To investigate the influence of variable electricity prices on the system sizing, a variable electricity price is constructed by dividing the electricity price into a fixed and a variable part. For all scenarios, the yearly mean electricity price is kept constant at 19 € ct/kWh, which corresponds to the heat pump tariff in Germany.
Variable Speed Pumped Storage Power Plant is a high quality, photo real 3d model that will enhance detail and realism to any of your rendering projects. The model has a fully textured, detailed design that allows for close-up renders, and was originally modeled in 3ds Max 2012 and rendered with V-Ray.
