Technology Corridor

A digital grid to the home, secured via a local fiber-optic network, could position utilities to fix power and telecom together.

Before billions are spent building new transmission lines to ensure reliable electric service, North American electric utilities should evaluate whether the alternatives-controlling demand and fostering distributed generation-might be more cost-effective and broadly beneficial.

That's what Bonneville Power Administration (BPA) suggested recently when it declared, "Before BPA decides to build a line, we want to make sure we have fully considered whether non-construction alternatives can be used. We want to look at all options, not just traditional construction."1

Two substitutes in particular merit exploration:

  • Demand response moves data between utilities and consumers so retail prices can reflect utilities' actual fluctuating costs, allowing consumers to react based on rational determinations of self-interest.
  • Distributed generation produces electricity near where it's consumed, often under consumer control and from renewable and non-polluting sources.

Both conserve-one by avoiding surplus production, the other by displacing excess transmission. Both enlist private individuals and entities as transactional partners and invite energy from solar and fuel cells and windmills to become cost-competitive. During the next decade, the U.S. Department of Energy suggests that as much as 50 percent of all power locally consumed could be locally produced, stored, and coordinated with central generation via microgrids.2
