Utility Streetlighting Retrofits

Getting to “yes” with cities and neighborhoods.

Xcel Energy Colorado envisioned a straightforward plan: Street by street, city by city, in a logical progression over five years, they would replace High-Pressure Sodium streetlights with Light-Emitting Diode lamps. But that’s not what happened.

Economy of Small

How DG and microgrids change the game for utilities.

Energy microgrids have emerged as more than just a curiosity. The technology is improving, costs are falling, and developers are lining up to build projects. How will microgrids overcome the substantial challenges that stand in their way?

Energy Efficiency's False Hope

Only behavioral change will reduce energy consumption.

Standards and technology don't reduce energy consumption, despite the claims of efficiency zealots. Real energy savings only come through behavioral change.

Scratching the Surface

A 2013 retrospective on ‘Saving Gigabucks with Negawatts’ (1985)

The basic conclusion of “Saving Gigabucks with Negawatts”—that big thermal plants are obsolete—has proven true, as has its call for flexibility and strategic risk management. But the big issues now are no longer about marginal costs; they’re about the very nature of the electricity enterprise.

Demand Growth and the New Normal

Five forces are putting the squeeze on electricity consumption.

It’s tempting to attribute the recent slowdown in electricity demand growth entirely to the Great Recession, but consumption growth rates have been declining for at least 50 years. The new normal rate of demand growth likely will be about half of its historic value, with demand rising by less than 1 percent per year. This market plateau calls for a new utility strategy.
