Unlike most of my classmates in Energy Technology and Policy this semester – most of whom are from the Engineering, Public Affairs or Business schools – I am fortunate to have the opportunity to join this course coming from the School of Architecture as a Community & Regional Planning student. With over half of the world’s population now living in urbanized areas, I believe it is important to have a good understanding of the ways in which cities consume energy and how we can plan for new energy technologies.
One area where I see a natural role for city planners to aid in the transition to a clean energy society is in the electrification of our transportation systems, especially with electric vehicle adoption likely to increase substantially over the next decade. (1) From a planning perspective, the mass adoption of electric vehicles represents a classic “chicken and egg” dilemma. On one hand, it is believed that many consumers are unwilling to adopt EVs without a robust charging infrastructure. On the other hand, private stakeholders are hesitant to build the necessary charging infrastructure without the assurance of strong consumer demand.(2)
In order to spur demand for EVs in the short term, forward-thinking cities have begun to develop public charging station networks. The following three case studies outline some of citing criteria that cities are using to plan for their public charging networks based on their unique land use patterns, demographic makeup and built environment.
Denver, Colorado metropolitan area
In 2010 the City of Denver, Colorado partnered with the Clean Cities Coalition and other local governments to identify 100 potential sites for public charging stations as part of a five-year plan to promote EV use in the region. The first siting criterion used by the city was to only consider off-street parking lots and structures owned by the city in order to minimize acquisition costs and other complications that might arise with private partners. Once city-owned parking facilities were identified, they were narrowed down to focus on major venues where people park for long periods of time (performing arts complex, zoo, etc.). Next, the city worked with the Library and Parks and Recreation Department to identify facilities that 1.) had excess parking spaces, 2.) were near popular private attractions (shopping/dining districts), and 3.) were geographically distributed in as many neighborhoods as possible. (3)
Seattle / Central Puget Sound, Washington
According to the City of Seattle, Washington’s Office of Sustainability and Environment, promoting electric vehicles is “an important part of the City’s efforts to reduce greenhouse gases from cars and trucks on Seattle’s roads”. While its first priority is to promote alternative transportation choices (walking, bike and transit), the city is focusing on promoting EVs to reduce greenhouse gas emissions at the street level. The consulting firm ECOtality partnered with the City of Seattle to release an infrastructure planning study outlining citing considerations for public charging stations in the Central Puget Sound area. The study determined that the most important citing consideration is that public charging stations be placed at locations where drivers will be parked from between 1-3 hours in order to get an appreciable recharge for their car. Such facilities include museums, government facilities, public parks and libraries. The plan stresses the importance of installing the charging stations near building entrances in order to maximize visibility. In addition to city-owned parking facilities, curbside charging offers a great potential for public charging stations. Through a grant from the Puget Sound Clean Cities Coalition the city is currently in the process of installing 50 public charging stations in the Seattle metro area. (4)
In 2009 the mayor of London released the EV Delivery Plan as part of a larger strategy to reduce carbon emissions in transport and improve the city’s air quality. The plan calls for the installation of 2,000 public access charging stations by 2015. High priority areas for charging stations identified in the plan include on-street parking bays in dense residential areas and in visible town centers. Special emphasis was placed on placing charging stations at or near public transit stations, including the London Underground rapid transit system and the Network Rail systems, in order to promote intermodal transportation and allow EV drivers to charge while parked for the day. As of December, 2011, 238 public charging points had been installed throughout the city. (5)
Cities that promote the early adoption of EVs stand to benefit by securing federal funds for infrastructure projects, building a “green” reputation, and attracting investment from EV automakers (6). Whatever the motivation may be, it is becoming increasingly clear that cities will play a role in the electric vehicle revolution. It is crucial for those of us in the planning field to develop an understanding of how energy technology and policy will affect the cities we serve, and what role the public sector should play in planning for the changes taking place in the energy sector.
