As outlined in the renewable energy ordinance, renewable energy cannot cause electric rates to increase more than 3% above what rates would be with non-renewable energy.
For calendar year 2013, the additional cost to address the renewable portfolio requirement was $1,186,609 and the limit was $3,253,064. The extra money spent on renewable energy was 36.5% of what was allowed according to the ordinance.
The city shall 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 increase electric rates more than 3% higher than the electric rates attributed to the cost of electricity generated from 100% non-renewable sources. See the City of Columbia Code of Ordinances for the full text of the mandate.
NOTE: The renewable energy ordinance was revised by the Columbia City Council on January 6, 2014. The percentage of required renewable energy increased from 10% to 15% by 2018, from 15% to 25% by 2023 and set a new goal of 30% by 2029.
