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 […]

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 […]

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 […]

Pacific Gas and Electric Co. (PG&E) and its remote grid program received an honorable mention in the Energy category of Fast Company’s 2024 World Changing Ideas Awards. Winners were announced on May 14, highlighting fresh sustainability initiatives, cutting-edge artificial intelligence (AI) developments, and other creative projects that are helping mold the world. PG&E is one […]

It’s no secret that the U.S. electric power system has undergone a remarkable transition that continues today. Coal-fired generation, which was the leading source of power generation during the 20th century, often providing more than half of the country’s electricity supply, fell to about 16.2% of the mix in 2023. Meanwhile, the U.S. solar market […]

It’s no secret that power grids around the world need to expand to accommodate more renewable energy and the so-called “electrification of everything.” The latter, of course, refers to the growing trend of using electricity to power various sectors and applications that have traditionally relied on fossil fuels, such as natural gas or petroleum-based products. […]

The Solar Energy Industries Association (SEIA) reported in March that the U.S. solar industry installed 32.4 GWdc of capacity in 2023, a remarkable 51% increase compared to 2022. It was the industry’s

There are numerous articles and studies warning of the fragile nature of America’s electric grid. The vulnerabilities will only become more apparent as we continue to undergo a fundamental shift in how
