Concentrating solar power (CSP) plants are capital intensive, but have virtually zero fuel costs. Parabolic trough plant without thermal energy storage have capital costs as low as USD 4 600/kW, but low capacity factors of between 0.
How much does a solar power plant cost?
THE LEVELISED COST OF ELECTRICITY FROM CSP Concentrating solar power (CSP) plants are capital intensive, but have virtually zero fuel costs. Parabolic trough plant without thermal energy storage have capital costs as low as USD 4 600/kW, but low capacity factors of between 0.2 and 0.25.
What is concentrating solar power (CSP)?
C oncentrating solar power (CSP) is a power generation technology that uses mirrors or lenses4 to concentrate the sun's rays and, in most of today's CSP systems, to heat a fluid and produce steam. The steam drives a turbine and generates power in the same way as conventional power plants.
How much does solar energy storage cost?
Adding six hours of thermal energy storage increases capital costs to between USD 7 100/kW to USD 9 800/kW, but allows capacity factors to be doubled. Solar tower plants can cost between USD 6 300 and USD 10 500/kW when energy storage is between 6 and 15 hours. These plant can achieve capacity factors of 0.40 to as high as 0.80.
How much does a solar field cost?
In 2010, the solar field for a PTC plant cost an estimated $4503 per kW, accounting for 44 % of total installed costs . By 2020, advances in trough technology had slashed solar field costs by 68 % to just $1440 per kW, reducing its share of total installed costs to 30 % .
Can concentrating solar power be integrated with thermal energy storage?
Concentrating solar power (CSP), when integrated with thermal energy storage (TES), can address both intermittency and storage needs by providing dispatchable renewable electricity.
How much does a solar system cost?
The solar field and storage system accounts USD 4.7 million, insurance USD 3.8 million, staf costs USD 3.5 million and the power block for USD 2.5 million. The variable costs USD 1.2 million per year are dominated by miscellaneous consumables, which at USD 0.7 million, account for more than half of the total variable costs (Fichtner, 2010).
