As technologies for alternative energy production advance, municipalities in the Delaware Regional Planning Commission (DVRPC) region have continually been faced with questions about how to regulate them at the municipal level. In 2009, at the request of the City of Philadelphia and Montgomery County, DVRPC established the Alternative Energy Ordinance Working Group (AEOWG) to bring together leadership from counties and municipalities in the DVRPC region to compile resources to support the safe and sound development of small-scale alternative energy systems, including solar photovoltaic (PV), small wind, and geothermal. This case study focuses on the expertise and activity in the region to develop a series of model Alternative Energy Ordinance Frameworks (AEOF) that provide resources on zoning for solar, geothermal and wind energy systems. These frameworks will be accessible in 2012 via an online portal. The goal of the AEOFs is to help municipalities develop appropriate zoning for alternative energy systems.
