According to the U.S. Energy Information Administration, in the New England region of the United States, the increase in small-scale, distributed photovoltaic solar power generation is changing the local spring (March-May) hourly metered electricity demand curve. Small-scale solar photovoltaic systems are generating less than A 1MW system, usually not metered by the utility. Because of this increase in distributed solar generation capacity in New England, the utility's electricity demand decreases rapidly in the morning and increases rapidly in the evenings throughout the spring. New England has added 3.8 gigawatts of solar power capacity since 2016, despite being less solar-rich. Distributed solar generation increases rapidly in the morning, causing electricity demand to drop; while distributed solar generation decreases rapidly in the evening, causing electricity demand to rise. Because utility grid operators typically dispatch solar capacity first, they must add or subtract other types of generation to meet and balance power demand. More than half (or 2.3 GW) of the 3.8 GW of new PV capacity added in New England since 2016 has been small-scale solar. Since small-scale solar is not metered by the utility, it is on the hourly grid monitor It is impossible to distinguish it as a power generation source. The increase in small-scale solar generation has changed the average hourly rate of change in electricity demand in New England. From March to May 2016, hourly electricity demand in New England typically increased by 500 megawatts over a three-hour period between 8:00 a.m. and 11:00 a.m. Electricity demand during this period is typically reduced by 800 megawatts by 2022. Likewise, in spring 2016, nighttime electricity demand typically increased by 800 megawatts between 4:00 p.m. and 7:00 p.m. By 2022, the electricity demand for these three hours will increase by 1,900 megawatts.
