Please note that electricity contracts are based on annual contracts, so we cannot accept any further changes to the amperage for one year after the amperage change.
Please sign a contract with the number of amperes that will be used the most during the year. Also, if you would like to increase the ampere, depending on the equipment, we may not be able to accommodate your request. We appreciate your understanding in advance.
