Each has 50 MW of power and 200 MWh of storage capacity. Haber Paper calculates combined ratings of 150 MW and 600 MWh; dividing nominal energy capacity by power gives four hours. That ratio explains the storage timescale. It does not guarantee full delivery under every condition, annual output or a fixed period of protection against outages.","Power determines how much a battery can deliver at one time, whereas MWh determines how much energy it can hold. These constraints affect different services. Rapid power delivery matters for a short frequency disturbance; usable stored energy matters for support throughout an evening. The nominal four-hour duration assumes adequate initial charge, the stated power and available capacity. Reserving part of the charge for another service can shorten peak support. The announcement does not report the actual daily allocation of these services.","A simple stress calculation illustrates why energy and service should be separated. Maintaining 150 MW from the three facilities for eight hours requires 1,200 MWh, twice the announced nominal 600 MWh. This arithmetic assumes zero losses and is not a forecast. Without an opportunity to recharge, that requirement cannot be met from the stated nominal energy alone. Lower power could theoretically extend support, but system needs, reserved charge and the battery’s permitted operating range also matter. Metered operations must establish how much energy is actually delivered.","Economic value similarly cannot be read straight from capacity. A battery can shift energy between hours with different prices or loads, while supplying rapid response and reliability services. The same energy reserve cannot be allocated in full to several simultaneous commitments.

Debt must be repaid and should not be treated as economically identical to another support instrument; scope and financing structure must remain visible.","The release’s approximately 90,000 tonnes of annual emissions reductions is an expectation, rather than a measured annual result. Environmental outcomes depend on the generation used for charging and the generation displaced during discharge.
