Zero-Trust Gateways: A New Strategy for Protecting Critical Infrastructure
In early May 2021, a Russian cyber-criminal group hit Colonial Pipeline, the largest U.S. oil and natural gas pipeline system, with a devastating ransomware attack. The exploit maliciously encrypts computer files, making them inaccessible unless the victim pays a ransom. To contain the threat, Colonial was forced to temporarily shut down portions of its operations […]

Power Industry Automated Scraper Strainers Filter Full Spectrum of Debris Sizes
Unlike backwash systems, scraper strainers reliably resist clogging and fouling when faced with micron-sized particles, oversized solids, and high solids concentration. The power generation industry often prefilters raw water from rivers, lakes, gulfs, and coastlines to remove organic, aquatic, and other solids for use as cooling water. Typically, with once-through systems, water circulates through pipes, […]

New Gas-Fired Units Would Replace Coal at Indiana Plant
CenterPoint Energy could begin construction of two new natural gas-fired units to serve electricity customers in Indiana as soon as next year, if state regulators approve the utility’s plan that includes the closure of two units of a coal-fired power plant at a site along the Ohio River. CenterPoint’s $323-million proposal to the Indiana Utility […]

Xcel Scrapping Plan to Build New 800-MW Gas-Fired Plant
Xcel Energy is pivoting from its plan to build a new 800-MW natural gas-fired power plant at the site of its Sherco coal-fired facility in Becker, Minnesota. Instead, Xcel plans to build two smaller gas-fired “peaker” plants, one in Minnesota and one in North Dakota, as part of a new initiative for the utility’s power […]

Consumers Energy to Quit Coal by 2025, Speeding Closure of Five Units
Michigan’s largest energy provider Consumers Energy will stop using coal as a fuel source for power generation within the next four years—15 years earlier than previously planned. In an updated integrated resource plan (IRP) filed with the Michigan Public Service Commission (MPSC) on June 23, the CMS Energy subsidiary said the effort would lead Michigan’s […]

A Game-Changing Vision for Geothermal Energy
According to a report released in 2019 by the U.S. Department of Energy, geothermal electricity generation could increase more than 26-fold by 2050—reaching 60 GW of installed capacity. That may seem like a pipe dream to some power observers, but if new well-drilling techniques allow enhanced geothermal systems to become economical, the reality could be […]

GE Hitachi: Nuclear Costs, Innovation Must Be a Pivotal Focus for Carbon-Free Future
Nuclear energy’s future as a critical pillar in a decarbonized world will depend on its adaptability to rapid change, but the sector must focus on costs, certainty of outcome, reliability, and experience to cement its role beyond the transition, GE Hitachi Nuclear Energy (GEH) President and CEO Jay Wileman told POWER in an exclusive interview.

Carbon Capture
CCUS: Big Opportunity and Hard Questions
For the world to avoid a climate catastrophe, carbon capture is likely a necessity, not an option. To meet the Paris Agreement’s objectives—keep warming below 2C and preferably near 1.5C—net zero carbon emissions must be achieved circa 2050, and some carbon dioxide will have to be extracted from the atmosphere. Deployment of carbon capture, utilization, […]

How to Prevent Bacterial Growth in Dry and Wet Cooling Systems
Accumulation of debris in water systems can cause dangerous bacterial growth and performance loss—this is how to reduce the risk. In cooling systems, airborne debris, such as dust and leaves, or water depositions, such as scales or inorganic/organic particles, can accumulate on the surfaces of cooling tower fills or the fin coils of air blast […]

Despite South Carolina IRP Rejection, Duke Energy Seeks 80-Year Operation for Oconee Nuclear Units
Duke Energy has kicked off an effort to renew the operating licenses of all its 11 nuclear reactors for 20 more years, starting with Oconee Nuclear Station, its largest nuclear plant. The utility on June 21 filed an application with the U.S. Nuclear Regulatory Commission (NRC) for a subsequent license renewal (SLR) for the three-unit 2.5-GW […]
