A Warning From The United Kingdom: Renewable Energy May Not Suffice

Kategori : ELECTRICITY ENERGY NEWS, ENERGY AGENDA NEWS, SOLAR ENERGY NEWS, WIND ENERGY & RES NEWS - Tarih : 17 November 2020


An interesting situation has arisen in the United Kingdom, which should draw the attention of all those focused on the “energy transition.” It speaks to the underlying unreliability of renewable energy and, in particular, the current state of green technology. We can learn from Britain’s current struggles that unless or until we drastically improve our alternative energy and electricity storage technology, we are not yet able to engage in a meaning transition.

On November 3rd, National Grid, which operates the electrical system in the United Kingdom, issued an “electricity margin notice,” for the afternoon of November 4. What this essentially meant is that the electricity operator was concerned that electricity supplies could become tight, especially at peak hours. Blackouts were not imminent, but the risk was there.

National Grid was forecasting a shortfall of 740 MW (1.5%) in the extra power plant capacity it needs to have available at all times to meet demand or pick of slack in the event a power plant breaks down. It is important to note that this happened at the beginning of November, not in the heat of summer when air conditioning can strain grids or an abnormally long cold snap in the winter. No, this was not caused by overburdening the grid but by overreliance on unreliable alternative energies.

The reason for this warning was that a mass of cold, calm air moved over the U.K. The cold prompted electricity use while the lack of wind cut the available power generation from onshore and offshore wind farms. Britain’s wind farms are intended to produce, on average, 16.9 GW of energy but were expected to only generate only 2.5 GW of energy at times on Wednesday. Of that 2.5 GW, “system constraints” prevent the use of 1.2 GW.

At the same time, several natural gas and nuclear powerplants in the U.K. are currently undergoing maintenance. As a result, they are offline. The situation became so dire this week, that old coal-fired power plants that are typically out of service were fired up to provide support.
