Starting with a market survey in 2001, in 2003 in Rousse on 15th of May, the first in Bulgaria privately-owned free-access station for refueling vehicles with compressed natural gas (CNG) was opened.

The company Ecobus relied on the Italian compressor provider NUOVO PIGNONE with a more than 70 years experience and started large-scale loading of cars and passenger vehicles for the private sector in Rousse. Thus, this investment joined the list of “first things to happen” in Rousse.

Later, the expansion of this business started, with about 50 stations built in about 3 years in the country. A few years later, the massive retrofitting of the taxi sector began, with more than 100 stations in 2008.
