Hitachi developing packaged 1 MW Li-ion energy storage system for grid stabilization

Hitachi, Ltd. has developed a container-type energy storage system as a core energy product for ensuring the stable use of distributed renewable energy such as wind and solar power, while maintaining the power supply-demand balance. The energy storage system, which packages a 1 MW Li-ion battery system with power electronics and control technologies, fuses Hitachi’s electricity grid control technologies built up in the Hitachi Group and Hitachi Chemical Co., Ltd.’s battery-related expertise.

In the beginning of 2014, Hitachi plans to begin a demonstration test of this energy storage system in North America. Plans call for Hitachi to reflect the results of this testing in a commercial product after verifying the commercial viability and performance of the system in the electricity trading market connected with maintaining the electricity supply-demand balance. Furthermore, Hitachi will examine whether to promote the system, to be named “CrystEna” (Crystal+Energy), as one of its solution businesses for expanding the transmission & distribution business in the global market.

Demand for energy storage systems is anticipated to grow rapidly because such systems can help maintain the electricity supply-demand balance, effectively utilize energy, and stabilize power quality, especially with the increasing integration of intermittent renewable power generation. The European and North American markets, which are leading the way in electricity deregulation, in particular are expected to see a further increase in the use of distributed renewable energy, spurred by the materialization of plans to construct transmission networks that will transmit power generated from renewable energies to major cities, and by the introduction of subsidies such as tax credit and feed-in tariff (FIT) schemes.

The necessity for energy storage systems is thus rising for maintaining the supply-demand balance, power frequencies and voltages, securing backup power, and eliminating the impact on grid operations.

The Hitachi Group has been involved in the energy storage business over several decades. It has leveraged Hitachi Group technologies and expertise in a wide range of fields including: electricity generation, transmission and distribution to grid stabilization to develop everything from facilities to manufacture batteries to systems for providing materials, batteries, power conditioning systems (PCS), control systems and other systems under one roof.



"1 megawatt", but nothing to say whether this system is good for megawatt-seconds, megawatt-hours or megawatt-days.  It's as if this is to be sold to rubes, not grid managers.


Power: 1MW

Ontario, Canada has come out with a 20-year energy generation plan to:

1. reduce nuclear from 56% to 42% due to high repair and overhaul cost of existing Candu Nuclear plants and extreme high cost of new nuclear power plants..

2. offer lower cost energy to customers who have agreed to let their electricity supplier remotely turn off their A/C units, hot water heaters, heating, and other major appliances during peak demand hours.

3. impose an immediate 11% tariff increase and 33% over the next 3 years. (probably at the persistent demand of local ICEVs manufacturers '100% in Ontario**' and Oilcos to block the arrival of more HEVs, PHEVs, BEVs and FCEVs?)

4. start closing old nuclear plants and replacing them with wind farms and NG power plants.

5. convert more coal fired power plants to NG.

** Almost 100% of all ICEVs manufacturing in Canada is done in Ontario but no HEVs, PHEVs, BEVs or FCEVs are produced in Ontario.
