      SDG&E Approved for 5 New Storage Projects Totaling 334 MWh

      The California Pubic Utilities Commission (CPUC) has approved five new storage projects totaling 83.5 MW / 135 MWh and a demand response program capable of contributing 4.5 MW as part of San Diego Gas and Electric's plan to add more renewables and improve grid reliability. Each of the lithium-ion battery storage facilities in San Diego and Orange counties is a four-hour battery to be developed by a different company. OhmConnect was tapped to manage the demand response program.

      Colorado Integrates Storage into Utility Planning Process

      Colorado Democratic Gov. John Hickenlooper signed legislation on Friday to encourage the installation of energy storage in the state and to integrate storage procurement mechanisms into utilities' long-term planning processes. House Bill 18-1270, also known as the "Energy Storage Procurement Act," sets a deadline of Feb. 1, 2019, for the Colorado Public Utilities Commission to develop procurement rules. Utilities will be able to file applications for rate-based projects by May 1, though they cannot exceed 15 MW.

      NY Latest Renewables RFP to Spur $1.5B Investment

      New York announced its second large-scale renewables solicitation on Wednesday. Gov. Andrew Cuomo (D) estimated that it could drive up to $1.5 billion in green energy investments. The bids are expected to support the generation of 1.5 million MWh annually — roughly the annual energy consumption of 200,000 homes — contributing to the state's goal of reaching 50% renewable energy by 2030.

      Colorado Senate Approves Second Storage Bill, Waits on House

      The Colorado Senate on Monday voted 26-9 on third reading to approve HB18-1270, which directs the development of mechanisms to enable investor-owned utilities to acquire energy storage systems, while restricting their size to 15 MW. Because amendments were added on the floor, it will need to be approved again by the House. The bill would direct state regulators to "establish mechanisms" for investor-owned electric utilities to procure energy storage systems. Some criteria would need to be satisfied, however.

      New Hampshire Utility Proposes Virtual Power Plant with Tesla Powerwalls

      A proposal to install 300 Tesla Powerwall batteries in homes in Lebanon, N.H., is just the latest example of utilities turning to distributed storage, as well as the growing battle to supply these Virtual Power Plants (VPP). Valley News reports Liberty Utilities tapped Tesla to supply the batteries, but the proceeding has grown as SunRun has called for a competitive bidding process to supply the batteries. The Liberty Utilities pilot will eventually be expanded to 1,000 customer homes.

      California Regulators Broaden Rules for Energy Storage

      The California Public Utilities Commission last week approved new market rules for energy storage aimed at enabling the resources to stack incremental value and revenue streams through the delivery of multiple services to the wholesale market, distribution grid, transmission system and other venues. Regulators say the previous rules meant battery assets were unable to realize their full economic value, but the changes will help ensure correct pricing and improved economic viability.

      Ny ISO Plan Sees Storage in State's Wholesale Markets by 2020

      The New York ISO yesterday released a new report, "The State of Storage," kicking off the process of developing a model for energy storage resources to participate in the state's wholesale markets. The roadmap lays out a three-phase plan that focuses on storage integration, optimization and aggregation. Bringing storage into wholesale markets could be accomplished by 2020, according to the timeline.

      Rhode Island Grid Mod Plan to Focus on Renewables Integration, Cost Control

      Rhode Island energy officials say the state's efforts to modernize its electric grid will be a "complex undertaking" as well as a "huge opportunity" that ultimately will help control costs, while creating a more resilient and cleaner system. The state's energy agencies Nov. 17 submitted to Gov. Gina Raimondo (D) a report outlining steps to overhaul Rhode Island's electrical grid, with a focus on controlling costs, integrating more green power, improving service and overhauling utility incentive models.

      Hawaii Expands Rooftop Solar, Storage Options for Residential Customers

      The Hawaii Public Utilities Commission last week approved two new solar programs for customers interested in rooftop panels or energy storage in an effort to expand those resources while also clarifying the terms of existing programs to provide greater certainty. The PUC approved a “Smart Export” program which offers a new option for customers installing rooftop solar combined with battery storage. Under the new program, a customer’s energy storage system will recharge during the daytime with energy captured from their solar system and use that energy at night or export it back to the grid.

      Schneider Electric to Build Microgrid at Massachusetts HQ

      Microgrids are becoming an increasingly popular alternative to traditional electricity service from the utility grid for big energy consumers. Among other benefits, microgrids can enhance reliability, provide grid services, and add to sustainability efforts. Schneider announced the microgrid this week at DistribuTECH. "Being in the space, it made sense for us to figure out how to create our own microgrid," Senior Vice President Andy Bennett said, as reported by Renewable Energy World. The system is both a technical experiment as well as an economic one, with the aim of operating as a so-called "island" of electrical power in case of long power outages.
