A number of manufacturers currently offer plug-in electric vehicles (PEVs) for commercial fleets, and more are preparing to bring them to market in the next few years. These vehicles span the spectrum from light duty vans and pickups to heavy-duty trucks. PEVs offer a number of benefits, but they're an expensive alternative to the vehicles you've currently got in your fleet, primarily because of their large batteries. Battery costs are declining, and manufacturers are working to develop financing mechanisms to make these vehicles cheaper to own and operate than their conventional counterparts, but for now, they're cost effective in only a few applications. At this point in the development of the PEV industry, it's all about finding the right niches, identifying and evaluating all the pieces of value that PEVs could offer your organization, and considering carefully what role these vehicles may play in the future.
