Glossary

  • A

    Asia premium

    The fact that gas prices in Asia are higher than in other regions. The reason for this is believed to be that sellers take advantage of buyers because it is difficult to secure alternative energy sources to crude oil and natural gas in East Asia, including Japan.

  • C

    CBM

    CBM (Coal Bed Methane) emerges during the coal formation process. It is methane stored near underground coal beds. It has been extracted from some coal areas in recent years.

    City gas

    Generally gas supplied and sold over broad areas from gas holders and extraction bases. The gas sold by Tokyo Gas is also categorized as city gas.

    Cogeneration

    Systems which supply electric power using gas engines, gas turbines and fuel cells and effectively utilize the heat created in that process for steam, air conditioning, hot water supply, etc.

    Combined cycle

    A power generation format mostly combining gas turbines with steam turbines. In addition to the power generation by the gas turbine, the waste heat during generation is recovered to boil water to generate electric power using a steam turbine, with the dual generation realizing high thermal efficiency.

    Cove point project

    A shale gas export project in the state of Maryland in the U.S. This is our company’s first shale gas project, with shipments scheduled to begin from fiscal 2017.

    Crude-oil linked LNG pricing

    The price of most LNG imported into Japan is linked to the price of crude oil.

  • D

    Distributed energy systems

    Small-scale power generation nearby demand locations. The energy efficiency is high because the heat created during power generation can be used as steam or hot water. Gas cogeneration systems and the ENE-FARM residential fuel cell system are also examples.

  • E

    ENE-FARM

    A residential-use fuel cell system which causes a reaction between oxygen and the hydrogen in gas to generate electric power and also effectively uses the heat created in that process.

    Energy solutions

    The proposal and provision of solutions to various customer issues including using energy effectively and reducing energy costs.

  • F

    Floating LNG

    Floating production facilities that will refine, liquefy, store and transfer natural gas at sea. Since production facilities normally built on land will be constructed on the sea, floating LNG has the advantage of reducing the costs of pipeline construction, and will make the development of medium and small gas fields that were previously unprofitable worthwhile. Commercialization has been advancing in recent years along with technology development.

    Fuel conversion

    Having users presently utilizing fuel oil or other energy sources change over to city gas. Tokyo Gas promotes fuel conversion to increase our industrial use gas sales volume.

  • G

    Gas mutual exchange system

    A system connecting Tokyo Gas pipelines with other companies’ pipelines which enables mutual gas supply during disasters and other emergencies.

    Gas rate adjustment system

    A system which adjusts unit gas rates (price per m3) each month in reaction to fluctuations in LNG (Liquefied Natural Gas) and LPG (Liquefied Petroleum Gas) fuel costs from changes in crude oil prices and foreign exchange rates. Under this system, changes in fuel procurement costs basically have a neutral effect on the profits of gas utilities.

  • H

    HEMS

    HEMS (Home Energy Management System) is a system using telecommunications technologies to make home energy use visible and manage it appropriately.

    Henry Hub

    Henry Hub is the name of a natural gas distribution hub in the state of Louisiana in the southern U.S. The price of natural gas bought and sold here is used as a pricing point for the NYMEX (New York Mercantile Exchange) futures price index so it is also the representative U.S. natural gas price index.

  • L

    LNG (Liquefied Natural Gas)

    The main component of city gas. Natural gas cooled to a temperature of around minus 162℃ and liquefied. Because the volume is reduced to 1/600 through liquefaction, it is suitable for transportation by tankers.

    LNG terminal

    Plants for the regasification of LNG transported by tankers and the production of city gas. Tokyo gas presently has three LNG terminals at Negishi, Sodegaura and Ohgishima, and construction of the Hitachi LNG terminal is underway.

    LNG value chain

    This refers to generating the maximum value added from unified business development running from natural gas resource development through procurement and transport to production and further to customer sales and service. Tokyo Gas is engaged in LNG businesses from upstream through downstream based on this concept of the LNG value chain.

    Long-term contracts

    Contracts concluded with LNG sellers for the sales and purchase of LNG over a long term (around 10-20 years).

    LPG

    Liquefied Petroleum Gas. Propane and butane are the main components. High-calorie LPG is added to LNG to maintain a fixed level of calories in city gas.

  • M

    Methane hydrate

    An ice-like substance in which methane is trapped inside water molecules. When methane hydrate is broken down, methane is generated. There are estimated to be substantial reserves on the seabed nearby Japan, which are expected to become a new domestic energy resource.

  • N

    Natural gas

    A type of fossil fuel like oil and coal. A flammable gas whose main component is methane (CH4). It contains no carbon monoxide and is lighter than air. Natural gas is safer compared with gases whose main component is propane.

  • P

    Power generation use

    One of the use applications of gas. This refers to gas used as fuel at natural gas fired thermal power plants.

  • R

    Renewable energies

    Photovoltaic, solar thermal energy, hydroelectricity, wind power, biomass, geothermal energy and other energy sources that can be renewed relatively quickly after they are used. Because resources are not depleted, these are attracting attention as comparatively clean energy sources in place of oil, etc.

  • S

    Shale gas

    Natural gas stored in shale. Shale gas was difficult to extract in the past, but its production volume has been increasing with recent technological innovations.

    Slide time lag

    The time lag under the gas rate adjustment system between the payment of fuel costs and their reflection in gas rates. When fuel costs rise, for example, this has a negative effect on profits because while the fuel expenses which our company pays increase, they cannot immediately be passed on to gas rates. The time lag in the impact on current term profits may be as long as five months, but over the long term the effects are considered neutral.

    Smart energy networks

    Network systems that link energy systems comprising cogeneration and renewable energies among multiple users that can mutually exchange heat and electricity, and utilize information technology to realize optimal heat and electricity supply and demand toward energy conservation and CO2 emissions reductions.

    Smart meters

    Gas and electricity meters with communications functions. In addition to reducing meter-reading costs, they are also expected to contribute to coordination of supply and demand since they enable the mutual transmission of data between utilities and customers.

    Spot trading

    LNG spot trading is short-term trading of one year or less.

  • T

    Total payout ratio

    One index of return to shareholders calculated as the total return to shareholders, that is the sum of dividends plus treasury stock purchases, divided by net profits. Tokyo Gas has announced that the company will maintain a total payout ratio of around 60% through 2020.

    Truck (Lorry) distribution system

    A system for the supply of gas using trucks as LNG in trucks. This makes it possible to use gas in areas which do not have gas pipelines.
