Regulatory Reform Needed for Transmission Investment, Renewables Integration

April 6, 2015 by Max Luke

Limited transmission infrastructure is one of the largest obstacles to the deployment of renewables in the U.S. Many of the best wind and solar regions are far from areas of high electricity demand. Bringing electricity from these regions to load centers often requires additional transmission investments.[read more]

Death of the PPA: Is it Time for a New Business Model for Renewable Microgrids?

Microgrid Business Models

Supporting the growth of renewable energy through implicit or explicit subsidies has made sense in order to allow the sector to achieve critical mass and for technologies to mature. However, the cost of this support has been paid by power consumers and taxpayers.[read more]

Here Comes the Sun: How California is Bringing More Renewables to the Grid

California Renewables Grid Integration

Not content with setting a Renewable Portfolio Standard that ends at 2020, Governor Jerry Brown and state legislators are pushing for California to get 50 percent of its energy from renewable resources by 2030. California must build a system that is largely based on renewable electricity, like wind and solar.[read more]

Queensland Utilities Extend an Olive Branch to Solar Energy Innovators

February 21, 2015 by Nigel Morris

Whilst I often call a spade a spade and generally suffer from immense frustration with utility attitudes to solar, I have to give credit where credit is due. The next time you bump into the CEO’s of Queensland’s Ergon Energy or Energex, shout them a beer and thank them.[read more]

Buildings, Renewables, and Grid Integration

Grid operators may have a new ally in their efforts to integrate renewables and regulate the frequency of the grid: buildings. Variable-speed drives used to run heating and cooling systems can be modulated in response to signals from grid operators, helping keep the frequency of electricity flowing across the grid.[read more]

SolarCity, Nest to Energy Regulators: Open the Grid

October 23, 2014 by Jeff St. John

Rooftop solar, behind-the-meter batteries, smart thermostats, home automation. All are sources of energy, capacity, and reliability for the power grid. So say the engineers who’ve built them -- and so say the customers buying them. Now if only the regulators would move as fast as the engineers and customers.[read more]
