Monitoring the Phase 1 Output, page-25

So that's each half hour = 44MW for a full hour which is at least getting close to the 50MW nameplate. Not sure whether the 50MW is what the plant is expected to be able to produce in real-world conditions, or a theoretical maximum based on ideal conditions (temperature etc). Also I would imagine there are some performance guarantees in the design and construct contracts that would come into play if output is below expectations.
