With record high temperatures and wildfires gripping the West, utilities have asked residents to cut down on power usage to reduce the strain on overburdened systems. As we’ve seen following countless crises, the U.S. energy grid is being pushed to its limits. Fortunately, a $1 trillion infrastructure bill is on the horizon, and with it, a significant opportunity […]

The proliferation of renewable energy is necessary for communities and countries to meet their goals of reducing carbon emissions, but it also presents new challenges for those managing power distribution. Much of the world’s renewable energy is now generated and stored by distributed energy resources (DERs), such as residential solar panels, batteries, and electric vehicles […]

Energy companies continue to work on providing solutions to optimize the power grid, part of their efforts to support the integration of renewables and help ensure the reliable delivery of electricity. Such systems are part of the digital transformation of power generation, bringing increased flexibility to the power supply, supporting faster power restoration after outages, […]

The way we generate and distribute electricity has become a Rubik’s cube for power companies, regulators, and consumers. The need to reduce carbon emissions linked to climate change by investing in renewables is acknowledged by most experts. At the same time, recent unusual weather events have demonstrated that there is also an urgent need to […]

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 […]

While not a new occurrence, in recent years wildfires have wreaked havoc across the western U.S. We have also seen Mother Nature batter coastlines and landscapes around the globe, and the ever-mounting pace of

2020 was a lot of things, most of them sombre. However, there is one positive way I believe we in the distribution grid sector can describe the year, as an inflection point. In years to come, we may well look back on 2020 as the year when terms like “energy transition” and “digitalization” finally began […]

Electricity transmission network operators are being tasked with adding more renewable energy resources to the power grid. The use of static VAR compensators (SVCs) is growing as a means to control voltage
