NAS
Sodium Sulfur Battery ENERGY STORAGE SYSTEM

Los Alamos, NM, USA

NAS used for Smart Grid

Location

Japan-U.S. Collaborative Smart Grid Project at New Mexico deploying NAS

Owner Los Alamos County
System Size 1MW
Commissioning Operation Date September, 2012

Background

  • Japan-U.S. Collaborative Smart Grid Project was carried out jointly by New Energy and Industrial Technology Development Organization (NEDO), State of New Mexico government, Los Alamos National Laboratory, Sandia National Laboratories, Japanese participants including NGK, and other participants. Upon the demonstration project completed, the system has been transferred from NEDO to Los Alamos County in March, 2014 and it's kept in operation.
  • A smart grid with a high rate of photovoltaic power introduction was constructed in Los Alamos, New Mexico.
  • A power source to adjust electricity supply and demand with absorbing power fluctuation of photovoltaic is required.

Solution

  • NAS and lead acid battery are connected to the grid and controlled to stabilize the grid.
  • NAS addresses photovoltaic power fluctuations with its quick response.
  • Utilizing its large energy capacity, NAS stored the energy from photovoltaic and delivered it to the grid when the power demand is high.

Additional Benefits

  • The power balancing capability realizes strategic energy trade considering price change in wholesale market.
