Record wind energy output last month kept electricity prices down

wind-nuclear-Wind energy’s biggest month, and how it keeps prices down REneweconomy,  EBy Giles Parkinson on 8 June 2016 Wind energy in Australia has enjoyed its biggest every month in May, producing nearly a quarter more electricity than its previous record month, and overtaking hydro to provide 8.5 per cent of electricity demand in the country’s main grid.

The record output came, coincidentally, in the same month that the last coal fired power station in South Australia was closed (May 9). And a new analysis from energy consultants Pitt & Sherry points to how wind generation is keeping a lid on wholesale electricity prices.

The Pitt & Sherry analysis notes that four states recorded record monthly totals in May – South Australia (where wind met 49 per cent of demand), Victoria, New South Wales and Tasmania. (There is only one very small wind farm in Queensland and Western Australia operates on a separate grid).

The 3.9GW of wind generation in the month of May operated at a capacity factor of 49 per cent, according to Pitt & Sherry, meaning that it produced 22 per cent more than it did in its previous record month (July, 2015). (See this story for more details, and how most wind farms in NSW operated at a higher capacity factor than some of the biggest coal plants).

South Australia has the biggest share of wind farms, with 1.5GW, and this accounted for 49 per cent of its electricity demend in the month. On some occasions, wind energy provided more than 100 per cent of electricity demand in the state.…….
