The Problem

Wind and solar are becoming a big part of the future of clean renewable energy for California, the United States and the world.  With California renewable procurement on a trajectory to exceed 33% by 2020 and 50% by 2030, new system challenges to reliably operating the electric grid will be introduced.


Intermittency and load curve swings can be exacerbated by the mix of renewables while current load patterns will not be able to absorb the night time wind renewable generation and morning solar ramp, leading to over generation and renewable curtailment.  Building a portfolio of energy storage and load shifting options can help smooth out these load swings and intermittency issues while maximizing the current investment in generation, transmission and distribution infrastructure.


Unfortunately the costs associated with traditional grid level battery energy storage and load shifting technologies are very expensive, difficult to site in populated areas and require significant distribution and transmission interconnections to meet these reliability and management challenges. The lack of large-scale production and mature mechanisms for energy storage in the electricity markets further adds to the high cost of available technologies, until now.


Our Technology

The Cold Battery can repeatedly and consistently shift 16,500 MWh of load each day in California alone.  To do this using conventional grid battery storage would cost approximately $16.5 billion dollars using a conservative estimate of $1000 per KWh.  With the Cold Battery it would cost approximately $200 million.  Implementation may consist of retrofits, modifying existing consumer and commercial product designs or a combination of both with the patent pending technology.


Below is the projected comparison to traditional grid connected battery energy storage systems (BESS) such as sodium-sulfer (NaS) and pre-commercial lab Cold Battery results.

  • Enables time-shift of energy delivery to facilitate balancing of electricity supply and load at reduced cost;
  • Helps smooth out steep capacity ramps and peak loads to better integrate renewable generation;
  • Allows consumers to save money by shifting use outside of Time Of Use rates;
  • Supply demonstrable capacity credit to Independently Owned Utilities (IOU’s) that help delay investments in generating capacity;
  • Better utilization of existing transmission and distribution infrastructure to delay capacity investments;
  • Reduces rate increases for customers because of the delayed investments;
  • Allows reliable and more integration of renewable generation into the grid to help meet and exceed mandates like California’s AB 32 and SB 350; and
  • Reduces the need for expensive gas generation plants to satisfy peak demand and reduces corresponding greenhous gas emmissions.


As California implements solutions to reliably manage renewable generation, the rest of the world is watching and waiting to adopt.  Initial Cold Battery test data shows it will be the most economically disruptive storage and peak load shifting technology.  It is driven by the mutual vision of the founders and investors to put in place energy storage and load shifting technologies, working with manufacturers and the IOU’s to help meet California and the world’s future energy needs, while making a substantial profit for our early investors.
