Impact of intermittency on GB and Irish markets

This ground-breaking multi-client study was the first to examine in detail the implications of the expected rapid growth in electricity generation from variable renewable sources in GB and Ireland.

The ultimate aim of the study was to answer the question 'How will the impact of intermittent generation affect the wholesale energy markets in GB and Ireland?'.

The study was joined by four major utilities (including three of the 'big six'), two grid companies, two regulatory bodies and two major wind developers.  It covered entirely new ground, and has given the first comprehensive analysis of the impact of wind on market players, along with commercial and strategic insights.

The study answered questions in the following areas:

  • market prices;
  • plant operation and new thermal generation;
  • wind revenue;
  • reserve and response;
  • interconnection and transmission; and
  • market arrangements.

-
The study was built on a dedicated modelling platform ('Zephyr'), which combined actual historical weather data, plant availability and demand to give a high degree of resolution on the impact of wind on the GB and Irish markets. The highly-quoted public report on the study was responsible for changing the debate on the future of the UK electricity market.
