Over the last 12 months, wind and solar accounted for 80% of new capacity installed.<\/p>\n\n\n\n\n\n\n\n
Coal fell to less than 2% of the generation mix. This quarter saw the first full day when no electricity was produced from coal, on April 21st. There were 315 hours this quarter with zero coal output, already twice as many as during all of 2016. Coal stations ran at just 4% of full output over the quarter, seeming to have found a new \u2018floor\u2019 of generating 600 MW on average, from 14,000 MW of capacity. There were only eight days in the quarter when coal produced more than biomass, and five days when it produced more than wind or solar.<\/p>\n\n\n\n
Prices eased back to \u00a340\/MWh day-ahead and \u00a341.50\/MWh real-time, after a small rise over winter. Negative prices were seen in 12 hours over 7 days, including four hours overnight on June 7th, and four hours in mid-afternoon on June 24th. At the other extreme, prices spiked to \u00a3388\/MWh day-ahead (over \u00a31,500\/MWh real-time) on May 17th, when wind and solar output dropped by two-thirds from the previous day, margins were tight, and several coal units were started up to fill the gap.<\/p>\n\n\n\n
