    1. Duke Energy's Commercial Solar Business to Offer Energy Storage

      Duke Energy's Commercial Solar Business to Offer Energy Storage

      When Duke Energy, one of the biggest U.S. electricity providers, purchased its controlling interest in REC Solar, one of the biggest U.S. commercial solar developers, it created a $225 million fund for commercial scale solar development. With the federal investment tax credit for commercial solar expected to revert from 30% to 10% at the end of 2016, solar companies will need “scale and reach” to succeed, REC Solar CEO Al Bucknam told Utility Dive in February.

      Why Australia is a 'Proving Ground' for Solar-Plus-Storage

      What happens in Australia's solar and storage markets could be a valuable lesson for other countries, especially the United States. The rooftop solar penetration in Australia is among the highest in the world, with about 13% of homes in the country hosting solar panels on their roofs. Similar to Hawaii, the power sector is looking to Australia as an early test-case for how to deal with this level of solar penetration.

      Oregon Saddles up to Implement Trailblazing Energy Storage Mandate

      In the new year, the Oregon Public Utility Commission (OPUC) will convene a proceeding on the state's new energy storage law, which could produce a template for the rest of the nation. While Oregon's law is actually the second in the nation — California enacted a storage mandate in 2013 — sector stakeholders say the law is special in the guidance it provides to regulators on how to value energy storage technologies.

      Ice, Ice Energy: The Hot Market for Cooled Liquid Energy Storage

      Margins are good for the two dominant providers of cooled liquid storage, which uses low-priced nighttime electricity to freeze or cool a liquid and then utilizes the chilled liquid to help offset electric air conditioning loads when power prices peak during the day. “We are generally earning margins in the 25% to 30% range and that is unusual in the storage industry,” said Ice Energy CEO Mike Hopkins. “For most of the companies, especially in the lithium ion space, the cost is not competitive yet and they have to price their product at no margin.”

      Report: Global Grid Storage Hits 1 GWh Milestone for 2015

      So far this year, the grid storage market has more than doubled from the totals booked in 2014, even though not all of the 1,090 MWh installed in 2015 will be commissioned this year. In terms of technology, much of the recent growth in the storage market has been dominated by the increasing market penetration of Li-ion batteries. Stationary Li-ion applications have grown sharply, but that growth is dwarfed by the growth of Li-ion batteries for electric vehicles. Plug-in and hybrid vehicles accounted for 2.3 GWh of Li-ion batteries in second-quarter 2015, according to Lux Research’s Automotive Battery Tracker.

      It is not so much the concept of bundling or pricing, which always varies by location, that is being tested on Kaua’i. More than that, say storage backers, the significance is held in the way the project was packaged and sold. The Kaua’i project is a “test for this kind of deal structure,” says Matt Roberts, executive director of the Energy Storage Association. The Kaua’i deal has the potential to combine least cost and performance in a PPA, that is something “a lot of utilities want to see,” Roberts said.

    10. Ohio Touts Largest Energy Storage Project Thanks to Renewables Freeze

      Ohio Touts Largest Energy Storage Project Thanks to Renewables Freeze

      Once completed, the storage project in Minister, Ohio, will be one of the largest in the state. According to PV Magazine, the combined solar+storage facility will be the largest of its kind in the United States. But the irony here is that the storage aspect wasn't originally planned. The energy storage part of the project was added when Ohio began considering changes to its SREC requirements. Last July, legislators passed a bill that terminated a requirement that half of the state's SRECs aimed at its renewables goals be generated in the state, while freezing the state's renewable energy portfolio standard for two years.

    11. Residential Energy Storage: The Industry's Next Big Thing

      Residential Energy Storage: The Industry's Next Big Thing

      Enabled by falling battery prices, heralded as essential to renewables and mandated by progressive regulators, utility-scale storage projects have been widely viewed as the key technology which will help bring the nation's utility grid into the 21st century. But amid all the hullabaloo surrounding larger deployments, a smaller segment has been gaining steam and could have an even larger impact on the grid. Residential storage, once the stuff of expensive pipe dreams, has gone from feasible to home feature, with developers bringing out a range of products and offerings. Many are tied to home solar systems, but there is also growing interest in stand-alone storage for battery backup, aggregation and demand response.

      Duke Simplifies Microgrid Development Process for NC Fire Department

      Duke's new microgrid, which the company has been operating since July, is relatively small — it operates off a 50 kW battery the utility installed at the McAlpine substation. But the project's significance goes beyond just keeping the lights on at Station 24. Duke spent a year developing the microgrid using only standard utility components and writing the code in-house in an effort to reduce the time and cost needed to develop a microgrid.

      Inside Southern California Edison's Energy Storage Strategy

      Last winter, Southern California Edison sent the U.S. energy storage sector into a frenzy with a single announcement: It would purchase over 250 MW of energy storage in one fell swoop — more than five times the amount California regulators required it to do at the time, and easily the biggest single storage procurement to date. Nearly one year on from that historic proposal, what has SCE learned about storage—and what is its outlook for the future? Utility Dive spoke with SCE President Pedro Pizarro to find out.

      Inside the Nation's First Renewables-Plus-Storage Microgrid

      The grid was used to avoid some smaller outages, and then earlier this year the California Energy Commission awarded the utility a $5 million grant to expand, allowing it to interconnect with the nearby 26-MW Borrego Springs solar facility. That turned out to be a prescient investment. Borrego Springs' peak load is about 14 MW, and rooftop plus utility-scale solar give the community about 30 MW of generation. The batteries can store about 1.5 MW.
