Secure and Promote* (Season +1, +2, +3, +4) baseload contracts generally rose by £0.10/MWh across the week. However, the Winter-17 contract saw the largest gains, increasing by £0.95/MWh during the working week to above £49/MWh; levels not seen since February. Driving this rise was the French market and concerns about possible nuclear outages over the coming winter. The French nuclear safety authority (ASN) decided that further reviews and tests were required, due to potential issues with the steel manufacturing process used in some reactors. Last winter (Winter-16), prices became very volatile due to French nuclear outages, as the UK-France interconnector frequently operated on export to France in response to higher prices. This caused prices to rise in the UK.
The weekly average day-ahead price was £44.70. Prices for day-ahead baseload power reached a maximum value of £47/MWh on Tuesday 15th. The lowest price, on Saturday 19th, was due to a glut of wind, with over 8GW output sustained all day.
Cashout prices over the last week achieved a mean average of £38.22/MWh, with a minimum price of £3.50/MWh realised for period 8 on Friday 18th August. The most expensive period occurred during half-hour 43 (21:00-21:30) on Tuesday 15th August, at a price of £130.00/MWh, where pumped hydro storage at Dinorwig was utilised.
Renewables and other
Wind output was fairly strong during the week, with an average of 6.2GW output (an increase of 2GW over the previous week) and a peak on Saturday afternoon of 10.5MW. Solar generation reached a high of 7.08GW on Tuesday 15th August. Higher prices on Sunday 20th were supported by low wind generation, where output fell to under 1.4GW.
