A static inverter plant of HVDC Directlink is located at Laverty's Gap near Mullumbimby. This inverter plant was previously the site of a 288 kW hydroelectric power scheme that powered Mullumbimby, Byron Bay and Bangalow from 1926, using water from a weir in nearby Wilsons Creek. The scheme was the fourth hydro electric power station in NSW and only the fifth on mainland Australia. Powering Mullumbimby for the first time in 1925, the scheme made Mullumbimby one of the first country towns in NSW to receive electricity. Although decommissioned in 1990, it is now of state heritage significance. The hydroelectric scheme was designed by William Corin (1867–1929). The site is being considered for pumped-storage hydroelectricity.
