Plans to expand and add 300 jobs at a Newton plant have been put on the shelf. The struggling economy is outweighing some sizable incentives for T.P.I Composites, as they’ve decided to put plans for the plant’s expansion and new jobs on hold.

Those jobs would have been on top of the 500 the company promised under the incentive package that brought the wind-blade manufacturer to Newton. The state had offered another one-million dollars in a forgivable loan to help with the expansion.

Newton Mayor Chaz Allen says this is a setback, but the city will work through it. T.P.I. opened in September and has approximately 250 workers.
