Reports abound of homeowners and businesses unplugging from the power grid and opting instead to generate and store their own electricity. Such grid defections may make sense in places where electricity rates are sky-high or service is spotty. But for just about everywhere else, it’s far more sensible to do the very opposite: interconnect regional electricity networks to form a globe-spanning supergrid.

What makes this idea so compelling are the major strains on today’s power grids: soaring energy demand in fast-growing megacities; rapid expansion of carbon-free but intermittent wind and solar power; and the ever-increasing need to secure grids against electronic and physical attacks. The smaller and more isolated a power network is, the more difficult it is to maintain the nearly instantaneous balance between electricity supply and demand.

Electric utility infrastructure habitually falls prey to overgrown Right-of-Way, high winds, and harsh weather. Impactful events causing outages are increasing in frequency, and need to be endured without major disruptions in electric service. This webinar will discuss the application of covered aerial conductor to "harden" the electric utility grid so that unpredictable events don't result in unsustainable outages.
