      Utah county notifies FERC of opposition to pumped storage plan

      The County Council voted unanimously to send a letter of concern to the Federal Energy Regulatory Commission regarding a proposed hydroelectric storage facility in Long Canyon, Utah.  Utah Independent Power filed a preliminary permit Jan. 12 to perform feasibility studies for the Long Canyon Pumped Storage Project. The deadline for filing comments regarding the application is May 22.

    2. Ontario's largest pumped hydro project proposed - height of four Niagra Falls

      Ontario's largest pumped hydro project proposed - height of four Niagra Falls

      The project will use an abandoned deep open pit iron mine.  A reservoir  above the pit will be constructed using nearby waste rock. When the cost of electricity is lower, water in the pit will be raised to the reservoir. In daytime, water from the reservoir can fall the distance of four Niagaras to run the generator deep in the pit.

    3. LightSail's Compressed Air Grid Storage Explanation (good overview)

      LightSail's Compressed Air Grid Storage Explanation (good overview)

      To make CAES more efficient, the LightSail system captures and stores both the mechanical energy and the thermal energy used in compressing air.  To do this, a water mist is infused into the compression chamber as the air is compressed. Water can hold 3,300 times as much heat as the same volume of air, and is able to capture the heat generated by the process more effectively.  Both potential energy in the form of pressurized air and the heated water can be stored.

    6. Analysis: Is Sodium Sulfur (NaS) a viable Grid Storage Solution?

      Analysis: Is Sodium Sulfur (NaS) a viable Grid Storage Solution?
      In September 2011, sodium-sulfur (NaS) batteries at a Mitsubishi Materials Plant in Japan, caught on fire. It took firefighters more than 8 hours to control the blaze, and two weeks to extinguish the fire. NGK Insulators, the company that manufactured the storage system, does not know the cause of the fire, has suspended production of its NaS cells, and advised customers to refrain from using their batteries.

    7. German offshore wind developer looks to Norway pumped hydro storage

      German offshore wind developer looks to Norway pumped hydro storage

      !f wind reaches 20-25% of electricity supply capacity, it could be meeting 100% of demand during off-peak times, making storage essential. “You need the Norwegians for that [for their pumped-hydro capacity]. … we have them on board, as Statoil, Statkraft are the partners of RWE on this project.” [said Vahrenholt of RWE Innogy]

    8. $15B Wind & Pumped Hydro Projects in Lesotho

      $15B Wind & Pumped Hydro Projects in Lesotho

      Contractor Harrison & White (Johannesburg) unveiled the Lesotho Highlands Power Project, to be comprised of 6GW of wind and 4GW of pumped hydro over the next 15 years. The projects will be built and equity provided by Harrison & White and the Lesotho government, while debt will come from several undisclosed Chinese financial institutions. The first project will be a 150MW wind farm that is slated to enter construction next year.
