Renewables and gas infrastructure

While there has been extensive discussion and analysis of the requirements for integration of renewableelectricity generators with the electric grid, there has been much less focus on the interactions with thenatural gas grid, which, nevertheless, could be significant. There is widespread agreement that gas-based generation will be an important component of renewable integration but there has been little detailed analysis to date of the potential interactions between the electric and natural gas systems.

Improving Generator Reliability

One session of the 7EA User Conference dealt with generator reliability. The factors affecting reliability include the unique characteristics of each machine, its age/condition, history, operational and operator actions (cycling, loading, trips, restarts, synchronous condensing, motoring and so on), environment, external events and acts of god. The smart policy is to form a maintenance plan and carry it out systematically.
