On Monday, October 2, wind turbines generated enough power to meet all Scotland’s electricity needs and then some. WWF Scotland confirmed this was a record for 2017.
Analysis by WWF Scotland of data provided by WeatherEnergy found that on that date wind turbines provided 86,467 MWH of electricity to the National Grid. Scotland’s total electricity use for Monday was 41,866 MWh. Translated this means wind power generated the equivalent of 206% of Scotland’s entire electricity needs on the day.
“Monday proved to be a great day for renewable electricity output, with wind turbines alone providing enough to power 7 million homes and way more than Scotland’s total electricity needs,” stated WWF Scotland’s Director Sam Gardner.
September was also an impressive month for wind power, providing enough electricity for 126% of Scottish households over the 30 day period, or around two-thirds of total Scottish demand. Wind turbines in Scotland alone provided 1,108,862 MWh of electricity to the National Grid, enough to supply, on average, the electrical needs of 3 million Scottish households.
Scotland’s total electricity consumption (i.e. including homes, business and industry) for September was 1,768,505 MWh. Wind power therefore generated the equivalent of 63% of Scotland’s entire electricity needs for the month.
Speaking about all renewable, Dr. Garner said, “Scotland’s renewable sector is thriving but to make sure that we have the most efficient, cheapest system possible, we need more focus on electricity storage, reducing demand and strengthening networks
“The forthcoming Climate Change Bill and Warm Homes Bill provide vital opportunities to enshrine ambitious commitments in law and to lead global growth industries,” he conluded.
The 7 rows (A to G) of this \"Grid Watch Demand Focus Table\" suggest different system configurations which could supply the same \"86,467MWh\" every day of the year. https://uploads.disquscdn.com/images/7f4227e99c6fd11842ee6d8e4591e6b392ec991bb4f8bc2081c76422ea29fcb1.jpg Not that we have that in Scotland yet. For a 100% renewable energy system, the \"Back-up power\" would be biomass, biogas or other (most ly hydrogen from electrolysis of water using surplus wind power) gas-to-power. For now, most of the back-up power to wind is fossil fuel natural gas burning power stations and most of that capacity is in England, embarrassingly. Scotland only has about 16,000 MWh of energy storage because we couldn\'t get funding for our pumped-storage hydro plans.

Adopting the recommendation derived from scientific computer modelling that the energy storage capacity be about 5 hours times the wind power capacity, the tables offer rows of previously successful modelled system configurations - row A, a configuration with no back-up power and rows B to G offering alternative ratios of wind power to back-up power. Columns consist of adjustable power and energy values in proportion to fixed multiplier factors.
