In many ways, islands in the United States are at a natural disadvantage when it comes to their energy portfolio.

In Ghana, utility officials were working around the clock to trim energy demand through various demand response measures to ensure that the nation could keep televisions on during the game. In addition to purchasing 50 megawatts of electricity from neighboring Ivory Coast, Ghana also adopted a common peak demand reduction strategy (one that was also used by Texas last winter went electric heating demand ballooned): energy officials reached a deal with large industrial users to slow their energy-intensive activities.

However, for many utility companies, the most difficult peak events have already begun: across the US, a severe polar vortex has presented a series of strenuous challenges for the electric power grid.

This past week, extreme low temperatures have sparked periods of exceptionally high electricity demand, known as “peak demand events,” that have shattered winter records throughout the country.
