El Hierro completes a year of full operation

At the end of June the Gorona del Viento (GdV) plant completed its first year of full operation, during which it supplied 34.6% of El Hierro’s electricity demand with renewable electricity at a cost probably exceeding €1.00/kWh while lowering the island’s CO2 emissions by approximately 12,000 tons at a cost of around €1,000/ton. This post summarizes these unexpectedly poor results, discusses the reasons for them and concludes that GdV, which was intended to show the world how fossil fuel generation can readily be replaced with intermittent renewables, can already be classified as a “failed project”.

Solar in Chile

Solar power in 2015 accounted for less than 5% of Chile’s total electricity generation, but because of decreased demand and inadequate grid connections it’s already generating surpluses that have to be curtailed or which result in the power being sold at zero cost . Yet to meet its target of 20% renewable energy from non-hydro sources by 2025 Chile plans to install yet more intermittent solar and wind energy by 2020/21. Continue reading

Decarbonising UK Power Generation – The Nuclear Option

How to decarbonise UK Power generation is a topic of heated debate, with renewables enthusiasts often keen to argue that there are a range of obstacles to the use of nuclear generation to meet more than a small proportion of total demand. Reasons cited are availability of space/sites, grid integration and the challenges of meeting variable demand. So, is an all-nuclear UK grid (with the small sleight of hand of pumped storage hydro in support) potentially viable? Continue reading
