Environment
Data for 2009

 Last year Deeside generated 2924 GWh.
 Enough to meet the needs of about half a million people.

In order to generate this electricity Deeside burnt 441,395 tonnes of natural gas.

This gas is delivered at a pressure of 26 bar.

Emissions to air:
CO – 571 tonnes, CO2 – 1,158,095 tonnes,
NOx – 1240 tonnes, SO2 – 13.2 tonnes

We abstracted 2,554,537 m3 of water from the River Dee.This is to condense the steam from the steam turbine.Some of this water evaporates in the towers. We returned almost 1,525,695 m3 a few degrees warmer but within defined limits.

We used 133,982 m3 of town mains water last year for generating steam to produce electricity from the steam turbine.
