PACESETTER PLANT: Quantum Energía uses Altamira V outage to reset plant reliability

Quantum Energía emerged as a major player in Mexico’s power sector after Mexico Infrastructure Partners along with Federal Government and Mexico’s pension funds acquired Iberdrola’s 13-plant portfolio in 2024. The company now manages about 8.5 GW of generation, nearly all modern combined-cycle capacity. At Altamira V, a 2025 major outage on Block 2 shows how […]

Maximizing the lifespan of CO catalyst: What operators should check before ordering replacement

For many gas-turbine users, CO-catalyst trouble shows up first as a compliance headache: stack CO starts climbing at low load, differential pressure changes, and the plant is forced to decide whether it is looking at a cleaning issue, a system issue, or end-of-life catalyst. That decision now carries more economic weight than it did a

HV ELECTRICAL: Closing the inspection gap on switchyard high-voltage assets

Tip: Implement a structured visual inspection program for switchyard high-voltage equipment between scheduled maintenance intervals, supported by periodic thermal and acoustic diagnostics, to catch early indicators before they become forced outages. Bryan Miller of RATTLIR LLC recently called CCJ editorial offices to flag something he keeps seeing at gas turbine sites: a significant gap between

Hanwha Power and the new value of the installed fleet

The recent rebranding of Power Systems Manufacturing LLC (PSM) to Hanwha Power is not a cosmetic move. It is a signal that the gas-turbine aftermarket has become strategic again, and an aggressive growth plan paired with innovative engineering is needed to keep up with unprecedented demand. At January’s PSM Asset Managers Conference, a few months

GEV validates clutchless synchronous condensing on 7F.05

GE Vernova (GEV) has installed and validated a clutchless synchronous condenser solution for its 7F.05 gas turbine, enabling transition between power generation and synchronous condensing modes in minutes. This solution expands asset flexibility and grid support capability and may be applicable to other heavy-duty fleets, including E-, F-, and H-class units, following successful validation. As

Taking the noise out of turbine monitoring

High-temperature pressure sensors and accelerometers rarely get much attention when they are doing their jobs. But when a combustion dynamics channel goes noisy, a cable loosens, or a monitoring system starts throwing spikes, the consequences can move quickly from nuisance to risk. That was the practical takeaway from Dave Martin, business development manager at PCB

Easy as 1,2,3: Choose inlet filters based on GT-specific standards

ISO has published the first turbomachinery-specific standards for air intake filters. ISO 29461-1, ISO 29461-2 and ISO 29461-3 establish uniform test methods for efficiency and dust holding capacity, performance in fog and mist, and mechanical integrity at high pressure. While this is not breaking news, the combination of the three standards is a powerful decision-making
