Planning for distributed renewable energy

Gridworks excerpt: California’s AB327 added a new section to the Public Utilities Code, Sec. 769, to require utilities to submit to the commission by July 1, 2015, a distribution resources plan proposal, to identify optimal locations for the deployment of distributed resources.  Further, these plans should form the basis for utility investment requests in future general rate cases.  The bill …

Shout It From the Rooftops: Solar Delivers Far More Than Renewable Energy

Contrary to what many utilities would have you believe, rooftop solar users are givers, not takers, the author writes. GreenTechMedia, by Emma Searson, 5 Aug 2019 26 Thinking beyond the payback period. We often define the value of something, including our clean energy investments, through a very limited cost-benefit analysis: What are my expenses related to this new thing, and …

TerraForm Power invests in distributed solar portfolio to recycle capital from stabilized assets, plans to squeeze additional value from the new assets by offering tack-ons like storage and backup generation

7/19 GTM: The former SunEdison yieldco hopes to leverage the diverse 300-megawatt portfolio to sell additional services to commercial and industrial clients. TerraForm Power to Invest $720M in Distributed Solar Portfolio. By Emma Foehringer Merchant Brookfield-controlled TerraForm locks down more distributed solar. 3 TerraForm Power announced Monday it will take over ownership of a portfolio consisting of 291 megawatts of …

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 …
