However the construction of the 1000 MW plants in the premise began in the year 2007.

The 885 MW plant was expected to cost £400 million and to start generating in early 2009, but problems with internal pipework pushed this back.

In comparison, a 1,000 MW nuclear plant will generate about 30 short tons of high-level radioactive solid packed waste per year.

The 192 MW plant started full-scale operations in 1990.

With the building of the two 600 MW plants a large jump forward occurred.

Despite opposition, the agency went ahead in December 1982 with its $23 million plan to install a 10 MW generating plant.

A later study and final design was completed in 2005 by Studio Pietrangeli for the current 460 MW plant.

In addition, a new 500 MW plant is under construction, which is likely to be commissioned in 2012-13.

In 2009, the Arizona state government announced a 200 MW plant for 1 billion US dollars.

The 850 MW plant uses air cooling technology to reduce water consumption.
