You may have noticed that turbine 1 (Tony) has generated only very briefly over the past two weeks. A contractor has established that we have an internal leak in the hydraulic system that controls the sluice gate, and is looking into what needs to be done. It’s enormously annoying, since we have plenty of head and flow for generation (which was not the case this time last year!). But it’s good that the automated control system cut in as soon as the problem occurred, so that our O&M team were immediately on the case.
