SUBSCRIBER NOTE: UK dark, clean dark spread launch

Following a period of consultation, to reflect the role coal-fired generation plays in the UK energy mix, Platts will launch the following daily dark and clean dark spread assessments, effective April 2, 2013: month-ahead, month-ahead + 1, quarter-ahead, quarter-ahead + 1 and season-ahead. The formula for dark spreads will use an energy conversion factor of 7.1 (converting 1 tonne of coal into MWh) and a fuel efficiency factor of 35%. The formula for clean dark spreads will use the same energy conversion and fuel efficiency factors and a carbon intensity factor of 0.96. The assessments will be published in Platts European Power Daily, Coal Trader International, on Platts European Power Alert and in Platts Market Data.
