PROVIDENCE, R.I. (AP) - A company says it's beginning construction on what will be the onshore wind farm with the most operational capacity in the state.

Green Development LLC, is building a seven-turbine wind farm in Johnston, R.I.

It says its turbines, at 3 megawatts each, will be fully operational by the year's end, for 21 megawatts.

Green Development says it also owns 10 turbines in Coventry, but they're 1.5 megawatt each, for a capacity of 15 megawatts.

The North Kingstown-based company says it's dedicated to creating "green jobs and green energy."
