Large scale solar heating plants has the potential to cover more than 50 % of the yearly heat production. To reach such high heat supply fraction from solar, seasonal thermal storage is needed. Ramboll are currently involved in the design and construction of the worlds two largest seasonal storages reaching sizes of up to 200.000 m3. The energy price from these large systems can compete with natural gas boilers and some electrical heat pump solutions.
The demand for large-scale solar heating plants is expected to grow in countries with warm climates, a centralised heat supply and a progressive climate change policy.
The cost of photovoltaic (PV) systems has dropped significantly in recent years. Now utilities, investors and major electricity consumers have discovered PV in multi MW sizes for their purposes. PV is a reliable, predictable and economic way of generating renewable power. It is the quickest way to set up utility scale power generation, easily extendable and can be installed even in remote regions where access is difficult. Worldwide, more than 200 GW of PV plants are in operation now and the number is increasing fast. Over the last 10 years, Ramboll has provided services for utility scale PV installations in Europe, Africa and the Middle East.
