"Energy Reserved" - Marchlyn Mawr HEP reservoir

Marchlyn Mawr, nestling below the rocky mountain of Elidir Fawr, with Mynydd Perfdd on the far side, is the upper lake providing the water source for the Hydro Electric Power Station in the valley below. This water can be released in less than a minute when the UN grid needs an urgent energy boost, and is pumped up during off peak cheaper times at night, from the lake of Llyn Dinas in the Llanberis Pass.
