Environmental requirements for power system projects

Utilities, as the owners of power system assets, are responsible for asset´s impacts on the environment during the asset´s whole service life from the purchasing to the decommissioning. Measures for preventing or reducing negative environmental impacts have to be applied when installing new assets, repairing and maintaining existing assets, decommissioning old or damaged assets and improving the existing assets. Those measures may deal with new or old equipment technologies, damaged switchgear, SF6 gas handling, severe oil leaks, damaged transformers, diesel generators with underground tank, damaged high voltage cables, etc. This paper considers the asset management impacts on the environment, proposes measures for their prevention or reduction, and suggests a systematic approach in managing the impacts.
