With the retail electricity market set to be deregulated in April, Tokyo Electric Power Co. on Thursday unveiled a range of new price plans that offer discounts to customers who sign up with specific partners.

The revamp, which involves third-party suppliers from the gas, communication and entertainment sectors, is an attempt to retain customers. Tepco has tens of millions of them, but from April many may desert it for cheaper competitors.

Tepco's new offers are designed to appeal to a wide range of users. Signing a package plan with both Tepco and Nippon Gas Co., a provider of household gas, will yield an annual discount of about ¥6,000.
