    1. Report by Pike: “Energy Storage on the Grid”

      Report by Pike: “Energy Storage on the Grid”
      Pike Research anticipates that among the various application segments in this market, the integration of renewable energy – primarily wind power – will represent approximately 50% of the total capacity deployed for long duration energy storage. The firm forecasts that load leveling/peak shifting will represent 31% of the total market, followed by arbitrage (12%) and T&D upgrade deferral (7%).

    2. Opinion: The Missing Strategy for Storage

      Opinion: The Missing Strategy for Storage
      The reason that electricity is not stored in large quantities on the U.S. electricity grid today (other than 21.5 gigawatts of pumped storage hydropower) is because it is still generally less expensive to generate an electron than to store it. What is the case for government investment (either directly or through tax credits) in grid-connected energy storage technology? Why can’t the government leave development of grid-connected energy storage to the private sector alone?

    3. SDG&E & SolarGen2 Sign 25yr, 150MW Power Purchase Agreement

      SDG&E & SolarGen2 Sign 25yr, 150MW Power Purchase Agreement
      Solar Gen 2, a private solar development firm, signed a 25-year, 150-megawatt (MW) power purchase agreement (PPA) with San Diego Gas & Electric (SDG&E), a subsidiary of Sempra Energy. The photovoltaic solar project consists of three separate 50-MW sites where construction should begin during the first quarter of 2012 and expects to be completed by the third quarter of 2012. The Solar Project is located on private, fallowed land in the Imperial County, California.

    5. Grid-Scale Thermal Energy Storage Prospects

      Grid-Scale Thermal Energy Storage Prospects
      Future thermal energy storage will cover the temperature range from sub-freezing to 1000°C. Heat-of-fusion technologies offer greatly extended useful service lives and cost-competitive long-term costs. Most thermal energy storage systems will be built on a large scale that involve massive volume. Most future research may involve high-temperature systems that generate steam and energize air turbine engines.

    7. Renewables Boom Could Strain Germany's Grid

      Renewables Boom Could Strain Germany's Grid
      Dena energy agency director, Stephan Kohler, said: "My demands for the new renewable energy laws would be that additional capacity is to be built only where there is an existing network infrastructure … Another prerequisite would be that it must be possible to absorb the new capacity through demand side management or integrate it in storage systems at a European level".

    8. Google Study: "Clean Energy Innovation" - Storage

      Google Study: "Clean Energy Innovation" - Storage
      Storage helps integrate intermittent renewables like wind and solar, shape demand, and prevent service interruptions. Two basic types of breakthroughs in grid-storage were modeled: short duration storage capable of discharging loads for less than 1 hour; and larger scale storage capable of discharging for over 1 hour. We then modeled five business cases for storage: 1) Frequency Regulation; 2) Load Following; 3) Price Arbitraging; 4) Capacity Deferment; and 5) Grid Reliability. State and federal policies remained the same as BAU.

    9. Opinion: The Alternative Energy Fallacy

      Opinion: The Alternative Energy Fallacy
      The basic premise of alternative energy is that widespread deployments of wind turbines, solar panels and electric vehicles will slash hydrocarbon consumption, reduce CO2 emissions and give us a cleaner, greener and healthier planet. That premise, however, is fatally flawed because our planet cannot produce enough non-ferrous industrial metals to make a meaningful difference and the prices of those metals are even more volatile than the prices of the hydrocarbons that alternative energy hopes to supplant.

    11. Bright Energy's Underwater CAES 'Bag'

      Bright Energy's Underwater CAES 'Bag'
      Bright Energy's core technology is a long, flexible polymer/glass bag shaped like a giant sea cucumber. One end of the bag is attached to an air hose on the surface. A self-standing system with its own generator could produce power for under 6 cents a kilowatt hour, the CTO said. If you could latch onto a generator at an offshore wind farm, the costs could potentially drop to 2.5 cents.

    12. Little State Money for Utility Upgrades

      Little State Money for Utility Upgrades
      Tight budgets affect electric utilities that need to find their own financing to pay for upgrades. It's a complicated process that in many states requires approval of the public utility commission for any rate increases. One Senate proposal would use $10 billion in federal seed money to establish an independent bank that gives out loans and loan guarantees to major infrastructure projects.
