity to form part of single European market in goods and services
European Context
Creating the Single Market
• 1st and 2nd electricity liberalisation packages (1996 and 2003):
– Some success but price correlation between regional markets remained poor and cross border capacity was inadequate or inefficiently used
• 3rd electricity liberalisation package (2009): – Establishment of ACER and ENSTO-E – harmonisation of market rules - market coupling – increase in physical cross border investment
• Target Model – end 2014 – SEM derogation to end 2016

• Gross Pool markets are centrally dispatched with TSOs deciding centrally on generator running order
• Bilateral markets like those in Britain and continental Europe are self dispatch, where TSOs only balance the system close to real time
Different Market Designs
SEM British Market
European Target Model
Long-term allocation
Day-ahead implicit auctions
Intraday continuous trading
Cross-border balancing
Zone delineation Capacity calculation
Common cross-border arrangements
Diverse national arrangements
The interaction between the two should encourage harmonisation
How it works…
• Rules for calculating and allocating cross border capacity – Auction Rules – Allocation Platforms
• Cross Border Risk Hedging and Firmness – Physical Transmission Rights (PTRs) with UIOSI – Financial Transmission Rights (FTRs) – Other hedging tools if sufficient liquidity exists
Forward Capacity Allocation
• Centrepiece of the Target Model • Links separate day-ahead spot markets using cross-border (XB) transmission
capacity • It is an “implicit auction” – meaning cross border capacity allocation is integrated
with the energy market (‘explicit auctions’ sell capacity separately) • Common prices between spot markets when there is sufficient capacity
Day Ahead Market Coupling
Market Coupling (2)
If there are XB capacity constraints, these will limit the flows between the coupled markets and a price difference will persist

Future Issues – Capacity Mechanism • Target Model is being finalised and is due to be implemented by 2014 • But, in parallel several Member States have or are considering CRMs
– Generation Adequacy– e.g. German nuclear closures and LCPD impacts – Missing money problem – Impact of RES on energy only markets
Does Clean Energy need Support?
• Limits of Energy Only market (marginal cost) • High Capex, Low Opex • Reducing cost of capital • Regulatory/Policy Certainty
Elements of Market Dysfunction
• Cheap Coal from US
• Dropping gas demand
• Good Utility/Bad Utility – security of supply?
• Nuclear Support
• Cost competitiveness for large industry
The Transmission System
• Much wind in west, demand in east
• Rolling out the grid is critical to meeting 2020 renewable target
• EirGrid has major Grid 25 plan
• Over €1 billion in grid investment allowed by CER from 2011 to ‘15
• Planning and land access are a major challenge
Grid Roll-out
DS3 Project Delivering a Secure, Sustainable, Electricity System (“DS3”) – integrating wind while maintaining secure operation of system • 75% instantaneous wind
penetration; • Greater flexibility from
conventional plant (existing & new);
• RoCoF settings • Keep curtailment to
“bankable” levels i.e. 5% • Better wind forecasting,
real time data and controllability;
• Demand Side Management;
• Cost & Benefit to consumers
System Non-Synchronous Penetration (SNSP)
50% SNSP 75% SNSP
The Distribution System
Changes to DSO
• New technologies such as embedded (e.g. micro) generation and electric vehicles
• Smart grids • Smart metering • Demand Side participation • Ancillary service provision and flexibility
DSOs Issues for Regulators
• Distribution tariffs • Promoting innovation • The scope and extent of DSOs functions • Price controls and incentives • Data handling and protection • Future unbundling/separation requirements
The Retail Market
• Green Tariffs • Changing Consumption Behaviour • Smart Meters – Static or Dynamic ToU Tariffs? • Microgeneration Issues • Consumer Confusion & impact on competition • EV integration
Conclusions
• Regulatory Change Needed to Delivery Green Targets: – Wholesale market evolution – Public Friendly Transmission Investment – New Role for DSO – New Engagement with Consumers
