Duke Energy has signed a sweeping partnership with GE Vernova for the supply of advanced gas turbines and associated equipment—potentially securing up to 11 of GE Vernova’s flagship 7HA units to advance specific projects in line with the utility’s integrated resource plans (IRPs). Duke Energy on April 24 said the “arrangement” would help the company […]

As a supplement to POWER’s in-depth April 2025 feature, Gas Power’s Boom Sparks a Turbine Supply Crunch, we’re publishing the full interview with Mitsubishi Power’s Vice President of Business Development for Emerging Technologies, Peter Sawicki. Conducted in March, this Q&A dives deeper into the supply realities underpinning the story: long lead times for gas turbines, […]

An India-based company said it has started commercial operation of a 1,200-MW natural gas-fired power plant in Malaysia, part of a buildout of power generation capacity as that country’s population grows and its economy expands.

Doosan Škoda Power has successfully completed the Rayong project in Thailand (Figure 1). The company delivered a 20-MW steam turbine, including a generator, condenser, and other accessories, to the newly built combined cycle power plant in Rayong Province, near the famous tourist resort of Pattaya. This project is a significant milestone as it is the […]

Many combined cycle power plants (CCPP) and cogeneration or combined heat and power (CHP) plants utilize supplemental firing systems, or duct burners, inside the heat recovery steam generator (HRSG) boilers

Simple cycle gas turbines provide efficiency levels of around 35% to 40%. Combined cycle units boost efficiency to 60% and beyond. But another option is emerging that combines the attributes of simple and combined cycle designs. This hybrid configuration uses a single power turbine expander and recycles exhaust heat back to the combustor to combine […]

Back in the early 2000s, some controversy emerged about the practice of spraying large amounts of fog directly into the compressor. Some claimed that this led to blade erosion, pitting, and scaling. So, is it safe to use wet compression on gas turbines by pumping water droplets into the compressor inlet? The answer is yes—provided […]

In 2018, Cooperative Energy, a generation and transmission co-op headquartered in Hattiesburg, Mississippi, had an issue to deal with. Several years earlier, it had joined the Midcontinent Independent System Operator (MISO), giving the power provider access to a competitive market. However, Cooperative Energy’s R.D. Morrow Sr. Generating Station, a 400-MW two-unit coal-fired facility that had […]

Entergy Texas filed an application with the Public Utility Commission of Texas (PUCT) for approval to build two natural gas power plants—one in Jefferson County and the other in Liberty County. “The Legend and Lone Star Power Stations will address the critical need for increased power generation capacity, support increased economic activity throughout the region, […]

Mitsubishi Power, a division of Mitsubishi Heavy Industries (MHI), announced the company has received an order for gas turbine combined cycle (GTCC) power generation system equipment for Lamma Power Station’s Unit 13. The unit will be built in Hong Kong by The Hongkong Electric Co., Ltd., known as HK Electric. The new turbine has an […]
