Facing unprecedented lead times and skyrocketing costs, the transformer supply chain crisis threatens the backbone of the electric power industry, driving urgent calls for increased manufacturing capacity and innovative solutions. Can the industry rise to the challenge? For several years now, the power sector has frantically raised the alarm about an impending transformer supply chain […]

An array of technologies, both thermal and renewable, are being used in the design of microgrids, supporting distributed power generation across several sectors. The use of microgrids to provide reliable power for critical infrastructure is growing, and these off-grid installations also are becoming more prevalent as part of commercial and industrial (C&I) enterprises and residential […]

High-voltage power transmission systems are more important today than ever before because power generated at renewable energy sites in remote locations must often be transmitted to distant load centers. Several state-of-the-art projects being done around the world are reviewed below. The majority of major electric power transmission lines in the U.S. are 115-kV, 230-kV, or […]

In the U.S., regional transmission organizations (RTOs) and independent system operators (ISOs) are responsible for overseeing the reliable operation of the high-voltage transmission system within their respective regions. In other countries, transmission system operators (TSOs) perform similar roles. In most cases, the primary objectives of these entities are to ensure the reliable and efficient operation […]

As coal, gas, and nuclear plants are retired, and wind and solar resources are added to the power grid, stability can become a problem. Understanding the solutions that are available to help manage potential issues is important for decision-makers so they can select the best options for their system. Grid stability and system strength have […]

Dynamic line rating (DLR) enables utilities to unlock up to 40% additional capacity from existing infrastructure, allowing grid operators to rapidly increase energy throughput. This capability is crucial in today’s energy landscape, where the proportion of renewable energy sources is quickly expanding, and the existing aging infrastructure cannot support this growing demand. Operating power lines […]

The future of energy may depend on technology with roots in the video game industry, by a company founded more than 30 years ago that wanted to use accelerated computing to improve the look and feel of the gaming experience. Jensen Huang, NVIDIA’s CEO and president since co-founding the Santa Clara, California-based company in 1993, […]

The utility industry is an unsung hero for nearly every community—until the power falters. A prime example is the extreme weather that passed through much of the central U.S. this spring. In Houston, where my company is based, we recently experienced severe storms that left around a million businesses and homes without power. These acts […]

SAIDI (System Average Interruption Duration Index) and SAIFI (System Average Interruption Frequency Index) are widely used reliability indices that measure the performance of power distribution systems. SAIDI represents the total duration of interruptions for an average customer over a given time period, typically a year. It is calculated by taking the sum of all customer […]

Global energy company GE Vernova and Seatrium Limited, a Singaporean state-owned group, said their consortium has been awarded a third contract by Dutch transmission system operator TenneT for construction of a 2-GW high-voltage direct current (HVDC) electric offshore transmission system in the Netherlands. The groups on June 10 said construction is set to begin this […]
