Energy storage japan suspension notice

What are Japan's new battery energy storage regulations?

The government is also reforming its battery energy storage system (BESS) regulations, with batteries set to play an important role in maximizing renewable energy supply and avoiding grid constraints. We look at the changes being implemented and what they mean for renewable energy projects in Japan.

How long does it take for a power plant to be suspended?

The Electricity Business Act establishes a prior notification system for the suspension of power plants, which comes into effect within six month after promulgation. Large storage batteries will be regarded as a power generation business and provide with good the environment for connecting to the system.

How important is battery energy storage in Japan?

Battery energy storage systems (" BESS ") are playing an increasingly important role in the transition towards net zero. However, the regulations for BESS in Japan were generally perceived as requiring further clarification and development to promote this industry.

Why did Kishida call for stationary battery storage?

In August, Japanese prime minister Fumio Kishida called for an acceleration in the introduction of stationary battery storage along with a power grid expansion, to enable the planned increase in renewable capacity. BESS will provide an important source of backup power to support the higher share of intermittent generation.

Can energy storage projects take part in low-carbon capacity auctions?

Energy storage projects will be eligible to take part in low-carbon capacity auctions set to be launched this month in Japan.

Should battery storage be installed in Japan?

Installing battery storage would reduce the cost of upgrading the grid and avoid wasting clean generation. Most BESSs in Japan are currently co-located with renewable power installations, but the country is increasingly looking at installing standalone systems to provide grid balancing services.
