Lake Bonney Battery Energy Storage System

About the Project

  • 25 MW / 52 MWh Battery Energy Storage System (BESS) located adjacent to the 278.5 MW Lake Bonney Wind Farm in South Australia
  • Infigen entered into funding agreements with the South Australian (SA) Government and the Australian Renewable Energy Agency (ARENA) to co-fund the ~$38 million development. The SA Government and ARENA have each committed up to $5 million in funding.
  • Construction of Stage 1 installing 25 MW / 33 MWh is expected to be complete in March 2019 and Stage 2 in May 2019
  •  Connection to the National Electricity Market (NEM) via the Mayurra substation owned by ElectraNet

Benefits

The operational benefits of the BESS are:

  1. Firming Infigen’s SA portfolio: access to energy storage allows Infigen to enter into additional energy supply contracts with commercial and industrial customers
  2. System security in the NEM: the BESS can supply ancillary services ensuring increased security and quality of supply and fast response services as required
  3. Policy considerations: adding battery energy storage capability to the SA market is consistent with the objectives of energy policy, including the proposed National Energy Guarantee
