Under the agreements, the Bald Hills Wind Farm in Gippsland, an accredited GreenPower generator, will supply large-scale generation certificates to meet the specific renewable energy requirements of each signatory.
Spokespeople from both Alinta Energy and Procurement Australia said they were excited and proud of the agreement.
"I'm really pleased that we've been able to cater to the needs of these organisations through these PPAs, following what I hope has been a smooth process for them," said Brent Graham, Alinta Energy's General Manager Commercial and Industrial.
"One of the benefits of these 10-year PPAs is the certainty it will provide those organisations and their constituents, which is important given the volatility we've seen in energy markets over the last decade," he explained.
This PPAs builds on the National GreenPower Accreditation Program which provides assurance for electricity customers that their voluntary commitments are matched with renewable energy that is added to the grid on their behalf.
Joe Arena, CEO of Procurement Australasia, said "As an organisation, we are excited by this significant milestone that will support our members for an entire decade. We are now in the process of establishing two more Renewable Energy Power Purchase Agreements, including one in Western Australia.”
The PPAs will commence from 1 July 2020.
