On January 24, the National Energy Administration held a press conference to share updates on the performance of renewable energy grid connections in 2017, the progress of the "distribution service" reform, and the plans for clean heating in northern regions during winter. According to the data released, renewable energy accounted for 26.4% of total power generation in 2017, an increase of 0.7 percentage points from the previous year. The annual water discharge capacity reached 51.5 billion kWh, with a utilization rate of approximately 96%. Wind curtailment totaled 41.9 billion kWh, with a curtailment rate of 12%, down by 5.2 percentage points compared to the same period in 2016.
The administration emphasized that significant progress has been made in addressing wind and solar curtailment issues. Liang Zhipeng, deputy director of the New Energy and Renewable Energy Division, highlighted that through coordinated efforts, the overall operation of renewable energy grids has improved substantially. However, he noted that while the problem of curtailment has been significantly alleviated, challenges still remain. The measures taken so far have been relatively straightforward, but future solutions will become more complex as the scale of renewable energy grows.
Liang also pointed out that wind power is concentrated mainly in certain regions, such as Xinjiang and Gansu, where curtailment rates are high. In Inner Mongolia, although the curtailment rate has dropped, the large installed capacity still results in a high volume of curtailed electricity. Similarly, Jilin and Heilongjiang continue to face high wind curtailment rates. Hydropower issues are primarily found in the southwest region.
Looking ahead, the National Energy Administration plans to strengthen the use of clean energy in 2018. The strategy includes market-driven resource allocation, developing long-term renewable energy plans, reducing generation costs, implementing a renewable energy quota system, and establishing a green electricity certificate trading mechanism. These steps aim to create a new framework for promoting renewable energy production and consumption.
In addition, the government aims to reduce the amount of abandoned wind and solar power each year, with the goal of solving the issue nationwide by 2020. This includes setting clear targets for all provinces and power grid companies to ensure steady progress.
Clean heating was another key topic discussed at the conference. Guo Wei, deputy inspector of the National Electric Energy Bureau, emphasized that clean heating should be tailored to local conditions rather than being a one-size-fits-all solution. The plan involves replacing coal with natural gas, electricity, and renewable energy sources, depending on what is most suitable for each area.
In rural areas where immediate replacement is not feasible, alternatives like "clean coal + environmentally friendly stoves" or "biomass fuel + dedicated stoves" are recommended. To address cost concerns, the central government will support clean heating through existing financial channels and encourage private investment. Price mechanisms, including peak-valley pricing and residential tiered electricity tariffs, will also be optimized to reduce heating costs and promote clean energy use.
The press conference also covered the progress of the "distribution service" reform. The National Energy Administration has streamlined administrative procedures, with 72% of items either canceled or decentralized—surpassing the 50% target set by the State Council. This reform has led to lower energy costs and reduced entry barriers, fostering a more competitive market environment.
As part of the reforms, the number of power market transactions has grown significantly, with over 1.6 trillion kWh of power traded in 2017, accounting for about 25% of total electricity consumption. The establishment of 195 new power distribution pilot projects and the growth of registered power sales companies to 2,600 highlight the positive impact of these changes.
Overall, the reforms have brought tangible benefits, improving efficiency, reducing costs, and creating a more dynamic energy market. The focus remains on sustainable development, ensuring that renewable energy continues to play a central role in China's energy future.
Photovoltaic(PV)noise barriers,also known as"noise barriers with integrated solar panels"or"solar noise barrier,"combine noise reduction infrastructure with renewable energy generation. These systems are increasingly being deployed along highways,railways,and urban areas to mitigate noise pollution while generating clean electricity.
How Photovoltaic Noise Barriers Work
1. Dual Functionality
-Noise Reduction:Acts as a traditional noise barrier,blocking or reflecting sound waves from traffic or industrial sources.
-Solar Power Generation:Solar panels integrated into the barrier convert sunlight into electricity,which can be fed into the grid or used locally.
2. Design Configurations
-Transparent PV Panels:Used where visibility is important(e.g. ,along highways). -Opaque PV Panels:More efficient but block the view.
-Bifacial Solar Panels:Capture sunlight from both sides,increasing efficiency.
-Vertical or Tilted Mounting:Optimized for space constraints and sunlight exposure.
Advantages of Photovoltaic noise barrier
✅Space Efficiency:Uses existing noise barrier infrastructure,avoiding additional land use.
✅Renewable Energy Generation:Contributes to local or grid-based solar power.
✅Noise Pollution Control:Maintains primary function of reducing traffic/industrial noise.
✅Aesthetic&Functional Integration:Can be designed to blend with urban or natural landscapes.
✅Government Incentives:Some regions offer subsidies for solar-integrated infrastructure.
Challenges&Considerations
âš Lower Efficiency:Vertical mounting may reduce solar output compared to optimally tilted panels.
âš Shading&Orientation:Barriers along north-south roads may have uneven sunlight exposure.
âš Maintenance:Cleaning panels on highways/railways can be logistically challenging.
âš Higher Initial Cost:Integration of PV adds to upfront costs,though long-term savings offset this.
