Concerns About Summer Reliability in Texas and California Persist

Higher-than-average temperatures forecast for much of the U.S. this summer won’t affect reliability in most regions, though concerns remain for Texas and Southern California, according to the Federal Energy Regulatory Commission (FERC). Presenting the “Summer 2018 Energy Market and Reliability Assessment,” on May 17,  FERC staff said that most entities that are part of the […]

Sufficient Blackstart Capability Exists on Grid, Say NERC, FERC

  Despite the recent retirement of “blackstart” units, grid operators have sufficient resources to quickly restore systems in the event of widespread outages, suggests a new report by staff at the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC). The report—“FERC-NERC-Regional Entity Joint Review of Restoration and Recovery Plans”—released May […]

Facing a Supply Crunch, ERCOT to Revamp Reserve Margin Targets

The Electric Reliability Council of Texas (ERCOT) on April 30 updated its summer 2018 planning reserve margin to 11% based on resource updates, but it warned that the regional grid serving most of Texas could still suffer rotating outages under extreme conditions. In its final Seasonal Assessment of Resource Adequacy (SARA) report for the upcoming […]

Upgrading infrastructure. The Nigerian government is working to improve the country’s power infrastructure, with plans for new power plants and upgrades to transmission and distribution systems. Much of the work is being financed by China. More than 40% of Nigerians live without electricity. Courtesy: Nigeria Electricity Hub

Pipeline Project Prompts Plan for Nigeria Power Plants

The Nigerian National Petroleum Corp. (NNPC) in December 2017 announced a plan to build three natural gas-fired power plants in the country, thanks to a $2.8 billion pipeline project that would bring natural gas from the southern part of the African nation to its northern region. The plants, sited in Abuja, Kaduna, and Kano, would […]

Using Artificial Intelligence to Protect the U.S. Power Grid

The North American Electric Reliability Corp. (NERC) standard on physical security—known as Critical Infrastructure Protection-014 (CIP-014)—includes six basic requirements, but perhaps the most

More Utility Workers in Puerto Rico as Power Restoration Continues

U.S. utilities continue to send workers to Puerto Rico to help restore that country’s electricity and rebuild its power infrastructure, a task that continues more than four months after back-to-back hurricanes left nearly all of the island in the dark. The Puerto Rican government this week said 83% of the island’s generation capacity has been […]

Swinging into action. A control system demonstrated in three trials on the western grid last year damped inter-area oscillations on the western grid. The system could allow utilities to push more power through transmission lines. Source: Sandia National Laboratories

Decade-Old Power Grid Problem Solved by Smart Grid Technology 

A control system that smooths out inter-area oscillations—a problem affecting power systems connected by relatively weak tie lines—has been successfully demonstrated by researchers from Sandia National Laboratories and Montana Tech University. The system that uses smart grid technology could allow utilities to push more power through transmission lines, possibly nixing the need for new transmission […]

A Bird’s-Eye View: Drones in the Power Sector

Unmanned aerial systems—drones—have quickly found their place in the power sector. But as the industry moves out of test cases and experiments, and into full implementation of drones, it is facing a whole
