Welcome back to the Saturday Send, a weekly digest of stories from CommonWealth Beacon that you may have missed.

This week, Chris Lisinski takes readers inside the MBTA’s effort to electrify its commuter rail system. The T is inching forward on the project, which has been years, if not decades, in the making, moving at a pace and price that has surprised lawmakers and transit advocates alike. Without funding for further expansion of electric power, though, the next steps in the T’s ambitious electrification plans remain uncertain.

Plus, competitive electric supply groups are throwing record dollars at lobbying Beacon Hill this year, in response to legislative efforts at reforming the industry; the state’s Democratic and Republican parties, labor unions, and anti-establishment progressives have formed an unusual alliance in opposition to a ballot question that would bring all-party primaries to Massachusetts; the state’s highest court cleared the way for White Stadium to be transformed into a $325 million professional soccer stadium; and the attorney general has recovered almost $12 million from a string of settlements with companies it accuses of defrauding the state’s Medicaid program.

Check out those stories below, and, as always, thanks for reading.
