As society contends with the impacts of climate change, we need to aggressively pursue strategies for reducing carbon emissions. Although states in the U.S. are taking a variety of approaches to greenhouse gas (GHG) reduction, and following an equally diverse set of timelines, most state-level GHG emission goals announced so far are fairly consistent—to reduce […]

The mid-February blackouts in Texas have raised a lot of questions about power grid reliability. While investigations into the underlying causes of the outages could take a while to complete, and I don’t

Reliability performance is core to the utility industry. Utilities strategically design and invest in their system to maximize reliability performance—traditionally measured by System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI), and/or Consumer Average Interruption Duration Index (CAIDI). These quantitative metrics largely drive utility investment decisions, shape strategic priorities, dictate regulatory approvals, […]

When evaluating resource adequacy requirements, many power companies and grid operators have used a methodology that originated more than 70 years ago. This probabilistic reliability approach has generally performed adequately through the years. It has generally evaluated loss-of-load events occurring at frequencies of one-day-in-10-years (1-in-10) to be acceptable in terms of system reliability. However, it’s […]

WACO, Texas — LineWise has introduced its TLL-500A Series 3 Triple Line Lifter for sub-transmission applications. Designed to support three phases of energized conductors between 34.5 kV and 72.5 kV, the product features all-new hydraulic articulation, allowing operators to easily rotate phases up to 90 degrees from horizontal to vertical orientation while servicing sub-transmission lines. […]

A sweeping climate proposal introduced by U.S. House Democrats on March 2 sets a stringent clean energy electricity mandate for power retailers nationwide, requiring they procure 100% of their power supplies from zero-emitting generation by 2035.  Among its slew of measures aimed at achieving net-zero emissions nationwide by 2050, the Climate Leadership and Environmental Action […]

Historically frigid temperatures across Texas forced 34 GW of generation—across all fuel types—off the Electric Reliability Council of Texas (ERCOT) system, prompting the grid operator to initiate rotating outages starting at 1:25 a.m. CST on Feb. 15. ERCOT said it expects outages will likely last at least through Feb. 16. This article has been updated […]
