Hawaiian Utility Fights Solar Industry Over Private Installations

U.S. Utilities Make Their Own Plays for Control of Distributed Power

Solar Transportation

When you drive an efficient new vehicle (hybrid or electric for example) off the showroom floor, it has already traveled 30,000 miles or more (the energy it took to make the car). Oil will soon be hard to come by and expensive. ()

, using panels right on the guide-way of automated transportation networks such as is being designed by the City of San Jose. Honolulu could take a lesson from Silicon Valley. To learn more, come to the fourth international podcar city conference in San Jose this October.

HECO

We are working on solar power for schools under a 2X model whereby 1X solar flows to the school while 1X additional goes back to the grid under a PPA.

A key pilot program by the California Sacramento Utility District (SMUD) on the Anatolia residential district with several hundred homes over 2 years debunks the theory that FIT will create destabilization of the grid.

The study showed that at peak power hours, no more than 3.2 percent from solar was fed back to the grid under carefully monitored conditions. The Anatolia project converted several subdivisions into green sustainable technology including solar.

Engineers state that if the net added load from solar coming back to the grid would reach 15 percent, then destabilization might be an issue. However, this number is fictional with no supportive data - just a supposition.

The key technological question is the additional load on the transformer on a pole or in a vault that might cause overheating when temperatures are high. Sacramento measured the results during days when the temp was above 100F for 2 weeks

HECO is going after

HECO is going after distributed renewables in the name of doing buisiness with large centralized renewables. Specifically large windfarms proposed for Lanai and Molokai.

Wind Energy's Ghosts

PFffft. There are direct

PFffft. There are direct sources of renewable power. There are also other options like heating oil, moving water, or utilizing batteries to back up to smoothen the load to the grid. Stating we need dirty fossil fuels is blatantly wrong.

While HECO's knee-jerk

While HECO's knee-jerk reaction to the issue of solar power's intermittent generation is way overboard, it does bring up a good point. We will always have to use some fossil fuels to create electricity or we will not have power at night. Unless we can find an efficient way to store power in a huge battery, night-time energy generation will always be an issue.
