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 […]

The U.S. Senate has passed the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act, sweeping legislation that seeks to promote U.S. nuclear leadership, accelerate advanced nuclear technology development while preserving existing nuclear generation, bolster national security measures, and enhance regulatory efficiency to support new nuclear deployment. The Senate passed the bill on […]

A leading solar energy equipment provider announced construction of a new factory that will expand its U.S. operations. California-based Nextracker on June 18 held a ceremony to mark the second Nextracker-dedicated manufacturing line that Unimacts, a Las Vegas-based group, has opened in the past year. The new 160,000-square-foot facility in Sloan, Nevada, south of Las […]

Mitsubishi Corp. (MC), Takasago Thermal Engineering Co. Ltd. (TTE), Hokkaido Electric Power Co. (HEPCO), and Air Water Hokkaido Inc. (AWH) announced the signing of a joint development agreement to supply green hydrogen in Hokkaido’s Chitose area. Hydrogen can be produced by electricity and other sources of energy, and because it does not emit CO2 when […]

Lhyfe, a pioneer in the production of green and renewable hydrogen, delivered 350 kilograms of green hydrogen (Figure 1) to natural gas expert Géométhane, on June 13, for it to test injecting hydrogen into salt caverns at its Manosque site in the south of France. The injection, which was completed within the day, is a […]

Bill Gates’ nuclear innovation firm TerraPower has broken ground on the non-nuclear portion of Kemmerer Unit 1, a 345-MW Natrium sodium-cooled fast reactor (SFR) power plant. The groundbreaking on June 10 makes the federal demonstration project the first advanced nuclear reactor project to move from design into construction in the Western Hemisphere, the company noted. […]

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 […]
