Solar Energy & The City of St. Louis

The City of St. Louis Sustainability Plan and its Climate Action and Adaptation Plan (CAAP) both point to using renewable energy as an important strategy for achieving the City's Climate Protection Initiative goals and advancing sustainability.  Specifically, Greenhouse Gas Mitigation Objective 2 of the CAAP is to Accelerate Clean Renewable Energy from both the source and by utilization. Strategy 2.2 of the CAAP is to Advance Community Scale Renewable Energy Options & Utilization (see pages 41-45 of the CAAP).  According to the National Renewable Energy Laboratory (NREL), Missouri has a moderate, above-average amount of solar resources: over 200 sunny days per year and an annual daily average of 4.5-5.9 kWh/m2/day. At this level, Missouri's solar resources exceed that of Germany, often considered the world leader in solar energy production.

Benefits of Solar Energy

Solar energy offers many environmental, social and economic benefits associated with the City's triple bottom line sustainability goals. Among other things, the use of solar energy can reduce greenhouse gas emissions, create job opportunities, and improve air quality.

  • Environmental: Solar energy helps lower greenhouse gas emissions
  • Social: Solar energy contributes to better air quality, health & equity
  • Economic: Solar energy can be cost-effective and lower electricity costs

Solar Energy Materials and Programs

Making New Construction Solar Ready in St. Louis

In December 2019, Mayor Krewson signed a Solar Ready Ordinance for new construction. Several new resources and supporting materials are being developed to explain how the ordinance works, and what buildings are covered by the requirements:

  • City of St. Louis Solar Ready Ordinance Infographic
  • City of St. Louis Solar Ready Ordinance Overview Slidedeck and Roadmap (coming soon)

Community Solar Opportunities

For those people who are unable to install solar panels on their property but are interested in supporting the local generation of renewable energy, in 2019 Ameren Missouri launched a Community Solar pilot program at the St. Louis Lambert International Airport. To view a time-lapse video of the solar panel construction, and/or to find more information on how to participate in a Community Solar program, visit Ameren's Community Solar website. 

St. Louis Solar Outreach & Learning

In August 2019, the City of St. Louis partnered with MOSEIA and CORTEX to hold the inaugural STL Solar Expo & Symposium. Details and copies of the Solar Symposium presentations can be found on the tab left, here. Photos from the 2019 event can be seen here.

Solar Job Training & Education Programs 

  • There are several existing programs offering solar training and education in the St. Louis area. Examples of job training and education programs are those at St. Louis Community College and the St. Louis chapters of the International Brotherhood of Electrical Workers (IBEW), National Electrical Contractors Association (NECA), and Electrical Connection.

  • The City of St. Louis Office of Sustainability is working with Employment Connection, SLATE, the IBEW and a number of other stakeholders to offer a Solar Workforce Development Pilot Project. Applications are being accepted now to participate in the Solar Workforce Development Pilot cohort.
