GREEN PURCHASE POWER
Beginning June 2018, the division added a "green power" component to its wholesale power contracting to support the City's sustainability objectives. To that end, the Division purchases 20% of its energy from "renewable energy resources," or "advanced energy resources" (defined under the Ohio Revised Code). This equates to approximately 180,000 MWh of renewable energy, which is like preserving 119,745 acres (close to the size of Columbus) of lush U.S. forests. Beginning 2023, this green power commitment will increase to 50%. The division is also exploring other renewable energy options, like solar, to help the city meet its goals.
The division has long-term contracts for all power purchased, and is presently contracted for all power through 2025.

The O'Shaughnessy hydro plant is a 5 MW hydro generating unit the City owns at one of its drinking water reservoirs. This resource is not be used to meet the requirements of the division's load. However, the division is committed to operating the hydro facility as a source of energy. The O'Shaughnessy hydro unit is undergoing some mechanical and control equipment refurbishment over the next few years, which will result in increased power production.
As a public power agency, the Division of Power has been assigned 1.4 MW of "preference power" from the New York Power Authority ("NYPA"). NYPA generates hydroelectricity from the Niagara and St. Lawrence rivers. Hydropower is a low-cost source of renewable electricity and is among the most cost-effective energy sources across the board. Electricity from hydro is not subject to unpredictable price swings in the markets for energy commodities.
The Division has a power purchase agreement with Central Ohio BioEnergy (COBE), a 1.21 MW biomass waste-to-energy system. COBE processes biomass from the City of Columbus as well as regional food waste and FOG (fats, oil, and grease). Biomass from Columbus includes food waste, manure, crop waste, and biosolids from sewer and waste water. Not only does this system provide effective renewable energy, it also improves our central Ohio region by diverting organic waste from landfills and incinerators, contributing to cleaner air, water, and soil. Biogas produced through the anaerobic digestion can be used to produce electricity, thermal heat, or natural gas/compressed natural gas (CNG).
