The Vermont Public Service Board on Dec. 22 accproved changes made since its June 2016 approval of a certificate of public good for a 4.99-MW solar electric facility to be located on land within the Elizabeth Mine Superfund site in the Towns of Thetford and Strafford, Vermont.
Among other things, the CPG in the orginal approval required Elizabeth Mine Solar I LLC to make a number of post-certification compliance filings. On Dec. 1, 2016, the CPG Holder made a compliance filing that included proposed changes to the project.
The changes included a more efficient solar panel, thus resulting in fewer panels needed to achieve the same AC system capacity. The company will now use 20,592 panels of 335 watts and 345 watts, as opposed to the 22,590 panels of 315 watts as originally proposed. In addition, although the dimensions of the panels will not change, they will now be tilted at a 21-degree angle rather than 30 degrees as originally proposed.
The company also modified the electrical design in order to maximize the project’s efficiency in light of the revised solar panel type and layout. It use one 1,799 kW, one 1,200 kW, and one 1,999 kW inverter, rather than the three 1,666 kW inverters originally proposed.
The project company is a partnership consisting of Brightfields Development, which has offices at 40 Walnut Street, Suite 301, Wellesley, Massachusetts, and Wolfe Energy LLC, which has offices at 4 Kibling Hill Road, Strafford, Vermont.
