GRID was established in accordance with the Energy Commission Act, 1997 (Act 541) and the Volta River Development (Amendment) Act, 2005 Act 692, which provides for the establishment and exclusive operation of the National Interconnected Transmission System by an independent Utility and the separation of the transmission functions of the Volta River Authority (VRA) from its other activities within the framework of the Power Sector Reforms.

Perilous Waters

Perilous Waters

“Peligro,” the sign reads—danger. Despite this warning, people have filed through gaps in fences and have waited patiently to fill buckets, jugs, and bottles with water from a spigot on an abandoned lot, the Washington Post reports. In the aftermath of Hurricane Maria, citizens of Puerto Rico are in desperate

Benefits of Community Microgrids

Benefits of Community Microgrids

However they are defined, everyone agrees community microgrids provide benefits. Centralized utility systems and aboveground distribution lines expose customers to regional and local outages, “and while they are highly reliable, centralized utility grids can’t ensure local resilience,” notes Peter Douglass, project manager for the Microgrid Institute, a collaborative organization supporting global development of microgrids and distributed energy

A Silver Lining After the Storm

A Silver Lining After the Storm

The images of Hurricane Maria’s aftermath in Puerto Rico are shocking—trees stripped of their foliage, splintered buildings, drowned cattle, and the twisted remnants of cars. The destruction is unfathomable.

When the hurricane’s winds and torrential rains hit the US territory on September 20, they not only destroyed buildings and flooded the

Microgrid Technology to Improve Energy Security and Sustainablity

Nearly 25 years ago, Caterpillar opened a proving ground about 30 miles southwest of Tucson, AZ. The facility consists of large open-air test areas, where Caterpillar conducts field trials of many of its large mining equipment before being brought to market. The proving ground site also includes workshops and an office building.

While grading and excavating equipment continues to get better and better, the smart equipment, software, and systems that support this equipment and improve its safety, efficiency, and productivity are also getting better.

Measuring Earthwork Volumes

Formulas and methods for determining the volumes and areas of regular shapes and surfaces go back at least as far as ancient Greece. Pythagoras and other mathematicians determined the formulas that are still used to calculate the volumes of spheres and pyramids, as well as the areas of curve conic

The Power Industry’s Patchwork Quilt

The Power Industry’s Patchwork Quilt

My great-grandmother was a quilter. She pieced together colorful fabric scraps to create mosaic patterns on each blanket. I remember her dismay one day after tacking a design together when she discovered an additional set of pieces that needed to be included. After a moment of reevaluation, she cut the
