For over 30 years now, loyalty and transparency in our work have always been our objective. We strongly believe in the public interest; therefore, we are fully consumer-oriented and our mission is to provide full access to the cheapest and most environmentally friendly energy, i.e. natural gas. We respect the right of choice and are most anxious that our customers make informed decisions. We adhere to the principles of good commercial practices and accept market rules as an incentive for development.
We have invested over 320 million Euro in the construction of 2,400 km of distribution pipelines. We reached the homes of nearly 250,000 Bulgarian households. Every month we provide an energy alternative to over 60,000 families, over 3,000 manufacturing companies, hundreds of schools, kindergartens, hospitals and social institutions.
Natural gas has always been the most affordable energy for society. Together, more than two decades ago, we started the gasification story of Bulgaria, which with zeal and desire we, Overgas, and you, our friends and partners, will continue to write. Together, we traveled the long and thorny path of changing the status quo and building a functional energy market. Because we have always advocated the right of choice. Because we are on your side. Because we are alike.
