A developer’s plans for a $210 million South Boston tower could include a combined heat and power plant to offset its carbon footprint.

Newton-based National Development proposes 265 apartments, 47,000 square feet of office space and a grocery store and retail space on the 1.4-acre site at 333 Dorchester Ave., which includes a warehouse previously owned by Marr Crane and Rigging and a Gold’s Gym. A 2-story underground garage would contain 198 spaces.

Since 2018, the Boston Planning & Development Agency has required developers of large projects to study ways to reduce greenhouse gas emissions, part of the city’s goal to attain carbon-neutral new buildings by 2050.

In a project notification form submitted Friday, National Development said it’s evaluating the use of a combined heat and power system which reuses a portion of waste heat from a natural gas-fired electric plant to provide the building’s hot water.

The development team also considered a rooftop solar array and wind turbines, but determined they are not feasible because of the small building footprint, obstruction of views and increased noise, according to the submission.

The 254-foot-tall building is the first high-rise proposed under the BPDA’s PLAN: South Boston Dot Ave. initiative approved in 2017 which allows building heights up to 300 feet in portions of the Dorchester Avenue corridor between the MBTA’s Broadway and Andrew stations.

The parcel is part of a larger 5.4-acre site that National Development said it envisions for a mixed-use development built in up to three additional phases.

National Development said it targets a fall groundbreaking.
