How effective is a solar panel in Columbia? See the data from a photovoltaic panel at the Columbia Career Center.
The majority of our power is bought from electric producers that we have agreements with to furnish us with low cost, reliable electricity. In 2006, these suppliers contributed the following percentage to Columbia's electric portfolio: Ameren(40.4%), Sikeston(33.5%), Nearman Board of Public Utilities(9.3%), the wholesale market(8.9%), local plant(7.6%), Columbia Energy Center(0.2%).
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 7% 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:
The cost of the renewable energy mandated in the ordinance must not be more than 3% of the cost of electricity derived from non-renewable sources.
In 2008, Columbia will surpass the 2% level of renewable energy required by the renewable energy ordinance. Columbia Water and Light has agreements for energy produced from wind and landfill gas. With these three projects, the utility will accomplish the 2013 target of 5% by the end of 2008. Total costs of each project will be below the 3% threshold cost set by the ordinance.

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 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.
