Mass-production techniques + aggregated demand among building owners to cost-effectively retrofit buildings to a net-zero energy standard

The Challenge of Scaling Up Energy Retrofits for Buildings Most building energy retrofits are one-off affairs. “We need an Amazon” in the market, says one architect. By Tom Konrad, GTM, July 19, 2019 Getting to the root of the problem.8 It’s almost always easier and cheaper to build an energy-efficient building in the first place than retrofitting existing structures. But …

10,000 aggregated distributed energy assets take advantage of a software platform that connects them and helps decide when to charge and when to discharge

“To take advantage of when to charge and when to discharge —  and bid into the wholesale market — you need a software platform to connect all of the batteries together,” Sternberg said. The software platform monitors battery telemetry — the current state of charge and the battery’s capacity to offer power to the grid or take from the grid. An …

Energy resilience planning on a local/regional basis in Colorado

Energy efficiency and solar coupled with storage are both examples of resilience options that can provide benefit year-round. While end-use efficiency does not in itself provide power during an outage, it allows for more critical services to be delivered with limited generation capacity. Year-round, increased efficiency lowers energy demand and costs. On-site solar and storage can provide backup power when the grid goes …

Interconnect Microgrids for Greatest Benefit. Also, What Electrification of Transportation and Buildings Means to Microgrids: Interview

Energy-as-a-service or microgrid-as-a-service, the approach allows customers to secure the benefits of microgrids — reliable local power, cost management and clean energy — without taking on the risk. Typically, the host pays only a fee for electric service while a third party develops, builds and operates the microgrid. “Energy as a service is the story of energy smartly procured, locally produced, …

Time of use rates can halve increase in electricity load from EVs. Storage makes the rest a benefit through V2G support

Looking into the future, the most exciting technologies are vehicle-to-grid (V2G), which allows EV batteries to discharge energy to the grid, and smart charging, which uses algorithms to optimize charging times. Implementing these technologies could turn EVs into a valuable asset for the grid — not only would smart charging minimize the negative effects of increased electrical consumption, but V2G …

The State(s) of Distributed Solar + Should Utilities Be Buying New Gas Plants?

The State(s) of Distributed Solar — 2018 Update BY MARIE DONAHUE | DATE: 12 MAR 2019  2018 Year-End Update Renewable energy continued to expand across the country in 2018. This expansion in renewable energy complements a growing number of states, utilities, and cities that have set ambitious goals to transition to 100 percent renewable and carbon-free power generation. New solar photovoltaic capacity, including from small-scale distributed solar …

2019: the year of orchestrating flexible resources, diverse sources, batteries and demand/non-wires alternatives

“2019 is going to be the year of orchestrating flexible resources, both on the residential and C&I side,” said Elta Kolo, research manager for the Grid Edge team at Wood Mackenzie Power & Renewables. “You’re going to see increasing diversity in the resource mix that’s being orchestrated.”  This development is part of a long-awaited shift from old-school, unidirectional demand response signals …

What To Do About DERs: ISO says, “Historically, we have forecast demand for power, and dispatched supply. In the future, those roles will reverse.”

The most realistic vision for a decarbonized power system: lots of large-scale solar and wind generation, balanced by a mix of large-scale storage and myriad flexible, distributed energy resources (or ‘DERs’). (I won’t go into detail about how cheap these renewable energy sources have become — for more on that topic see GTM on that or Utility Dive here and here) If managed well, the burgeoning …

Clean Energy Through Urban Action – PUSH Buffalo

Clean Energy Through Urban Action – PUSH Buffalo, by Carolyn Fortuna in Clean Technica, February 23rd, 2019  “It’s an interesting time to be alive,” Rahwa Ghirmatzion, PUSH Buffalo‘s executive director, began during a recent interview with us at CleanTechnica. Mobilizing residents into vibrant neighborhoods with safe, reasonably-priced housing and local hiring opportunities, the organization has many successes, and its ongoing collaboration with the Solutions Project to power the …

The World’s first renewable island – when a community embraces wind power

RapidTransition.org story posted 4 February 2019. See lessons The Danish island of Samsø went from being entirely fossil fuel dependent to becoming the World’s first 100% renewable island, in under a decade. In 1997, the Danish Government launched a competition to develop a model renewable energy community, in order to prove that the country’s Kyoto climate target to reduce carbon emissions …
