Background:
Located in Marlborough New Zealand, Dominion Salt produces salt products for a variety of uses.
Dominion Salt is a large consumer of power, which justified the installation of a 660kVA wind turbine in 2014.

The Challenge:
Excess power generated by the wind turbine was being sold back to the grid at a low price. Dominion Salt approached Vector to provide a solution for storing excess power for them it use at peak times, avoiding the cost of buying power from the grid at those times. 
The site is in a unique natural environment which experiences varied and extreme weather conditions, including earthquakes, so they needed something that’s durable and makes them less reliant on the grid. 

Vector’s Solution:
Vector developed a solution that would satisfy Dominion Salt’s current requirements and allow for future developments. The solution incorporates a Vector Energy Management System, Tesla Powerpack battery and other protection and communication components. The system is integrated to the existing wind turbine, Dominion Salt’s site control system and Vector’s operating centre, which allows for real-time monitoring and control.

Vector designed, installed and commissioned the solution and will continue monitoring throughout project lifecycle. 

Battery Specifications:
250kW / 570 kWh – enough to power 19 houses for a day.
