WS3107087921– Request for Information (ROI) - Leasing MV Network Batteries

The current opportunity

Western Power has procured three (3) Medium Voltage (totalling 8MWh / 3MW) batteries to mitigate thermal constraints. The batteries are expected to be operational by late 2021. Western Power seeks to lease the capacity of the batteries and gather evidence of a potential future model to address network needs.

Western Power is seeking suitable partner(s) to lease and operate the batteries, with the expectation that the partner will be able to seek benefits such as capacity credits, ESS, energy arbitrage & retail.

The batteries will be subject to operating parameters to ensure network benefits are realised; however Western Power will work with the operational partner to ensure value is maximised. Offers are anticipated to be baselined to unconstrained battery usage – understanding that limiting operating parameters will impact Western Power returns.

Submissions are due by 2pm (AWST) 20 September 2021.

The future opportunity

Western Power believes now is the correct time to deploy Distribution Storage as:

  • It will maximise the utilisation of the network and ensure that optimal value is extracted from existing assets.
  • It will play an important role in ensuring power system stability and security in an increasingly decentralised power system.
  • The technology has matured leading to significant advancements in capability, efficiency and reduction in cost, providing an increasingly viable alternative to traditional investment options.
  • It will facilitate further investment in renewable energy whilst assisting in maintaining a sustainable and affordable electricity supply.
  • The network benefits have been proven - Western Power has already demonstrated the benefits in front of the meter storage can provide to the network through various trials on the SWIS.
  • Recent development of advanced planning tools and scenario planning has shown via proof of concept demonstrations that correctly located distribution storage can be a no regrets investment during a time of significant change and uncertainty.

Western Power expects there to be growing opportunities for alternative services to access network values streams. The Distribution Storage Opportunities Information Paper (2020) indicates 100+MWh in the coming years. Distributed network storage is expected to play an integral role in this, with a growing fleet/s that not only provide value to the network, but to the broader energy market.

This project is the start of, what is expected to be, a larger program.
