Bill, There is another metering system in use by Lakeland ELectric. The meters are from ABB (similar to the Metrima in concept). I feel sure Lakeland is collecting RECs based on these meters. Here is a link to a paper presented at the ASES solar conference last summer in CLeveland. http://www.ncsc.ncsu.edu/research/documents/technical_papers/ASES_Cleveland_final.doc
