MADISON, Wis. -

Dane County announced the opening of a new compressed natural gas fueling station at the county's on Friday.

According to a release from the county executive's office, the new filling station is a part of the CNG by 2023 plan to expand the use of cheaper and greener fuel for Dane County vehicles over the next 10 years.

The $500,000 station was paid for in part by a $150,000 grant from the State Office of Energy. According to the release, the station will more than double the county's generation of CNG to the equivalent of 250 gallons of gasoline.

The landfill station costs the county the equivalent of $1.25 per gallon. County Executive Joe Parisi said in the release the new station will save taxpayer money and help protect the environment.

"[The station] will help us greatly expand the county's conversion to a cheaper, cleaner, home-grown fuel, and increase the use of CNG vehicles in our fleet."

According to the release, the county currently spends nearly $50,000 a year on diesel and gasoline to fuel county vehicles.
