Distributed generation (DG) is a supply technology that can be at or near retail load, enabling smart buildings and power park/premium operating districts, providing high-quality, 99.999% reliability. Combined with on-site energy storage, DG is a disruptive technology transforming centrally managed radial delivery infrastructure into a geodesic network, providing higher resilience of the power system and enabling consumer integration into energy markets. Traditionally more associated with high-availability fuel cells, increasingly renewable solutions, most notably photovoltaic (PV) solar, are being included as part of a DG solution.
