      The Promise and Challenge of Scaling Lithium Metal Batteries

      While lithium-ion batteries are undergoing an historic scale-up, researchers are also hard at work looking for what battery technology might come next. A big battery breakthrough could lead to electric cars that could drive longer on a single charge and are safer to operate. Better batteries for the grid could store more energy, enabling the deployment of more wind and solar. “There’s a worldwide race for these kinds of concepts,” said Paul Albertus, program director for ARPA-E, the Department of Energy program that focuses on early-stage, potentially big-impact energy research.

    4. US Wind + Storage: The Business Case

      US Wind + Storage: The Business Case

      As renewable energy continues to disrupt wholesale markets, energy storage has potential to exploit volatile energy prices by buying low and selling high, allowing a wind farm to shift its energy from periods of low prices to take advantage of spikes. As a result, announcements of wind plus storage hybrid systems are ramping up as these systems become more flexible and can accommodate a wide variety of renewable generation. However, wind energy’s less predictable output and its eligibility for the production tax credit and investment tax credit make the value proposition for paired storage less clear than it is for solar.

      The UK Could Install 12 Gigawatts of Energy Storage by 2021

      Britain could have a 12-gigawatt battery market by 2021, according to a parliamentary policy group. The paper was written by the U.K. Renewable Energy Association (REA) and an All-Party Parliamentary Group (APPG) on Energy Storage, an interest group made up of members of the House of Lords and House of Commons. Hitting that 12-gigawatt target will require major policy support, however.

    8. How California's New Time-of-Use Rates Will Affect C&I Customers Considering Solar PV

      How California's New Time-of-Use Rates Will Affect C&I Customers Considering Solar PV

      On December 1, San Diego Gas & Electric became the first of California’s investor-owned utilities to implement a new time-of-use period that shifts the peak period later into the evening, to align with the "head" of the duck curve. Commercial, institutional and industrial customers in SDG&E territory are subject to some of the most expensive demand charges in the country, making it an attractive market for demand-charge management. Unlike residential customers, many non-residential customers are subject to demand charges that are billed based on the facility’s highest monthly demand (measured in kilowatts), which can often exceed half of their total monthly utility bill. An energystoragesystem optimized for demand-charge management can reduce demand charges by forecasting when the load will spike and then discharging the energy storage system to mitigate the peaks measured by the utility meter.

      The 10 Stories That Defined Energy Storage in 2017

      The industry stepped up with two major, high-speed deployments to resolve grid emergencies. Utility-scale projects got bigger and longer lasting. Major international conglomerates bought up storage startups. And all the major solar developers started getting into the game. Much of the action remained at the pilot stage. But some projects showed that storage economics already make sense without subsidies, grants or other interventions -- in the right circumstances, of course.

    11. How the House Tax Bill Would Impact Wind, Solar, Electric Vehicles and Utilities

      How the House Tax Bill Would Impact Wind, Solar, Electric Vehicles and Utilities

      House Republicans unveiled a massive tax reform bill last week. While it wasn’t as damaging to renewables as many feared, the changes still pose a threat. Wind and electric vehicles stand to lose the most. Lawmakers are looking to slash tax credits for wind by more than a third and eliminate the $7,500 federal credit for electric-vehicle purchases. The Senate is crafting its own version of the bill, however, so many of the proposals in the House version may never become law.

      Can Puerto Rico Overcome a Colonial Past to Build a Greener Grid?

      On September 20, Hurricane Maria swept across Puerto Rico, destroying its electricity grid. The storm felled half of the cross-island transmission towers. Nine out of 10 back-alley power poles blew down. Every single customer on the island lost power. Amid the wreckage lies an opportunity for Puerto Rico to rebuild stronger and smarter. Tesla chief Elon Musk said his company power the island with solar and energy storage. “The Tesla team has done this for many smaller islands around the world, but there is no scalability limit, so it can be done for Puerto Rico too," he tweeted.

      Hurricanes Cause 'Apocalyptic' Devastation to Caribbean Power Grids

      Last Wednesday, Hurricane Maria passed over Puerto Rico, bringing 140-mile-per-hour winds, pelting rain and extreme flooding. After the storm moved on, Puerto Rico was left with "apocalyptic devastation" and absolutely no power. The island’s utility -- already bankrupt before the storm -- says it will be months before electricity is fully restored. The dire circumstances in Puerto Rico echo similar troubles now enveloping the Caribbean, where hundreds of thousands have been left with no electricity as Hurricanes Irma, Maria, and to some extent, Harvey, pummeled grids this past month, leaving entire islands without electricity.
