No. Procedure Time to Complete Associated Costs
1 Obtain discussion with Tepco on the actual construction date and effective date of contract

A discussion between the customer and TEPCO to decide on the actual construction date and the effective date of the contract takes place. The design team of the warehouse project will initially have a discussion with TEPCO regarding the project outline, construction period and basic requirements for power supply and connection.
Agency: Tepco 		1 calendar day no charge
2 Submit application at Tepco and await start of external connection works

Required documents for the application are single-line diagram, a lay-out of premise, harmonic calculation documents and application form. There is no external inspection. As there is no inspection of the internal wiring, TEPCO is asking the customer for the necessary information regarding the licensed electrician who did the internal wiring. Japanese laws require every owner/user to hire a licensed electrician to install the wiring. The information is submitted on the formatted application document and contains the name, license number and contact information of the electrician. There is no notarization needed for the documents, however the signature of the customer needs to be on the documents when applying online. The contractor building the warehouse will usually make an application for power supply and connection several months before the required date of the connection to allow TEPCO sufficient time to survey the proposed area in terms of electricity supply route and capacity required for the specific building. If the electricity main supply is not suitable, TEPCO will carry out necessary infrastructure work to provide the required utility services. There is usually no estimate prior to the determination of the actual contract start date. There is no connection fee: In case of overhead wiring, up to 1000 meters long, construction work does not require any financial responsibility by the customer.
