大型太阳能光伏能源与比特币挖矿联合发电系统的经济技术评估

Abstract The limitation of fossil resources and the consequences of global environmental and climate change have created suitable opportunities for solar energy to compete with fossil energies, especially in countries with high radiation potential. The purpose of this research is to investigate and evaluate the technical and financial aspects of a joint investment in a cryptocurrency mining center and the construction of a large-scale solar power plant to supply the electricity needed in the Bitcoin mining process. Comparing the standalone 10 MW solar plant with the solar–cryptocurrency cogeneration model, the solar-only option shows low financial viability with a 10-year payback and 5.07 % IRR, whereas the combined model achieves payback in 2–5 years and a 33 % IRR. Monte Carlo analysis confirms robust performance, with IRR reaching 54 % and NPV exceeding 11 million USD at 95 % probability. Consequently, the standalone solar project is unappealing to private investors because of low returns, delayed payments, and financial risks, whereas the solar–mining model is highly attractive, offering dual revenue streams, lower liquidity risk, and increased grid energy supply after the mining phase. The proposed solar–cryptocurrency mining model not only provides a financially attractive investment but also delivers significant environmental benefits by avoiding roughly 10,457 tons of CO 2 emissions annually, promoting sustainable energy use, and supplying surplus electricity to the national grid.
