Including a variety of services in combination. In electricity, the supplier might combine generation, transmission, distribution, and related customer service and support functions. In natural gas it could include the bundling of exploration and production, transmission, distribution, generation. It also signifies providing a unit of gas to the customer at a price that includes the cost of gas and all associated transportation, balancing and storage costs
The acquisition of a specified quantity of generating capacity from another utility for a specified period of time. The utility selling the power/capacity in the infrastructure is obligated to make available to the buyer a specified quantity of power/capacity
In the natural gas sector, it is the capacity component in the transmission tariff for consumers of the transmission system.
An element in a two-part pricing method used in capacity transactions (energy charge is the other element). The capacity tariff is calculated based on the amount of capacity being purchased. Under the terms of the transportation agreement between INGL and natural gas consumers in Israel consumers have to pay the capacity charge whether they consume/transport the gas or not. To secure the finance for instance to build the Interconnector in the UK the original customers agreed to book all the then available capacity in the new system and signed up as IUK Shippers for a 20-year term. They agreed to pay a capacity charge throughout that period which provided a set rate of return on the capital investment required to deliver the project. Similarly, the subsequent projects to enhance the capacity of the Interconnector system have been funded on the basis of a capacity tariff paid over the remainder of the 20-year term (to the year 2018) and which provide a set rate of return. Capacity tariffs are paid monthly, whether or not gas is shipped, provided that the contracted capacity is made available for use (or is unavailable due to events such as planned maintenance).
The crystalline form of calcium carbonate and chief constituent of limestone and chalk.
Refers to the idea that emissions reductions anywhere within a specific area count toward compliance. For example, if a plant with multiple emissions sources is treated as being “under a emissions bubble”, regulators assess only the total emissions of the plant, not the emissions of each individual source, in determining compliance. Bubble also refers to an option in the Kyoto Protocol that allows a group of countries to meet their targets jointly by aggregating their total emissions. The member states of the European Union are utilizing this option.
