宁夏腾格里沙漠新能源基地建设稳步推进，一期项目年发电量达18亿千瓦时

Core Viewpoint - The Ningxia Tengger Desert New Energy Base is making steady progress, with its first phase generating an annual electricity output of 1.8 billion kilowatt-hours, contributing to China's energy transition through wind and solar power [2][3][12]. Group 1: Project Overview - The Ningxia Tengger Desert New Energy Base is the first project in China's "sand-gobi-desert" renewable energy base to be approved, started, and put into operation, featuring a total area of nearly 30,000 acres and over 2.2 million solar panels [3][12]. - The first phase of the project, with a capacity of 1 million kilowatts, was fully operational in April 2023, achieving an annual electricity generation of 1.8 billion kilowatt-hours [3][12]. Group 2: Ecological and Economic Benefits - The project aims to explore a dual benefit model of economic and ecological efficiency, accumulating valuable experience for similar projects [2][4]. - The vegetation coverage in the desert has increased from less than 5% to 25%, with some areas exceeding 40%, demonstrating effective ecological restoration alongside energy production [12]. Group 3: Innovative Construction Techniques - The project incorporates innovative construction techniques, such as using elevated concrete piles for solar panels to allow wind and sand to pass through, thus minimizing environmental impact [5][9]. - The design includes a "green energy + ecological governance" approach, utilizing complementary technologies to promote vegetation growth beneath and between solar panels [6][10]. Group 4: Operational Efficiency - The solar panels are equipped with tracking systems that adjust their angle to follow the sun, increasing annual electricity generation by approximately 8.9% compared to fixed systems [10]. - A 10% capacity energy storage system is integrated to manage the variability of renewable energy supply, ensuring stable electricity delivery [11].
