PMLD RENTAL PEAK SHAVING GENERATOR

PMLD has rented a two-megawatt peak Shaving Generator for the second consecutive summer. The generator, located at the wind turbine site, runs for 4 hours, 3-4 times per month on average. The goal is to reduce our transmission peaks for each summer month and reduce the annual capacity peak. During the summer of 2021 we were able to reduce our transmission peaks by two megawatts each month from May to August. The annual capacity peak which occurred in June was also reduced by two megawatts. The net benefit to PMLD was $142,391.96 in avoided transmission and capacity charges.

We are in the process of gathering specifications for a Battery Storage System that will accomplish the same peak reductions without the carbon footprint of a diesel generator. Due to supply issues and an increased demand for this technology, the battery will not be online until 2024/25.
