Potential uses of Battery Energy Storage Systems for industrial consumers

This report, commissioned by the Energy Efficiency and Conservation Authority (EECA), and written by David Reeve, Corina Comendant, Rohan Trill and Stephen Batstone, investigates the potential value of Battery Energy Storage Systems (BESS) for industrial process heat users in New Zealand. A use case for an Electric Vehicle depot is also included. The study examines how BESS can support the transition to electrification. The analysis is based on three specific industrial sites, with the aim of generalising findings to typical use cases.

The primary goal of the study is to model and optimise the value streams of BESS in industrial settings, particularly focusing on:

• energy arbitrage
• reduction of electricity network charges
• accommodating electrification loads such as heat pumps or electrode boilers, and
• co-optimised with gas boilers.

The report also explores the integration of BESS with vehicle depots at industrial sites, where the vehicles have been converted to EVs.
