Technical, legal, and regulatory articles on water-related topics for power plants: cooling, wastewater, intake, chemistry, purge water, and once-through systems
Plans to build a pumped-storage hydroelectric plant in the world’s driest region won the approval of environmental regulators in Chile this December. The unique 300-MW project proposed by Valhalla Energia…
Nondestructive technologies make the inspection of a plant’s least accessible components relatively easy and deliver results that minimize unexpected failure—and expense. When we undertook an initiative at Granite Ridge Energy…
Congressional efforts to block the Environmental Protection Agency's (EPA's) contentious rule asserting federal authority over small bodies of water were derailed on Jan. 21. Senate Republicans voted 52–40, failing to…
From issuance of the final Clean Power Plan to mammoth mergers, 2015 will be remembered as a tumultuous year. Twelve months ago, as folks were emerging from an eventful 2014,…
Owner/operator: K-water The world’s largest power-producing tidal barrage revitalized an unsuccessful manmade reservoir that was once known as “The Lake of Death.” From space, the 12.7-kilometer (km) Sihwa Lake tidal…
The first effluent limitation guidelines update since 1982 is game-changing for many U.S. power plants. This unfiltered look at the rule and its nuances will help you understand how each…
Zero-liquid discharge (ZLD) water treatment is already required in some parts of the world, and the experience gained in those areas with new technologies may help power generators in other…
The Environmental Protection Agency (EPA) has finalized revisions to technology-based effluent limitations guidelines and standards, setting the first federal limits on the levels of toxic metals in wastewater discharges from…
In cooling water chemistry for power plants, it is not enough to control one or two of the major chemistry issues. Successful treatment requires simultaneous control of corrosion, scale, and…
