Secure Short-term to Mid - to Long - term Stable Supply

In addition to aggregating electricity supply plans that are annually submitted from all electricity companies, OCCTO formulates Cross-regional Network Long-term Policy and Development Plans to secure not only short-term but also mid- to long-term stable supply on a nationwide scale.

Electricity supply plans will be consolidated, and a stable supply of electricity will be secured for the short, medium, and long terms.

The electricity supply plans are plans in which the 10-year supply-demand forecast, development of power stations and development of transmission/distribution g rids are aggregated. All electricity companies have an obligation to submit a supply plan to the Minister of Economy, Trade and Industry in accordance with the Electricity Business Act. OCCTO grasps and evaluates centrally the supply-demand balance nationwide and in supply areas for short-, mid-, and long-term by aggregating these plans. Furthermore, OCCTO secures a s table supply by generator procurement called “Generation Plant Bidding “ when necessary.

Contribute to efficiency improvement and activation of electricity market

As electrical power production became separated from power distribution and transmission in 2020 and as renewable energy is increasingly adopted, OCCTO has been investigating, undertaking a detailed design of, and operating new markets in which the value of electric power is traded in order to develop a framework for securing and harnessing the supply and balancing capacity required for the stable supply of electricity on a medium- to long-term basis at the lowest possible cost.

Studying, undertaking a detailed design of, and operating the capacity market

The full liberalization of the electricity industry and large-scale adoption of renewable energy threatens to lower the predictability of returns on investments in power sources. The resulting shortfall in investments in power sources could lead to power shortages in the future. The capacity market will increase the predictability of returns on investments in power sources by paying some of the costs required for power sources in accordance with the value of the capability of power sources to generate electricity (supply capacity), which in turn will help secure supply capacity and adjustment capacity on a medium- to long-term basis. OCCTO is investigating, undertaking a detailed design of, and operating the capacity market as a market manager.

Studying and undertaking a detailed design of a balancing market

As renewable energy becomes the primary power source, it will be possible to more efficiently procure and operate the balancing capacity that is needed to allow general transmission and distribution operators to provide a stable supply of electricity by realizing cross-regional procurement cross-regional operations in a balancing market. OCCTO is studying and undertaking a detailed design of this market.

Formulate Long-term Policy and Development Plan for cross-regional network, and take initiative in reinforcing required facilities

OCCTO formulated a long-term policy (Long-Term Policy on Cross-regional Network), which put together a course of action related to the development and upgrading of cross-regional interconnection systems nationwide and announced this policy in March 2017. In addition, OCCTO formulated and announced a cross-regional network development plan pertaining to interconnection facilities linking Tokyo and Chubu in June 2016. In order to fulfill one of its new roles, which was added under the Act for Establishing Energy Supply Resilience and which entails formulating Cross-regional Network Development Plans and submitting them to the Government, OCCTO has accomplished formulating and publishing a cross-regional network development plan pertaining to interconnection facilities linking Hokkaido and Honshu, and revision and publish of a cross-regional network development plan pertaining to interconnection lines linking the Tohoku region and Tokyo. OCCTO has submitted the above two plans to the Minister of Economy, Trade and Industry.
