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

It's part of the company's effort to show that renewable energy is viable option for Puerto Rico today and in the future. Courtesy: Louis Berger

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 […]

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

Blazing a Trail Toward the Energy Grid of the Future

A leading-edge operations center opens in New York The New York Power Authority (NYPA) has taken a huge step forward in increasing the efficiency of its operations with the opening of its new Integrated Smart Operations Center (iSOC), which harnesses the capabilities of state-of-the-art digitization technologies. The center, located in White Plains, N.Y., was officially […]

Say Hello to Hybrid Microgrids: Renewables, Storage, Diesel, and Intelligence

When is a D+ grade acceptable? The answer should be never. But that’s the state of the U.S. power grid according to the 2017 infrastructure report card issued by the American Society for Civil Engineers (ASCE). And the impact of this year’s catastrophic hurricane season only reinforced its vulnerability. Given the billions of dollars of […]

Exelon’s Digital Transformation [PODCAST]

GE and Exelon announced a multi-year agreement to deploy GE’s portfolio of Predix software solutions across the energy company’s six electric utilities to further enhance reliability and efficient service to its more than 10 million customers. Exelon’s six utilities will use these advanced analytics to further strengthen transmission and delivery systems. POWER Executive Editor Aaron […]

In the past (arrows shown in blue), power has typically flowed from conventional generation source to consumer in one direction via alternating current (AC). The medium-voltage direct current (MVDC) solution system (arrows in green) could allow  for omnidirectional energy flows at larger distances. Courtesy: Siemens

Siemens Rolls Out MVDC Transmission System to Bolster Distributed Generation 

Siemens has launched a new direct-current (DC) transmission system for alternating current (AC) grids of between 30 kV and 150 kV. The medium-voltage system that can bridge distances of up to 125 miles is designed to help grid entities handle ever-growing volumes of power fed into the distribution system from distributed and renewable power. The […]
