Challenges of Intermittency in NW Europe

4 July 2011

This talk was given by Stephen Woodhouse, Director with Pöyry Management Consulting in Oxford, on July 4, 2012 at the IEA Headquarters in Paris, France.

Stephen Woodhouse will present Pöyry's work on the market consequences of 'intermittency', assessing the implications of high penetration of autonomous generation across 14 markets of Northern Europe. This was a multi-client study covering the areas of North Sea wind, German solar and Nordic and Alpine hydro generation.   The modelling combined detailed hourly wind and solar patterns for eight years, stochastic dynamic programming to calculate hydro reservoir value, and linear programming to optimise total system costs. Pöyry addressed the related questions of market volatility, generation capture prices (including 'wind cannibalisation'), the investment paradigm for conventional and renewable generation and the cost to consumers.  Cases tested included a capacity payment, a 'Supergrid', demand management, alternative routes to decarbonisation and a separation of Germany into price zones.

Stephen Woodhouse is a Director with Pöyry Management Consulting in Oxford, joining the company in 1999.  He heads Pöyry’s Market Design group which deals with all aspects of energy market policy regulation and design, for private and public-sector clients.  

Stephen is an expert in market reform, from high-level policy design to commercial implications and strategic response through to the implementation of systems and processes for market participants.   He specialises in the economics of transmission and interconnection; market regulatory policy across Europe and the UK, Irish and wider European electricity markets. Stephen managed the project to draft the Trading and Settlement Code for the Irish Single Electricity Market and was responsible for Pöyry’s multi-client projects addressing intermittency in Northern Europe. He is working with organisations across Europe on the implementation of the Target Model, and is leading Pöyry's work on the definition of future energy market design.  Prior to joining Pöyry, he was an Economic Modeller for Ofgem. Stephen has an MA in economics from the University of Cambridge.
