Volume risk is often used to refer to the phenomenon in which operators have uncertain amounts or quantities of consumption or production. For example, a retailer is not able to accurately predict consumer demand for a given hour for more than a few days in the future, and a manufacturer is unable to predict the exact time when it will have a facility failure or fuel shortage. A compounding factor is also the common correlation between extreme price events and volume events. For example, price spikes are common when some manufacturers are out of business or when some consumers are in a peak consumption phase. The introduction of large quantities of intermittent energy sources such as wind energy can have an impact on market prices. Buy your electricity from a renewable facility through a Power Purchase Agreement (AAE) to access long-term savings. The above measures must be adopted through an ANRE regulation, without clearly indicating whether the Energy Act will be amended by the beginning of 2020, when the internal market regulation will be applicable. Assuming that the Energy Act remains as it is, further analysis of whether the internal market regulations and the draft regulation take precedence over the provisions of the Energy Act, which requires producers to provide all the energy they produce for trade in centralised markets. The new technologies are available and have been tested by the U.S. Department of Energy, which are more suited to real-time market prices. The possible use of event-controlled SOA could be a virtual electricity market, where domestic tumble dryers can offer the price of the electricity they use in a real-time market price system.  The real-time market price control and control system could make domestic electricity customers active participants in the management of the electricity grid and their monthly electricity bills.  Customers can set limits on the amount they would pay, for example, for operating a tumble dryer for electricity, and electricity providers who are willing to transfer electricity at that price would be alerted to the grid and could sell the electricity to the dryer.
 Organized wholesale electricity markets were created to cope with the constant rise in electricity prices and to encourage innovation through competition from free businesses. In different deregulation processes, institutions and market concepts were often very different, but many of the underlying concepts were the same. Added to this is the separation of the potentially competitive functions of production and retail trade from the natural monopoly functions of transmission and distribution; the creation of a wholesale electricity market and a retail electricity market. The role of the wholesale market is to enable trade between producers, retailers and other financial intermediaries, both for short-term electricity supply (see spot price) and for future delivery times (see futures price). A new form of PPP has recently been proposed to commercialize electric vehicle charging stations through a bilateral form of electricity purchase contract. When the spot price rises, generators turn up their production or more expensive generators turn on to sell additional energy on the market. For example, a gas peak or a pumped hydroelectric plant may occur, or a rapid reaction battery can discharge electricity.
