      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.

    2. Energy Storage Safety Set to Move Forward in 2018 with New Fire Standards

      Energy Storage Safety Set to Move Forward in 2018 with New Fire Standards

      Most of the focus on energy storage safety has been on mobile applications, given the spate of exploding laptop and phone batteries. Lithium-ion batteries used in those applications are under tighter restrictions for size and density that can lead to higher risks. Stationary storage applications are often safer than mobile uses because there are not the same space constraints. But in some markets, space can also be an issue for stationary storage, especially with projects that use lithium-ion batteries.

      The IHS Markit Electric Resiliency Study – Much Less Than Meets the Eye

      In directing the Federal Energy Regulatory Commission (FERC) to consider a proposed rule that would subsidize Eastern merchant coal and nuclear generators, the Secretary of Energy points to a study by IHS Markit as justification for DOE's proposal. But that study, which claims to put a price tag on “just how important our current balance of coal, gas, nuclear and renewable energy really is,”1 has so many factual, logical and methodological flaws that it is wholly unsuitable to inform serious public policy.

      As Grid Modernization Accelerates, Which States are in the Lead, and Why?

      Grid modernization is not just a New York-California issue anymore. Committed and proposed expenditures are accelerating into the billions across the country, with no sign of a slowdown in sight. The grid's vulnerability to increasingly extreme weather and its consequences is apparent to everybody, and it must be strengthened, Centerpoint Energy CEO Scott Prochazka said. "Electricity is about 5% of GDP, but it is the first 5% because reliable energy supports every other aspect of the economy," he noted.

      An Inside Look at Using Energy Storage to Integrate Renewable Resources

      California is a leader in both renewable energy resources and energy storage. The state has one of the highest renewable portfolio standards in the U.S., mandating that 50% of all electric power be sourced from renewable resources by 2030, and the state has the first and some of the most robust incentives for energy storage. AB 2514 requires the state’s three investor owned utilities to procure 1.3 GW of energy storage by 2020, and AB 2868 requires each IOU to deploy an additional 166 MW of behind-the-meter and/or distribution tied storage.

      Choosing the Right Grid Infrastructure in the wake of the DOE Grid Study

      Since its release last week, the Department of Energy’s grid study has been under the harsh scrutiny of a broad range of industry players.The study was roundly criticized well in advance of its release by many stakeholders expecting it to unjustifiably blame renewable energy for the challenges facing the grid. Thankfully, the study that emerged last week has failed to live up to those fears. Instead, the report is generally fact-based and well-researched, and the key findings–that low natural gas prices and flagging load growth are primarily to blame for the economic crunch facing coal and nuclear power plants and that renewables pose no threat to our grid–are well-documented and well-understood by stakeholders ranging from the U.S. military to utility CEOs.
