The levelized electricity cost of concentrating solar power plants depends on both the available solar resource and development costs of investment, financing and operation. Plants under the same price and financing conditions in the south western United States or upper Egypt, will have a levelized electricity cost 20% to 30% lower than in southern Spain or the north African coast. This is because the amount of energy from direct sunlight is up to 30% higher (2600–2800 kWh/m2 a year compared with 2000–2100 kWh/m2 a year). The solar resource is even lower in France, Italy and Portugal, while the best solar resource in the world is in the deserts of South Africa and Chile, where direct sunlight provides almost 3000 kWh/m2 a year.
