Microgrid system custom development costs
A 2018 study conducted by the National Renewable Energy Laboratory found that microgrids in the Continental U.S. cost an average of $2 million-$5 million per megawatt.. A 2018 study conducted by the National Renewable Energy Laboratory found that microgrids in the Continental U.S. cost an average of $2 million-$5 million per megawatt.. Goal 3: Decrease microgrid capital costs by 15% by 2031, while reducing project development, construction and commissioning times by 20%. To achieve the three primary goals, the Microgrid R&D Program works in three categories (Figure 1):. Consider an 80 kW and an 800 KW microgrid, both directing similar configurations: a solar array, two gas-fired generators and energy storage. The control system for the smaller microgrid will likely cost less in real dollars but consume more of the overall project budget than the control system for the larger one.. A 2018 study by the National Renewable Energy Laboratory found that microgrids for commercial and industrial customers in the US cost about $4 million/MW, followed by campus/institution microgrids at $3.3 million/MW, utility microgrids at $2.5 million/MW and community microgrids at $2.1 million/MW, according to Peter Asmus, research director at . . • Microgrid controller costs reported in the database per megawatt range from $6,200/MW to $470,000/MW, with a mean of $155,000/MW. • The soft cost category exhibits a high degree of variability, ranging from 1% to 75%.
