Ensuring Stable Supply of Energy in Japan and Abroad

Development of the Electric Power Business

The Tokyo Gas Group is developing its electric power business in the belief that a stable and affordable supply of energy is a vital public expectation, as demand for natural gas has been rising and the domestic environment surrounding energy has been undergoing major changes since the Great East Japan Earthquake.

Expansion of Competitive Power Sources

Building an Optimal Portfolio of Power Sources

Tokyo Gas recognizes that it is more important now than ever before to provide a stable source of electricity, taking into account major changes in the energy-related environment such as power and gas system reforms, and growth in our sales stock. The stable acquisition of power sources is therefore necessary, and we are establishing an optimal power source portfolio that combines our own power source with power purchased from other companies.

Securing Additional Power Sources

We are promoting the construction of natural gas-fueled power stations and are committed to ensuring stable supply in the following ways. First, we will construct power stations close to areas of demand. Second, we will use highly efficient combined cycle power equipment to reduce environmental impact. And third, we will locate power stations near our LNG terminals to benefit synergies and enable efficient and stable management.
With the commencement of the commercial operation of the Ohgishima Power Station’s Unit 3 in 2016, the composition of the Tokyo Gas Group’s power sources are:
  • Tokyo Gas Baypower Co., Ltd. (a wholly owned subsidiary with a total output of about 100,000 kW),
  • Tokyo Gas Yokosuka Power Company, Ltd. (a 75% owned unit with 240,000 kW),
  • Kawasaki Natural Gas Power Generation Co., Ltd. (a 49% owned unit with 840,000 kW), and
  • Ohgishima Power Company, Ltd. (a 75% owned unit with 1.22 million kW)
In addition, we have decided to receive the entire output of about 1.20 million kW of the Moka Power Station, which Kobelco Power Moka Inc. is building in Moka, Tochigi Prefecture, with supply to start in 2019. As a result, we will establish a system for stable electricity supply by expanding our own power source capacity from the current level of about 1.6 million kW to 3 million kW in 2020.
Anticipating future system design requirements and the market environment, we will continue to establish an optimal portfolio to secure a power source capable of generating electricity at the scale of 5 million kW in the 2020s.

Stable Power Generation

The Group’s thermal power stations are fueled by natural gas produced at our LNG terminals. The stations maintain a stable supply of electricity through their operational and control activities as well as daily checks and periodic inspections. Capitalizing on expertise acquired in the gas service business, we will do our best to ensure safety and stable supply while addressing environmental concerns and also supply electricity at lower cost in our efforts to meet social demand and expectations as a total energy business company.
