      TDX and Beacon Combine on Innovative Wind-Flywheel Energy Storage

      Beacon Power and TDX Power announced their partnership on the Saint Paul Island Flywheel Demonstration project. Located in the middle of the Bering Sea, this project will integrate Beacon Power’s flywheel energy storage system into TDX’s existing wind-diesel microgrid. Beacon’s technology will stabilize and support the grid and is expected to increase diesel-off time by an additional 10 to 15 percent.

      It’s Official: California Moves Grid Planning Toward the Edge

      On Thursday, the California Public Utilities Commission officially opened a proceeding that will set the ground rules for a multi-year transformation of distribution grid planning (PDF). It’s the first state in the country to take explicit steps to merge the traditional world of distribution grid planning -- centralized, one way and predicated on the past -- and replace it with a two-way, customer-engaged, networked grid model.

      PJM Interconnection Proposes New Generator Capacity Performance Rules to Provide Stronger Performance Incentives and Operational Availability During Peak Conditions

      On August 20, 2014, PJM Interconnection (PJM) proposed changes to their capacity market to address reliability concerns highlighted by generator performance during the 2013-2014 winter season, during which up to 22% of PJM capacity was unavailable due to cold-weather issues. The purpose of this proposal is to provide details regarding PJM’s proposed initial solution to issues identified in PJM’s August 1, 2014 whitepaper entitled “Problem Statement on PJM Capacity Performance Definition.” PJM expects the solutions detailed in this proposal will be adapted through discussions with stakeholders.

      The Next Next Thing for Distribution Grids? Distributed Energy Storage

      One of the first major smart grid systems that many utilities deployed was advanced meters. Unsurprisingly, utilities are trying to find new uses for their AMI systems to maximize return on these investments. AMI systems are well-suited for certain tasks—like supporting time-of-use rates and facilitating meter reading and customer billing. But AMI systems can’t solve the problem of providing advanced grid functionality. Indeed, it’s questionable how well AMI communication systems can even support sophisticated grid control applications like distribution automation. Taking an existing application and re-crafting it to be a grid-control enabler—ignoring the practicalities—is not the “next, next” thing, nor will it solve the biggest grid control problem that utilities face: rapidly growing use of distributed solar PV.

      The Next Big Challenge for Energy Storage

      The energy storage era is upon us. States like California and New York have adapted energy policies that will make it possible to economically deploy storage systems, while technology advancements have boosted performance and trimmed costs. For the first time in history it will become feasible to store electric energy. These breakthroughs in turn will change the underlying infrastructure of our whole industry. Utilities in most jurisdictions are legal monopolies because it was the only way to economically and technically bring electricity to a society. Forcing companies to build competing grid networks and power plants would have led to bankruptcies, chaos and terrible service.

      Distributed Marginal Price: The New Metric for the Grid Edge?

      The grid is changing from a one-way, centralized electricity delivery system to a distributed, networked system for generating, storing and consuming power -- and the technology is changing a lot faster than the economic and regulatory systems that govern it, as we've seen in states like California and New York that are struggling to catch up. But what if all this complexity could be boiled down to one metric that captures the costs, benefits and tradeoffs in a way that can serve the grid’s needs, not only on a minute-by-minute basis, but forecast over years to come?
