Mercer Landmark started serving customers in 1933. Back then, we were a small cooperative of Ohio farmers. In the more than 90 years that followed, we’ve grown and expanded our services through Northwest and Central Ohio and West-Central Indiana.
However, we are still a locally owned cooperative with an enduring commitment to the communities we serve. Your home comfort and the profitability of your business or farm are in safe hands with Mercer Landmark Energy!
