Federal Electric Regulatory Commission Revised Its Small Generator Interconnection Procedure and Small Generator Interconnection Agreement

After two years of industry consultation, the Federal Electric Regulatory Commission (FERC) has issued a final ruling on the much anticipated modification of the FERC Small Generator Interconnection Procedure (SGIP) which governs the interconnection of small generators (smaller than 20 MW) that sell wholesale electricity. The SGIP also serves as a template for state rules that [...]

Sandia, DOE Energy Storage Program, GeneSiC Semiconductor, U.S. Army ARDEC: Ultra-High-Voltage Silicon Carbide Thyristors

Increasing consumer power demand creates numerous challenges for ensuring reliable, stable power for all customers. Many energy generation technologies, particularly renewables, generate direct-current power that must be converted to alternating current before use. High-frequency silicon carbide thyristors are expected to revolutionize grid infrastructure. Power switches, known as thyristors, perform this conversion and are [...]

ECIS-Princeton Power Systems, Inc.: Demand Response Inverter

Solar energy is both predictable—the sun rises and sets everyday—and intermittent—a passing cloud can reduce a 1 MW photovoltaic (PV) array from 100% of its power generating capacity to 10% in a matter of seconds. This intermittency limits this renewable-energy (RE) source and how much of it is integrated into today’s electricity grid. A [...]
