      California Gas Plant to Be Re-powered with Batteries + Solar

      The City of Glendale, California has released a plan to replace all but one of the plant’s existing generation facilities with a mix of battery storage, distributed solar and geothermal energy. Broken down by capacity, the plan calls for a 75 MW, 300 MWh battery energy storage system, up to 50 MW of distributed solar projects, energy efficiency and demand response programs. The plan also calls to keep the “peaker” portion of the former plant, which totals 93 MW of gas generation from up to five combustion turbines.

    2. How Energy Storage is Creating New Opportunities

      How Energy Storage is Creating New Opportunities

      A major disruption to the global economy is coming in the form of a seismic shift in energy markets. Largely driven by energy storage, this disruption will create exciting opportunities for the renewable energy market and will, in our view, drastically change the time of day electricity price curve (that is, the ‘duck curve’). The increased availability and adoption of battery storage will enable solar energy generators to match for the first time the supply of electricity to the time of customer use, which has historically been the major impediment to the growth of direct renewable electricity supply.

    3. Solar + Batteries Help the Grid Recover in Kaua'i

      Solar + Batteries Help the Grid Recover in Kaua'i

      On Sunday a cable failure took the largest power plant on the island of Kaua’i in Hawaii offline, which led to cascading failures in other oil-fired and hydro power plants, leading to a 2+ hour blackout for the island’s 66,000 residents. Despite work on the Port Allen oil-fired power plant continuing and still waiting on parts to repair the Kapaia oil-fired power plant which started it all, the Kaua’i Island Utility Cooperative (KIUC) did not have to implement further rolling blackouts on Tuesday. This was in part due to the contributions of solar and storage.

    9. Undersea Cable to Take Stored Solar from Australia to ASEAN Grid Backed by State Gov’t

      Undersea Cable to Take Stored Solar from Australia to ASEAN Grid Backed by State Gov’t

      Australian authorities have rallied behind what is arguably the largest solar-plus-storage project to be conceived in the world’s history: a scheme mixing 10GW of solar with 20-30GWh of energy storage. The developer intends to set up a 3,800 km high-voltage direct current submarine cable to transfer most of the installation’s output to Singapore, where it could cover 20% of power needs, while various reports also link it to the potential ASEAN grid. The plan, however, is to also link the mega-installation to Australia’s own electricity grid so that it can supply Northern Territory capital Darwin and others.

    11. Taking Aim at PJM’s 10-Hour Duration Capacity Rule for Energy Storage

      Taking Aim at PJM’s 10-Hour Duration Capacity Rule for Energy Storage

      The U.S. energy storage industry has been getting into arguments with grid operators over their plans to implement FERC Order 841, the mandate to integrate energy storage assets into the country’s wholesale energy markets. The biggest argument to date has been over PJM’s insistence on a 10-hour duration requirement for its capacity market. Last week, ESA and NRDC unveiled an analysis by Astrapé Consulting, using PJM data and industry-standard modeling, that indicates gigawatts' worth of energy storage in 2-hour, 4-hour and 6-hour durations could provide the same capacity value as power plants that run 24 hours a day.

      New study By Astrapé, Energy Storage Association, and National Resources Defense Council refutes PJM arguments in FERC 841 Order

      A new study released by Astrapé Consulting, funded by the U.S. Energy Storage Association (ESA) and National Resources Defense Council (NRDC), concludes that Federal Energy Regulatory Commission (FERC) efforts to encourage more energy storage deployment is supported by sound data. The findings, which are specific to the PJM market, show that PJM’s proposal requiring a storage asset to run for 10 continuous hours in order to qualify its full output for the capacity market is unnecessary and unduly restrictive. The Astrapé study concludes that a shorter storage duration requirement correctly reflects its capacity value for the foreseeable future.

      Minnesota to Consider Using Energy Storage for Peaker Plants

      Gas peaker plants may be among the first casualties of a new Minnesota law requiring utilities to include energy storage as part of their long-range plans. The provision, part of an omnibus jobs and energy bill, "puts energy storage on a level playing field with natural gas plants and other resources," said Ellen Anderson, executive director of the University of Minnesota's Energy Transition Lab. "Utilities will have to acknowledge the capabilities storage can provide as an alternative to, say, a fossil fuel plant."
