48 Hours Without Power at Home

Today’s power grid is an absolutely amazing feat of engineering and the United States grid is about 99.9% reliable. But when that .1% happens, it costs power users billions. We’ve discussed Lawrence Berkeley National Laboratory’s study on the economic impact of power outages before, which calculates estimated outage costs for electricity customers. Residential customers experience [...]

Can Your Transformer Protective Device Clear the Most Common Type of Faults?

Protecting power transformers in distribution substations is a critical power system application. Power transformers are expensive assets with long lead times—and the need to remove a power transformer from service to repair damage can have a big impact on power reliability for downstream customers. For these reasons, it’s critical to select an appropriate primary-side protective [...]

Renewable Energy is in the Power Mix for Africa

This spring I attended African Utility Week 2014 in South Africa. While there were many different conversations around topics such as renewable energy and energy distribution in the region, a key discussion point was the need for further education within the energy industry about new technologies. In particular, there is a need for greater understanding [...]

The Foundation for Reliable Power? A Reliable Power Grid

Power outages in the U.S. have been on the rise for the past three decades, according to one recent article. The U.S. power grid today loses power 285 percent more often than it did in 1984, costing billions of dollars every year. Weather-related power disruptions are particularly costly—a concern as the Atlantic hurricane season is [...]

Removing the Hurdles to Energy Storage Adoption

It seemed no small coincidence that the Energy Storage Association’s 2014 annual conference took place the same week that the U.S. EPA announced new proposed rules to reduce carbon emissions. Energy storage will play a significant role in reducing carbon emissions. Consider some of the ways that energy storage can help: It makes it practical [...]

Planning for More Renewables? We Need to Plan for More Energy Storage, Too

You likely heard the biggest news in our industry last week—namely, that the U.S. Environmental Protection Agency has proposed new rules to reduce greenhouse gas emissions from power plants. Under the proposed rules, states would have some choice in how they meet the proposed rules. But it seems certain that renewables will be a big [...]
