      A123 Awarded Production Contract by GM; Stock Rises
      GeneralMotors awarded a production contract to A123 Systems for batteries to be used in future GM electric vehicles to be sold in select global markets. The contract includes advanced Nanophosphate cells and fully integrated electronic components. The specific vehicles and brands will be announced at a later date. GM battery engineering teams have tested and validated the A123 battery chemistry at the automaker’s Global Battery Systems lab in Warren, Mich. Teams from both companies will now work on developing calibrations and software controls for the battery system in preparation for production.

    2. Analysis: Sunk costs of Hydro, Nuke, Coal, & Nat Gas Suppresses Renewables & Storage

      Analysis: Sunk costs of Hydro, Nuke, Coal, & Nat Gas Suppresses Renewables & Storage
      The increased cost comes from curtailment of renewable generation that occurs because thermal generators will choose to stay at a minimum level of operation even when uneconomic for them to do so at that specific time interval. That is to say the costs of turning off and turning back on are higher than the costs of operating below cost for a few hours. Because much of the electric grid is “inflexible”, this is an important area to consider for continued integration of renewables. Thus, this is one of the main reasons for consideration of storage technologies to reduce curtailment of wind and solar generation: renewables will be curtailed even before the total electrical demand becomes less than instantaneous renewable generation due to the inflexibility of the thermal power plants.

      Stocks: Is It Time to Buy Exide [and other battery cos.]?
      Companies like Advanced Battery (ABAT), A123 (AONE), Valence (VLNC) and Ener1 (HEV) have lost from 17% to 37% of their value in five days. But even conservative battery companies like Exide Technology (XIDE) and Johnson Controls (JCI), which make conventional lead acid products, have taken a huge hit. We have to ask, are people going to stop driving their cars when their batteries burn out? Are companies going to stop using their fork-lifts?...

      Report by IDC: 'Business Strategy: Distribution Optimization Coming in Waves'
      "Distributed renewable generation, energy storage, and electric vehicles increase network complexity, which will be adapted to, in part, through a redesign of the centralized command and control structure. Operators will need to shift from actively monitoring all distribution network activity to handling critical exceptions while relinquishing routine decision making to automated systems," said Marcus Torchia, IDC Energy Insights research manager, Intelligent Grid Strategies.

      Xcel Testing 20 x 50kW Batteries on Grid
      “It allowed us to sight the battery on property at a switching station, run cable to their substation, and provide us access to their voltage transformers to get our power on and off the grid,” Xcel said. The 20 50-kilowatt battery modules combined are the size of two semi trailers and weigh almost 80 tons. They are able to store more than 7 megawatt-hours of electricity, with a charge and discharge capacity of one megawatt.
