Mercury has agreed a long-term Corporate Power Purchase Agreement with Amazon for renewable energy for their Auckland data centres, planned for launch in 2024. Amazon will purchase around half the real time output of Turitea South (the southern section of Mercury's Turitea wind farm) for an agreed price. Turitea South is 103 megawatt (MW) and expected to produce 370 gigawatt hours (GWh) per annum.

The financial terms of the deal are confidential. The renewable energy from Turitea South will be used to support Amazon Web Services's (AWS) data centres in Auckland, when they launch in 2024. While Mercury has a strong pipeline of renewable development, having a guaranteed consumer buying a significant amount of Turitea South's generation means that Mercury NZ remains well positioned to continue developing renewable projects at pace.

A PPA (power purchase agreement) is an electricity supply agreement, where a price is agreed for a period of supply. For the generator and the customer, the agreed price avoids the volatility risk of buying and selling on the Wholesale energy market, where the price moves around depending on current and forecast supply and demand.
