In order to utilize utilise the power generated by nearly 30,000 solar panels installed on 150 acres of unused farmland in southeastern Connecticut, a regional utility needed to install a synchronous condenser to connect the solar farm to the utility’s high-voltage transmission network. The synchronous condenser was built at a utility substation near the solar farm and required a large, complex cast-in-place trench to convey water lines and high-voltage cabling to the device. Fibrelite Tier 15 load-rated trench covers were specified for this trench project and a number of similar jobs are being installed by the utility near renewable energy facilities.

With a 15,000 lb. load rating, our lightweight Fibrelite trench covers were specified for their impressive strength-to-weight ratio, allowing for manual lifting and easy maintenance checks on the water lines and power cabling. In addition, Fibrelite’s manufacturing team custom-built a number of custom-sized and angled covers to fit in the complex trench layout while still maintaining the load ratings of the covers.
