Understanding Electricity Markets
(Abhishek Uppal)
The structure of electricity markets
Electricity is a vital commodity, with a series feature that distinguishes it from other commodities:
It is difficult to store and must be available on demand;
Rationing is usually not possible electricity or tails of clients for her;
Demand and supply vary continuously within a very short time.
There are five main participants in electricity markets:
Power generators that operate power plants;
Transmission system operators, which manages the power grid power and ensure their effective functioning;
Business electricity distribution, which serve as distributors of energy for businesses and residences;
Power traders, who act as financial intermediaries in the relationship between power generators and distribution companies of electricity;
Customers, who require a reliable supply of electricity.
Contracts are the main instruments used to regulate relations between actors in the energy markets. Usually these are held between power generators and distribution companies of electric power or energy traders. These contracts may be on a long term basis. For example, in the U.S. there is a 7-day, 24 hours of the market (a contract to provide a constant supply of energy base load) and a 5-day, 16 hour market (a contract to supply power during peak demand periods). Can also be established on short-term basis, either in the day-ahead market, or in the hour-ahead market (spot market).
What does this mean for renewables?
Analysis of conventional LCOE have renewables versus "grid parity" by asserting that the parity is the point at which the generation of energy from a source of energy becomes competitive with the electricity grid.
When parity of the mains of the alternatives are evaluated, the next day and peak hours in advance of energy prices generally have been used. These are significantly higher than the market price of 7-24, PEAKERS because more expensive gas that can be placed online within half an hour when the peak demand set the marginal cost energy in this market. These PEAKERS are more expensive than base-load coal or nuclear fuel because they consume relatively expensive, and depending on demand older, less efficient plants may need to put online.
It may be fair to compare solar to peak power, as solar panels produce more energy during the afternoon in hot, sunny days – when the power system falls short of peak production. Arguments downwind being compared to the peak power are less convincing.
However, the fact that solar and wind are intermittent sources of energy prevents them from obtaining conventional, longer-term contracts 5-16 and 7-24. Renewable energies are instead required to obtain contracts in other ways:
In the wholesale market in the "generator" to the electricity markets (eg wind farms), the fees are used in geographical areas like the EU, while the price of purchase agreements (PPAs) are commonly used in geographical areas without a supply fee. Some producers Renewables are also taking the commercial risk of the generator, with the decision to sell part of its production in the spot markets for electricity;
In the retail market in the "client" end of electricity markets (eg, rooftop solar), net metering and feed-in tariffs in geographies such as the EU have established a purchase price of renewables. Where there is no feed-in tariff, renewable power generation is sold network to spot electricity prices.
While the accumulation of the second phase, the intermittency of renewable energy generation will not be a insurmountable obstacle to the power grid. However, some studies have suggested that the penetration of intermittent sources of energy increases to about 20% of generating capacity, the network may need to be upgraded to handle the increased capacity.
All these factors depend on the specific characteristics of regional electricity markets. Investors have to assess the situation of local electricity markets, and how projects individuals are likely to play in these markets, as investment decisions – which underlines the importance of adjusting LCOE wide industry model spreadsheet from an investor, and taking wider factors into account competitive landscape.
