The buyer is typically a utility or a company that purchases the electricity to meet its customers' needs. In the case of distributed generation involving a commercial PPA variant, the buyer may be the occupant of the building—a business, school, or government for example. Electricity traders may also enter into PPA with the Seller.
Distributed generation and storage enables the collection of energy from many sources and may lower environmental impacts [citation needed] and improve the security of supply. [5] One of the major issues with the integration of the DER such as solar power, wind power, etc. is the uncertain nature of such electricity resources.

The new fleet has 11.5 GW of generation (46% natural gas generation, 31% coal generation, and 15% oil generation) in Texas, 9.7 GW of generation in the East, and 2.6 GW of generation in the West. [9] In March 2018, NRG Energy acquired XOOM Energy, a retail electricity provider, for $210 million.
IEEE 1547-2003 had a tight underfrequency protection setting of 59.3 Hz which posed a risk for grid stability. In case of an underfrequency situation, [3] e.g. after a major loss of generation, the situation may get worse when a multitude of distributed energy resources (DER) disconnect simultaneously.
The electricity generated by each customer's "shares appears as a credit on his or her energy bill, a savings expected to average between $4–$50 a month, given sunshine variability. For a monthly fee—starting at $10.75 a month (averaging 9%) for a 0.5 kW system—participants opt into solar power production.
In centralized power generation, only local control of generation is necessary. This involves synchronization of the generation units. In distributed power generation the generators are geographically distributed and the process to bring them online and offline must be carefully controlled. The load control signals can either be sent on ...
Stationary fuel-cell applications (or stationary fuel-cell power systems) are applications for fuel cells that are either connected to the electric grid (distributed generation) to provide supplemental power and as emergency power system for critical areas, or installed as a grid-independent generator for on-site service.
