As a result, in many countries these processes forced utilities to reduce maintenance and inspection frequency and accept greater operating risk, albeit through managed risk assessment and mitigation programs. There is both factual and anecdotal evidence that in some instances the risk envelope is being stretched quite significantly compared to previous practice.

Power generation and electromechanical energy conversion

This Technical Brochure has been created by a Working Group from the CIGRE Power generation and electromechanical energy conversion Study Committee which is one of CIGRE's 16 domains of work.
The SC covers all aspects of electromechanical energy conversion equipment, rotating electrical machines for power generation, grid support, and energy conversion within industrial applications. This includes research, development, design, manufacture and testing of power generation and electromechanical energy conversion equipment and their associated auxiliaries, commissioning, operation, condition assessment, maintenance, life extension, refurbishment, upgrades, efficiency improvement, conversion, storage and de-commissioning.
