        JEA Shakes Up Solar Policies

        JEA unanimously approved Tuesday policies to increase the authority's reliance on solar energy, to cut an incentive for homeowners to install solar panels and to create an incentive for homeowners to add storage batteries to their solar arrays. JEA will add up to 250 megawatts of solar power to its energy portfolio. It is budgeting up to $50 million to buy land for solar farms, which could be operational by late 2019. This addition of solar power, which dwarfs the 50 megawatts currently produced by JEA, would make Jacksonville the largest solar community in the United States per capita, based on projections of other cities' portfolios.

        Electric Resilience: Why We Need to Quantify its Value

        Power outages are a nuisance to some, an economic burden to others, and even lethal in some cases. Because the pain that outages inflict varies so much, it is hard to place a universal price on electric resilience. So it is crucial that each customer knows what power loss costs them as they weigh their need for a microgrid, according to Michael Bakas, senior vice president of Massachusetts-based Ameresco.

      5. Nuts and Bolts of Financing Storage

        Nuts and Bolts of Financing Storage

        The next big challenge for energy storage, after bringing down the cost so that storage is economic and finding a suitable business model, is financing. There are two ways to look at project finance. One is that borrowing a large amount of money to build a project requires locking down costs and locking in a revenue stream so that the bank can determine how much money the sponsor will have to pay debt service. Traditional project finance involves borrowing to build a project on a “nonrecourse” basis: the lender looks to the project company that owns the project rather than the ultimate owners for repayment. Therefore, it is keenly interested in the certainty of the revenue stream and the predictability of costs. It focuses on the net amount the project company will have to pay debt service after covering costs. This allows it to calculate a debt-service-coverage ratio. That, in turn, determines how much can be borrowed. For example, if the lender requires a debt-service-coverage ratio of 1.4x, then the net revenue stream each payment period must be at least 1.4 times the required interest and principal payments on the debt.

        Tesla Starts Shipping Powerpacks to Puerto Rico

        Elon Musk said last week that Tesla would accelerate its effort to help bring power back to Puerto Rico after sending a few hundred Powerwall battery packs to the island where the electric grid was destroyed by hurricanes last month. Now we learn that Tesla is indeed stepping it up with now a new shipment of Powerpacks. A single Powerpack 2 battery pack has the same energy capacity (210 kWh) as almost 16 Powerwall 2 battery packs combined (each 13.5 kWh).

        It’s been a tough year for North American electric grids — hurricanes, heat, fires, an eclipse. But an Arizona utility is reporting that it did just fine with some help from new microgrids and energy storage. “Driving past a microgrid or energy storage unit, many customers wouldn’t look twice, but those technologies are playing an increasingly important role in delivering efficient energy on the hottest days of the year,” said Jacob Tetlow, vice president of transmission and distribution operations at Arizona Public Service (APS), which serves about 2.7 million people

        Policy Biggest Obstacle for Storage, Panel Says

        SAN DIEGO — The electricity sector continues to identify possible applications for energy storage while costs for the technology steadily decline, but the lack of cohesive federal, state and local policy remains the chief obstacle to integration, a panel of experts said Wednesday. “The technology piece has caught up. What we cannot afford to do is let the policy drag it down,” Kiran Kumaraswamy of AES Energy Storage said during a panel discussion at the Infocast Transmission Summit West. Industry and policymakers can develop a framework for adopting storage once they determine the magnitude and type of need for the technology, he said.

        On Tuesday, October 4, the U.S. Senate Committee on Energy and Natural Resources held a full committee hearing to discuss the status and future of energy storage technologies. Committee Chairman Sen. Lisa Murkowski (R-AL) opened the hearing discussing the recent massive power outages caused by hurricanes in Puerto Rico, the U.S. Virgin Islands, Texas, and Florida. In the wake of these disasters, she emphasized consideration of energy storage technologies as part of grid reliability and resilience in rebuilding programs. Sen. Al Franken (D-MN) urged that a supplemental aid package assisting Puerto Rico and the Virgin Islands should be a bipartisan effort aimed at rebuilding grid infrastructure in a renewable and sustainable way, with energy storage technologies an important part of the solution.

        Puerto Rico Could Show the Future of Solar and Energy Storage

        lon Musk has gotten a lot of attention for his proposed efforts to rebuild Puerto Rico's electric grid, which could prove how cheap and valuable solar and energy storage could be in the decades ahead. Musk's plan isn't public yet, but it would likely mean bringing Powerpacks to the island to help deal with outages that still affect 90% of consumers. And this may be an instance where Tesla (NASDAQ:TSLA) could build a solution faster than most utilities. But Tesla isn't the only company eyeing solutions in Puerto Rico. Sonnen has said it will build microgrids on the island as well. This is potentially the first big test for solar plus storage as a fast solution to island infrastructure challenges.

        Grid Resiliency is a Problem, But Stockpiling Coal isn’t the Answer

         According to Mark Dyson, an expert who studies grid resilience as part of the Rocky Mountain Institute’s Electricity Innovation Lab, the U.S. does face a problem with grid resiliency. Look no further than the mainstream news headlines about Puerto Rico’s lack of electricity to see the problem in living color. However, the U.S. Department of Energy’s recently proposed rulemaking, which directs FERC to “properly value” coal and nuclear power plants for their ability to be “resilient” by having a 90-day pile of fuel onsite, totally misunderstands the problem. Check out Dyson’s comments about how to address the real problem of grid resiliency below.

        Hawaiian Electric Takes First Steps to Utility-Scale Commercial Energy Storage

        Hawaiian Electric Co. (HECO) has big plans for energy storage, but is wary of moving too quickly. The utility is looking for better storage technology and economics before moving too much on deployment. The island state is often considered a test case or laboratory for the integration of renewable energy. With a 100% renewable portfolio standard in Hawaii and a 2045 target date, the state’s main utility is quite focused on what its generation mix is going to be and how it is going to get there.

        National Grid Measures Real-Time System Inertia for the First Time

        Until now, grid operators used estimates to measure grid stability, otherwise known as system inertia, leaving measurements suspect to margin errors. These estimates were also used to set multi-year budgets for grid infrastructure investments, energy reserve services and dictated the trading outlooks between renewable and fossil fuel energy being used by the grid. However, Project SIM has enabled the National Grid to gain real-time visibility of inertia on its systems, which are becoming increasing volatile as intermittent renewables generation claims a greater share of the UK’s energy mix.
