In economic terms, electricity is a commodity capable of being bought, sold, and traded. An electricity market, also power exchange or PX, is a system enabling purchases, through bids to buy; sales, through offers to sell; and short-term trading, generally in the form of financial or obligation swaps. Bids and offers use supply and demand principles to set the price. Long-term trades are contracts similar to power purchase agreements and generally considered private bi-lateral transactions between counterparties.
The electric power industry covers the generation, transmission, distribution and sale of electric power to the general public and industry. The commercial distribution of electric power started in 1882 when electricity was produced for electric lighting. In the 1880s and 1890s, growing economic and safety concerns lead to the regulation of the industry. What was once an expensive novelty limited to the most densely populated areas, reliable and economical electric power has become an essential aspect for normal operation of all elements of developed economies.
Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. Another advantage is that billing can be based on near real-time consumption rather than on estimates based on past or predicted consumption. This timely information coupled with analysis can help both utility providers and customers better control the use and production of electric energy, gas usage, or water consumption.
Water supply is the provision of water by public utilities, commercial organisations, community endeavors or by individuals, usually via a system of pumps and pipes. Aspects of service quality include: Continuity of supply, water quality and water pressure. The institutional responsibility for water supply is arranged differently in different countries and regions. It usually includes issues surrounding policy and regulation, service provision and standardization.
The Ontario Energy Board regulates natural gas and electricity utilities in the province of Ontario, Canada. This includes setting rates, and licensing all participants in the electricity sector including the Independent Electricity System Operator (IESO), generators, transmitters, distributors, wholesalers and electricity retailers, as well as natural gas marketers who sell to low volume customers.
Municipalization is the transfer of private entities, assets, service providers, or corporations to public ownership by a municipality, including a city, county, or public utility district ownership. The transfer may be from private ownership or from other levels of government. It is the opposite of privatization and is different from nationalization. The term municipalization largely refers to the transfer of ownership of utilities from Investor Owned Utilities (IOUs) to public ownership, and operation, by local government whether that be at the city, county or state level. While this is most often applied to electricity it can also refer to solar energy, water, sewer, trash, natural gas or other services.
The Public Utility Regulatory Policies Act is a United States Act passed as part of the National Energy Act. It was meant to promote energy conservation and promote greater use of domestic energy and renewable energy. The law was created in response to the 1973 energy crisis, and one year in advance of a second energy crisis.
A smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor. Smart meters communicate the information to the consumer for greater clarity of consumption behavior, and electricity suppliers for system monitoring and customer billing. Smart meters typically record energy near real-time, and report regularly, short intervals throughout the day. Smart meters enable two-way communication between the meter and the central system. Such an advanced metering infrastructure (AMI) differs from automatic meter reading (AMR) in that it enables two-way communication between the meter and the supplier. Communications from the meter to the network may be wireless, or via fixed wired connections such as power line carrier (PLC). Wireless communication options in common use include cellular communications, Wi-Fi, wireless ad hoc networks over Wi-Fi, wireless mesh networks, low power long-range wireless (LoRa), Wize ZigBee, and Wi-SUN.
ENMAX Corporation (ENMAX) is a vertically integrated utility that generates and distributes electricity, natural gas, renewable energy, and value-added services to customers in Alberta, Canada.
The Independent Pricing and Regulatory Tribunal of New South Wales (IPART) is an independent regulatory and pricing tribunal that oversees regulation in water, gas, electricity and transport industries in the Australian state of New South Wales. IPART was established in 1992 by Government of New South Wales with the primary purpose of regulating the maximum prices for monopoly services by government utilities and other monopoly businesses such as public transport.
Water supply and sanitation in China is undergoing a massive transition while facing numerous challenges such as rapid urbanization, increasing economic inequality, and the supply of water to rural areas. Water scarcity and pollution also impact access to water.
A power purchase agreement (PPA), or electricity power agreement, is a contract between two parties, one which generates electricity and one which is looking to purchase electricity. The PPA defines all of the commercial terms for the sale of electricity between the two parties, including when the project will begin commercial operation, schedule for delivery of electricity, penalties for under delivery, payment terms, and termination. A PPA is the principal agreement that defines the revenue and credit quality of a generating project and is thus a key instrument of project finance. There are many forms of PPA in use today and they vary according to the needs of buyer, seller, and financing counter parties.
An independent power producer (IPP) or non-utility generator (NUG) is an entity that is not a public utility but owns facilities to generate electric power for sale to utilities and end users. NUGs may be privately held facilities, corporations, cooperatives such as rural solar or wind energy producers, and non-energy industrial concerns capable of feeding excess energy into the system.
Water supply and sanitation in Rwanda is characterized by a clear government policy and significant donor support. In response to poor sustainability of rural water systems and poor service quality, in 2002 local government in the Northern Byumba Province contracted out service provision to the local private sector in a form of public–private partnership. Support for public-private partnerships became a government policy in 2004 and locally initiated public-private partnerships spread rapidly, covering 25% of rural water systems as of 2007.
Electricity pricing can vary widely by country or by locality within a country. Electricity prices are dependent on many factors, such as the price of power generation, government taxes or subsidies, local weather patterns, transmission and distribution infrastructure, and multi-tiered industry regulation. The pricing or tariffs can also differ depending on the customer-base, typically by residential, commercial, and industrial connections.
In 1996, Alberta began to restructure its electricity market away from traditional cost-of-service regulation to a market-based system. The market now includes a host of buyers and sellers, and an increasingly diverse infrastructure.
The electricity sector of the United States includes a large array of stakeholders that provide services through electricity generation, transmission, distribution and marketing for industrial, commercial, public and residential customers. It also includes many public institutions that regulate the sector. In 1996, there were 3,195 electric utilities in the United States, of which fewer than 1,000 were engaged in power generation. This leaves a large number of mostly smaller utilities engaged only in power distribution. There were also 65 power marketers. Of all utilities, 2,020 were publicly owned, 932 were rural electric cooperatives, and 243 were investor-owned utilities. The electricity transmission network is controlled by Independent System Operators or Regional Transmission Organizations, which are not-for-profit organizations that are obliged to provide indiscriminate access to various suppliers in order to promote competition.
The Queensland Competition Authority (QCA) is an independent statutory authority that promotes competition as the basis for enhancing efficiency and growth in the Queensland economy. It was established by the Queensland Government in 1997.
The electricity sector in the Philippines provides electricity through power generation, transmission, and distribution to many parts of the Philippines. The Philippines is divided into three electrical grids, one each for Luzon, the Visayas and Mindanao. As of June 2016, the total installed capacity in the Philippines was 20,055 megawatts (MW), of which 14,348 MW was on the Luzon grid. As of June, 2016, the all-time peak demand on Luzon was 9,726 MW at 2:00 P.M. on May 2, 2016; on Visayas was 1,878 MW at 2:00 P.M. on May 11, 2016; and on Mindanao was 1,593 MW at 1:35 P.M. on June 8, 2016. However, about 12% of Filipinos have no access to electricity. The Philippines is also one of the countries in the world that has a fully functioning electricity market since 2006 called the Philippine Wholesale Electricity Spot Market(WESM) and is operated by an independent market operator.
The Commission for Regulation of Utilities (CRU), formerly known as the Commission for Energy Regulation, is the Republic of Ireland's energy and water economic utility regulator.
