Supporting expansion of the use of decarbonized power sources to achieve carbon neutrality
Responsible for a wide range of tasks to expand the use of renewable energy
To expand the use of renewable energy, OCCTO provides the operation services for the Feed-in Tariff scheme (FIT scheme) that is a system to purchase renewable energy at a fixed price, and the Feed-in Premium scheme (FIP scheme) that is a system that grants a certain premium based on market prices.

FIT/FIP scheme
FIT is a scheme in which the national government guarantees that electric power companies will purchase electricity generated from renewable energy sources for a certain period of time at a fixed price. OCCTO provides services of calculating and determining the amount of subsidies based on the amount obtained by multiplying the procurement price by the amount of renewable energy electricity purchased and then deducting the avoidable cost (calculated from the market price) from it and granting subsidies to the respective electricity purchasing companies.
FIP is a scheme that provides support to ensure investment incentives while encouraging integration into the electricity market as a step toward the independence of renewable energy. OCCTO provides services of calculating and determining the amount of premiums based on the base price after subtracting the reference price (income expected from market transactions) by the amount of renewable energy power supply and granting premiums to the respective certified business operators.

Bidding system
This is a system in which procurement prices and base prices are determined by bidding to achieve both the maximum introduction of renewable energy and a reduction in the burden on the public. OCCTO provides bidding services (including conduct of bidding, determination of successful bidders, and management of participating bidders) under.

Reserve system for disposal costs of solar power generation facilities
This system requires certified business operators to maintain a reserve for disposal costs (basically, an external reserve in the form of withholding tax) to ensure a reliable accumulation of disposal costs by targeting all solar power generation projects of 10 kW or more that obtained a FIT/FIP certificate. OCCTO provides services of management and response to request for withdrawal of external reserves.
