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

El Hierro, January/February 2016 update:

The Gorona del Viento (GdV) plant on the Canary Island of El Hierro is a flagship project designed ultimately to provide the island with 100% renewable electricity. The low-wind conditions that dominated during the last four months of 2015 continued into January 2016, leading to only 22% renewables generation in that month. Much of February, however, was characterized by strong winds, and combined with the 100% renewables tests that were performed this resulted in renewable energy supplying 54% of El Hierro’s grid demand in that month, exceeding the 52% achieved in June/July 2015.

El Hierro – now up to 41 hours of 100% renewables generation

The El Hierro GdV project produced 100% renewables generation between 1 am on February 14 and 17.40 on February 15. But still enough to eclipse the 33 hours of 100% renewables generation achieved at King Island, Tasmania, last November. So congratulations to the GdV project staff. Continue reading

Estimating Storage Requirements At High Levels of Wind Penetration

In recent posts and comments there have been a number of back-of-the-envelope estimates – including some from yours truly – of how much pumped hydro storage would be needed to bridge some of the low-wind periods that have been registered in the UK. Here I take a closer look at the question of how much wind power storage would be needed at the high-penetration grid scale. Continue reading

The Coire Glas pumped storage scheme – a massive but puny beast

Coire Glas, therefore, is simply window dressing in efforts to “Green” UK power supply with pylons, turbines and dams. Continue reading
