Electrification has become key for the global move toward cleaner energy, even as government policies continue to impact the use of renewable resources and in some cases embrace continued and even increased support for fossil fuels. Governments and industries wanting to reduce their emissions of greenhouse gases look to electrification not only as an environmental […]

Ten years ago, utilities could plan for new 100-megawatt (MW) load requests. That size of energy load fit inside existing forecasts: it could be absorbed, modeled and planned around. Today, load requests have increased to one, two even three gigawatts (GW) at a time. This results in utilities fielding individual load requests that rival full […]

Microgrids are bringing greater energy independence to rural and remote communities. ABB’s microgrids experts outline how today’s smart localized power generation and distribution systems lessen far-flung homes and businesses’ reliance on costly fossil fuels and fragile national grid infrastructures.

On April 24, 1996, the Federal Energy Regulatory Commission (FERC) issued Order 888, requiring all public utilities owning or operating interstate transmission facilities to file open-access

With electricity demand projected to rise 25% by 2030 and 78% by 2050 from 2023 levels, utilities are facing a perfect storm—aging infrastructure, climate-driven disruptions, and escalating expectations for reliability and resilience. Meeting this moment will require more than incremental improvement; it demands entirely new sources of capacity, and a fundamental rethink of how the […]

The Department of Energy (DOE) has closed a $26.54 billion loan package—the largest single loan commitment in the agency’s history—with Southern Co. subsidiaries Georgia Power and Alabama Power to finance more than 16 GW of “firm” generation and more than 1,300 miles of transmission infrastructure and grid enhancement across the Southeast. The transaction, announced Feb. […]

A Texas-headquartered energy company with installations in more than 20 states has brought a utility-scale battery energy storage project online in Maine. Plus Power on February 11 said the group’s 175-MW/350-MWh Cross Town Energy Storage facility is now the largest of its kind in New England.

The challenge of upgrading how power is generated, along with needed improvements in electricity transmission and distribution, is being met in a variety of ways by an array of companies.

Energy provide Constellation said that Calpine LLC, a business unit of Constellation, has signed a new 380-MW agreement with Dallas, Texas-based CyrusOne, a global data center developer and operator, to connect and serve a new data center adjacent to the Freestone Energy Center in Freestone County, Texas.

Global energy company GE Vernova announced the launch of another offering in the group’s GridBeats portfolio, which features software-defined automation solutions designed to modernize electrical grids by improving resilience, efficiency, and flexibility.

Energy-generation permitting in the Mid-Atlantic continues to evolve in 2026 not through wholesale deregulation or uniform acceleration, but through procedural and permitting reform and the potential allocation of generation development authority to public utilities. States are enacting these changes to meet the reality of reliability concerns, transmission constraints, large load-growth, and to address frequent obstruction of energy projects by local government.

A subsidiary of Spanish energy giant Iberdrola said it has energized a major transmission line project in Brazil.

For more than 60 years, polyethylene (PE) and ethylene-propylene rubber (EPR) underground cables have powered communities, industries, and progress. The hope was these cables could last decades before needing to be replaced, but due to water treeing—microscopic moisture-induced formations that degrade insulation and threaten reliability, they’re aging more rapidly than expected. With traditional replacement being costly and labor-intensive, it was time for a new solution.
