IEEE: Connexus Energy’s 10MW Solar & 15MW Energy Storage Tour
February 21 @ 10:30 am - 1:30 pm
Connexus Energy’s innovative solar-plus-storage project is now fully operational. Energization was completed at the Ramsey and Athens Township sites by December 2018. The project is one of the first in the country to use batteries integrated with a solar array to align the energy delivery to when it is most valuable. The two sites add 10 megawatts of renewables to Connexus’ energy mix with 15 megawatts of battery storage. There are nearly 14,000 solar panels alongside 1,260 batteries holding 6 megawatts of electricity.
Most solar energy is produced when there is lower demand and the price is lower. Connexus is using the batteries to time shift the solar delivery to align with system peaks that typically occur as the sun is setting or has already set. The plan is to discharge the stored energy a couple of times per month. Here is the news article: https://finance-commerce.com/2018/12/sustainable-batteries-bolster-solar-in-a-first-for-minnesota/
