Notes
I found official owner material confirming Beryl Energy Storage Project is 100 MW / 200 MWh and expected to commence operation in 2029, but I did not find a plant-specific greenfield total project cost announcement. Because no project-specific capex figure was located, capex remains unset rather than defaulted. For BESS, fuel cost and heat rate are not applicable. Emissions intensity is set to zero for battery storage.
