Here at Cornwall Protect we aim to help local campaigners to stop Cornwall being ruined by inconsiderate developers.

Here are some of the things that are currently going on at a local level…

Local issues driving MPs to do something about Wind Turbines

101 MPs wrote:

“In these financially straitened times, we think it is unwise to make consumers pay, through taxpayer subsidy, for inefficient and intermittent energy production that typifies onshore wind turbines,”

But the Government said:

“Wind farms were a “cost-effective and valuable part of the UK’s diverse energy mix”. The weatherman occasionally says: “During the course of the afternoon you can expect the wind to gradually pick up and some coastal areas may see gusts of over 40 miles an hour whilst inland the wind won’t quite reach these speeds. Overnight we expect the wind to gradually drop and veer south west during the course of the morning”.

National Grid says:

Because of the uncertain and intermittent nature of the supply of electricity generated by wind turbines we require to maintain a “Short Term Operating Reserve” of fossil fuelled and pumped storage generated electricity. This contingency is necessary because we cannot be certain by how much, or precisely when, wind turbines will over-supply, then under-supply, the firm, constant, balance we have to maintain between the consumer’s demand and the supply from the power stations.

In 2012 we anticipate the cost of this contingency to be £18 million / year and if the Government’s 2020 target for wind power is realised, we anticipate it will rise to £299 million / year. nationalgrid.com/uk/Electricity/Operating+in+2020/2020+Consultation.htm

Wind turbine developers have admitted:

That although the wind turbines stand ready to generate 365 days/year the annual wind speed across the UK means that they can only generate electricity for around 100 days or around 3 days out of every 10. A utilisation efficiency of just 27%. (A base load fossil fuelled power station utilisation efficiency is around 95%)

The consumer pays:

The cost of electricity generated and transmitted from firm generation.

A subsidy to the wind turbine operator for wind energy actually generated.

Compensation if it is too windy to generate electricity.

Compensation to electricity generating companies who vary their output, from that contracted, to allow wind turbines to supply to the grid system.

The cost of the Short Term Operating Reserve generation whether it operates or not.

The environmentalists believe:

That the contribution of wind energy displaces fossil fuelled energy and so eliminates fossil fuelled CO2 emissions.

But the inconvenient truth is:

Because the wind speed is constantly variable it is extremely difficult to predict precisely where and when it will power a wind turbine in any one location. Currently National Grid are trialling an upgraded wind forecasting model but the error remains at around 4 hours which is unacceptable in the minute by minute timeframe required to balance the grid system. Since it takes over 2 to 4 hours to “turn around” a shut down fossil fuelled power station, they do not shut down but simply reduced their output ready to increase it to cover the loss of wind generation as and when the wind dies.
