Source of Electric Power
The majority of our power is bought from electric producers that we have agreements with to furnish us with low cost, reliable electricity. In 2009, electricity came from the following sources: Ameren Energy (49.2%), Sikeston (27.4%), Nearman Board of Public Utilities (13.4%), local plant (6.4%), AECI wind energy (1.6%), Jefferson City landfill gas (0.8%), Columbia landfill gas (1.2%).
The Columbia Municipal Power Plant is owned by the citizens of Columbia and has the capability to burn coal, gas and oil. Due to the cost-effectiveness of coal it is the primary fuel source at this time. Low sulfur coal from Kentucky is used to reduce emissions. The coal also has a high BTU content which means that more electricity can be created per ton used. The power plant is in full compliance with air quality standards set forth by the Missouri Air Conservation Commission (MACC) and approved by the Federal Environmental Protection Agency (EPA). The local plant operates only when it is cost effective and produces approximately 6% of Columbia's energy needs.
Columbia city ordinance requires Water and Light to generate or purchase electricity generated from eligible renewable energy sources at the following levels:
There is a cost cap in the ordinance. Renewable energy costs can not raise rates more than 3% over the cost of traditional sources.
In 2010, Columbia had 5% of the electric portfolio generated by renewable resources. Columbia Water and Light has agreements for energy produced from wind and landfill gas. The utility also burns waste wood along with coal at the local power plant. For more details, see the renewable energy report.

The electric transmission network delivers electricity to Columbia's grid from outside suppliers. Columbia Water and Light is in the control area of the Midwest System Operator (MISO). MISO is an independent system operator that controls the flow of electricity in northern part of the Midwest. Electricity is delivered to the customer through the distribution system.
Columbia Water & Light is responsible for construction and maintenance of transmission lines, substations and distribution lines. Water & Light crews are available around the clock to repair unexpected problems as quickly as possible
In 2007 and 2009 the utility received the RP3 award from the American Public Power Association. This award recognizes utilities that demonstrate proficiency in four key disciplines: reliability, safety, training and system improvement. Criteria within each category are based on sound business practices and represent a utility-wide commitment to safe and reliable delivery of electricity.
Columbia Water and Light has a Customer Average Interruption Duration Index of 55.97 and a System Average Interruption Duration Index of 18.27.
