Reading into "to support bikeshare operations" I suspect that some of the MAPC awarded money is going to fund the electrification of some of the stations rather than just being a straight expansion project.
So the station electrification is planned to be funded by MAPC's federal congestion relief grant. The focus is going to be on the busiest stations. The "support bikeshare operations" in here is going to go towards subsidizing the cost of ebikes for the end user. TBD on the details of that.
