Unanswered Questions about the Public Rooftop Revolution

At the beginning of June 2015, ILSR released its Public Rooftop Revolution report, which described how cities across the nation put the shine on municipal rooftops with more than 5,000 MW of solar. That 5,000 MW is as much as one-quarter of all solar installed in the U.S. to date — and many cities could install solar little or no upfront cash. The energy savings would allow cities to redirect millions to other public goods.

As North Texas Grows, Let's Grow it "Solar Ready"

Building a new home, or know someone who is?  Then make sure the builder designs and builds it "Solar Ready"!

North Texas continues to grow.  According to various estimates, the population could double over the next decades and along with that a million new homes could be constructed.  Providing clean energy will be one the key challenges for the region. However, with this new home construction, comes the great opportunity to leverage our local clean energy resource from the sun!

Aggregate Net Metering

placeholderFor larger electric customers, net metering has a hitch. In many states, the solar array (or other power generation) has to be attached to the same building (or meter) that the entity wants to offset. So if Building A has a great roof for solar but Building B is where all the energy is used, tough luck.

Kansas City’s Royal Effort to Solarize City Rooftops – Episode 25 of Local Energy Rules

Kansas City, MO, has neither the abundant sunshine nor high cost of electricity that have driven solar installations in other cities. Despite this, the city has close to 1.5 MW of solar in 59 separate installations on municipal properties. Thanks to utility rebates, two department leaders, and a unique opportunity that allowed it to access the 30% federal tax credit, the city was able to make solar work in an otherwise challenging climate of modest sun and low electricity prices.

Duking It Out Over Municipal Solar in Raleigh – Episode 24 of Local Energy Rules

There aren’t many solar success stories from the Southeast, making Raleigh, NC, stand out in a region with low-cost electricity and modest sunshine. With just over 2 megawatts of solar on public property––providing close to 7% of municipal building peak demand––Raleigh’s solar success comes despite state rules preventing city from buying electricity from any non-utility entity.
