Can a Flow Battery Steal the Throne From TEP’s 4.5-Cent Solar-Plus-Storage PPA?

Electricity retailer Direct Energy started winding down its residential solar installation business last week.

Direct Energy Solar will continue to operate its commercial business and plans to maintain its existing fleet of rooftop installations. The pivot away from residential affects approximately 330 employees, making up a considerable portion of the company's overall solar unit. Those employees have been given an opportunity to seek other jobs within the broader company.

Direct Energy, a subsidiary of Centrica, appears to have been the last national electricity retailer with its own residential solar business.

NRG Energy closed its rooftop solar installation business in February. And earlier this

Hawaii Utility’s 100% Renewable Energy Plan Gets the Green Light

Signing the cheapest PPA is like conquering the Iron Throne: Before you have time to enjoy the accomplishment, someone's on their way to take it from you.

In May, NextEra Energy Resources secured a 4.5 cent per kilowatt-hour solar-plus-storage PPA with Tucson Electric Power. That's low for just solar, but the 100 megawatts of generation will come backed by 30 megawatts of four-hour duration energy storage. The system is set to run by the end of 2019.

Now, a usurper approaches. Not from the well-heeled realm of lithium-ion, where the cash flows and the revenues stack, but from the rugged

The term “distributed energy resource management system,” or DERMS, is used to describe a wide array of software platforms serving a number of functions, from controlling and aggregating fleets of behind-the-meter energy assets, to enabling utilities to integrate these distributed energy resources into their grids. 

But according to GTM Research’s newly released North American DER Management Systems 2017 report, a true “enterprise DERMS” platform -- one that includes all of the above, without kludgy multi-vendor integrations, and outside the realm of pilot projects -- doesn’t exist today. 

“This isn’t about interconnection or hosting capacity analysis, operations and maintenance, or long-term management of distributed energy resources

Hawaii Utility’s 100% Renewable Energy Plan Gets the Green Light

A decade may not seem like a remarkably long time to have been in business, but it certainly is in the world of rooftop solar. In an industry known for its ups and downs, residential solar installer Sunrun hit the commendable milestone last week of 10 years in operation.

Executive Chairman and co-founder Ed Fenster and CEO and co-founder Lynn Jurich launched Sunrun in 2007 from an attic in San Francisco and signed the company’s first customers from a booth at a county fair. Since then, Sunrun says it has built more than $2.5 billion in solar systems, saved customers more than $150 million on their energy

Hawaiian Electric Companies, tasked with powering multiple island grids with 100-percent green energy by 2045, has finally secured regulator approval for a plan to get there -- as long as it includes customers and third parties in the mix. 

On Friday, the Hawaii Public Utilities Commission approved (PDF) the utility’s Power Supply Improvement Plan, or PSIP, a sprawling document that contains the recipe for hitting the state’s 100-percent renewables mandate by 2040, five years ahead of schedule. 

It’s an important milestone for the utility, which has seen two previous proposals rejected by the PUC, first in 2015 for being too vague, and then in

Despite the advantages, cutting edge housing doesn't always excite potential buyers

Five years ago, Brackett Estates was a net-zero community in Wells, Maine, that existed mostly inside the head of builder Jesse Ware. He and his business partners had a single house, a two-story modular packed with insulation and powered by rooftop solar panels — and a plan to build 25 more of them for a new generation of homebuyers who wanted green, energy-efficient housing.
