Scotland’s Wind Dream May Turn Into A Nightmare
I last looked into the details and consequences of Scottish energy policy in the pre-referendum post Scotch on the ROCs. The expansion of Scottish renewables is progressing at breakneck speed and the purpose of this post is to update on where we are and where we are heading whether anyone likes it or not (Figure 1). Objections to wind power normally come from rural dwelling country folks whose lives are impacted by the construction of wind turbine power stations around them. My objections tend to be rooted more in the raison d’être for renewables (CO2 reduction), their cost, grid reliability and gross environmental impact. One issue I want to draw attention to is the vast electricity surplus that Scotland will produce on windy days in the years ahead. That surplus has to be paid for. Where will it go and how will it be used?
Figure 1 The rapidly changing face of electricity generation in Scotland. Wind power seems destined to grow from virtually nothing in 2010 to 15.8 GW come 2020. Maximum power demand in Scotland is 6 GW (red line).
This post was prompted by a couple of emails in the wake of my recent post onWWF Masters of Spin that brought my attention to two short reports prepared by Professor (emeritus) Jack Ponton that describe how operational and consented wind farms will already take Scotland beyond its 2020 target. The small pdfs can be downloaded here and here and the two key charts are reproduced below.
