SPX estimated the grid transformer business at $1 billion a year and added that replacements should go on for several years.
The RecX project focused on transportation and speedy installation of a modularized grid transformer rather than grid standardization.
Plants have been opened by three of the largest overseas manufacturers of grid transformers: Mitsubishi Electric Power Products, Hyundai Heavy Industries, and EFACEC.
Hyundai Heavy Industries opened its Montgomery, Ala., plant in November 2011 and said it can produce up to 200 big grid transformers per year with ratings up to 550 MVA.
plants now have the apparent capacity to meet the foreseeable demand for big grid transformers. Indeed, estimated capacity of the five plants adds up to more than a typical year's imports.
