Disrupting the Status Quo…  Thinking Out of the Box

By Malcolm Metcalfe on May 4, 2017 8:58:22 AM

A few days ago, I listened to a group of environmentalists on the evening news protesting a plan to build a new bridge that would solve traffic congestion and make it easier for people get in and out of a local large city. The protestors wanted the money spent instead on public transit, claiming that this options had not even been examined, and arguing that their solution would solve the transportation problem without requiring construction of new infrastructure.

I looked more closely at both alternatives. The government and the consultants retained to propose solutions to the problem had advanced several standard options, all of which revolved around either a bridge or a tunnel, while the environmentalists had extended the options by one – adding public transit as a means to achieve a similar result.

This seemed logical until I started thinking about the need to add one other criteria to the equation: the need to reduce carbon emissions.

Renewable curtailment: one symptom of grid troubles

This past March, Chinese energy regulators put the brakes on further deployment of wind-energy projects in Mongolia during 2016. Why? Call it too much of a good thing. China, now the world leader in solar and wind installations, doesn’t have the transmission infrastructure necessary to transport electricity from the windswept Mongolian steppes to the power-hungry cities that need it.

During 2015, China installed some 33 gigawatts of wind turbines, which was more than half of new wind installations worldwide. But, in the same year, government statistics show “33.9 billion kilowatt-hours of wind-powered electricity was wasted … equivalent to the electricity consumed by 3 million American households a year,” according to an article published by InsideClimate News. ”That was about 15 percent of China's total wind power generation, up from 8 percent a year earlier.”

Distributed intelligence: You can’t really be smart without it

By Malcolm Metcalfe on Dec 17, 2015 1:14:45 PM

Not long ago, one of the largest electric utilities in California told me they have 180,000 generating sites, and they expect this to almost triple by 2025. That’s just one of many reasons I believe no grid optimization can truly occur without distributed intelligence and control in grid-edge devices.
