Increased loading levels would cause a 113% overload on a 69 kV line.
The utility’s alternative, upgrading the line’s capacity and undergrounding the line, would require the utility to install 4 miles of underground cable in an area with strong anti-build sentiments at an estimated cost of $24 to $28 million.
Smart Wires SmartValves™ push power off the overloaded line to resolve the problem.
A bank of SmartValves fits in available space inside an existing substation.
This solution resolves the known overload through 2034 and can easily be scaled or redeployed as required.
