Saw an announcement from Zenith Energy who build, own and operate power plants for remote mining operations. Some extracts below but seems they're not convinced of batteries over diesel at current relative prices. Battery prices need to come down further to entice them to move away from diesel.

Zenith Energy Solar PV power plant is now live and providing energy
to IGO’s Nova Nickel‐Copper‐Cobalt Operation, 360km south east of Kalgoorlie

“The proprietary hybrid system developed by the Company is able to seamlessly manage
the fluctuations in solar PV energy production to provide smooth, reliable power, without
the need for batteries to stabilise energy delivery to Nova.”
“Batteries have their place in energy systems, but they are still expensive to deploy for
these applications. Our unique, locally developed hybrid system eliminates the need for
batteries and represents a major step forward in the capital cost optimisation, operating
efficiency and environmental performance of Solar PV hybrid energy systems in remote
locations.”

“The combined 26.6MW system includes new 5.5MWp of state‐of‐the‐art PV modules,
single axis tracking, inverters, and communications and control system technology.”
