Risks posed by geomagnetic disturbance (GMD) and electromagnetic pulse (EMP) events add challenges to an already complex power system environment. But they remain crucial to address. How prepared is the power grid to withstand these powerful natural and man-made disturbances? On the evening of May 10, grid operator PJM Interconnection activated a rare geomagnetic disturbance […]

The need for more reliability and resilience of power delivery, both in the U.S. and worldwide, has utilities and grid operators looking for solutions to the challenge of bolstering the electricity supply. Electric grid infrastructure, both in the U.S. and other parts of the world, needs an upgrade. Increased power demand from energy-intensive industries such […]

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 […]

Masdar, the Abu Dhabi-based renewable energy major, said it has agreed to buy Greece’s Terna Energy in a €3.2 billion ($3.4 billion) deal. The agreement signed June 20 is one of the largest renewable energy transactions in the history of the European Union. Masdar—also known as Abu Dhabi Future Energy Co.—said Thursday it had a […]

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 […]

As the solar industry matures, pressure for asset owners to deliver higher returns continues to mount.  Not surprisingly, so has the demand to improve operations and maintenance (O&M) efficiency – the single largest component of a utility-scale solar asset’s post-construction budget. Whether an asset owner performs O&M in-house, outsources to a third-party, or utilizes a […]
