Today’s construction boom in the combined cycle/cogeneration sector is great news for suppliers of gas turbines (GTs), heat recovery steam generators (HRSGs), and engineer-procure-construct (EPC) services. But before this boom advances from artist’s sketches (Figure 1) to first fires, the designers of all those next-generation combined cycles should pause to reflect on the lessons learned […]

In May, GE’s Power Services and Ansaldo Energia separately completed initial validation of two gas turbines designed for high efficiency and flexibility: the 9EMax and the GT36. GE also announced first fire

Southern California Edison (SCE) put online the world’s first battery–gas turbine hybrid system on March 30 in Norwalk, Calif., pioneering a new direction in the way power could be generated and stored

Power plants are complex systems with countless moving parts, and in turn, countless opportunities for things to go wrong. With the advent of 3-D printing technology, repairing or replacing those moving parts

UK Gives First Consent for Hinkley Point C EPRs. The UK’s Office for Nuclear Regulation (ONR) on March 27 gave its approval to allow a consortium to begin placing structural concrete for a series of

An inlet air cooling (IAC) system offers one of the most cost-effective ways to improve gas turbine (GT) performance—especially during the peak hours of hot summer months. After all, GT output depends on

Varnish buildup in oil systems and components can degrade performance and cause erratic valve operation. Some experts have conducted research and formulated new lubricants that could help solve those problems. One such oil proved highly successful during a five-year run at a gas turbine power plant. By eliminating the need for oil changes and valve […]

Russia Marks Milestone with Commercial Operation of Third-Generation Reactor. After nearly a decade of construction, the first advanced third-generation VVER-1200 nuclear reactor began commercial operation on

Today, some F-class operators continue to opt for rotor-out major inspections, which are cumbersome and inefficient. They involve complex lifts and moves of the rotor, as well as the need for substantial space

Cycling a combined cycle plant places additional stresses on all equipment, but the impacts extend beyond the gas turbine and heat recovery steam generator. Plant owners and managers are beginning to see
