    Thomas & Hutton provided the site plan and layout, including access roads, two kinds of array with fixed and single axis, the spacing and layout for proper maintenance access, inverter pad sizing and location, and the fencing location, based on proper separation to arrays and the parking lot. This was the largest solar installation in South Carolina’s history and was a joint venture between TIG Sun Energy and Santee Cooper (owned by the state). In its first year, the solar farm generated 5-percent more power than projected before construction. The facility provides enough energy to power more than 300 homes.

    Colleton Solar Farm received a 2015 ACEC National Award of Recognition, as well as an ACEC SC Engineering Excellence Award in the Energy Category.
