The intention of this solicitation is to enable station owners and/or operators to invest in O&M activities that will result in long-lasting improvements to station reliability and the customer experience.

Where appropriate, station owners and/or operators may also make station investments to address immediate problems facing customers, including but not limited to bringing stations temporarily out of service back into service.
