On June 18th, 2018, Henan Power Grid’s 100 MW energy storage demonstration project—the Luoyang Huanglong station containerized battery storage project—completed its successful connection to the grid.  The project marks a critical step for grid-side distributed battery storage in China.  The project will provide Henan Power Grid with load shifting services and promote the use of renewable energy within the grid.  The project is the first grid-side 100 MW scale distributed battery storage demonstration in China.

The grid faces a number of challenges, including the rapid addition of renewable energy, ensuring safe operations, finding suitable peak shaving methods, and financing of new construction.  Large-scale battery storage provides response time in milliseconds, providing safe and speedy power support to the grid.  Battery storage also provides new strategies for peak shaving and limiting air pollution, and can increase the efficiency in which energy is utilized in a variety of ways.

The Henan Power Grid project has been led by the Pinggao Group (a subsidiary of China State Grid) with construction by Luoyang Power Supply company.  The project includes 16 substations in nine regions, including Luoyang and Xinyang.  The plan utilizes distributed deployment, modular design, independent connections, and centralized dispatch. 

Now that the project has successfully connected to the grid, Pinggao Group is expected to increase project construction speed to complete the remaining project components. The project is scheduled to be fully complete before the end of 2018.  Pinggao Group has in recent years been an active promoter of large-capacity battery storage technology and innovative business models.  The successful implementation of the Henan Grid project will be an important trial for the use of large-capacity distributed battery storage, and a significant contribution to the goals of the Guiding Opinions on Promoting Energy Storage Technology and Development.  The project creates a basis for commercialized applications and sustainability in the power grid, and is an important step for China in the advancement of the energy revolution and energy internet development.

ESIE 2018 Media Report – Which Energy Storage Application has the Greatest Prospects for the Future?

Author: DiDi Beijixing Energy Storage Online

power-2881462_1280.jpg

In recent years, the value of energy storage has become increasingly clear, whether in behind-the-meter, ancillary services, renewable integration, or other applications.  Yet when it comes to economic benefits, energy storage business models are still in an exploratory stage.  There are still many questions to be answered. What direction can energy storage develop in in the future?  How do we uncover energy storage’s potential? The author visited the 7th annual Energy Storage International Conference and Expo (ESIE 2018) to learn more about the future of energy storage in China.

According to statistics from the CNESA Global Energy Storage Project Database, as of the 2017 year’s end, China’s total operational energy storage capacity totaled 28.9GW, an increase of 19% from the previous year.  Pumped hydro energy storage made up the majority of this capacity, at nearly 99%. Electrochemical energy storage capacity totaled 389.8MW, an increase of 45% from the previous year. In a comparison of new electrochemical energy storage capacity by applications, in 2017, behind-the-meter energy storage made up 59% of the total of new applications.  Renewable integration came in second at 25% of the total new applications.

Energy Storage Provides New Energy with “Value-Added Services”

As the use of New Energy sources continues to increase, the energy structure faces a transformation.  In the future, as solar, wind, hydro, and other New Energy sources occupy a major portion of China’s energy supply, energy storage will be an important part of the country’s entire energy industry. In recent years, China has promoted multi-energy systems, wind+storage/solar+storage, and other demonstration projects.  Energy storage not only contributes to a more effective use of energy, decreasing wind and solar curtailment, it can also stabilize power generation, increase the quality of electric energy, and contribute to the balancing of grid loads.

Take solar PV as an example.  In its earliest stages, the manufacturing costs for solar PV were high, and companies focused most of their efforts on lowering such production costs and technology R&D.  With the maturation of the market and technological breakthroughs, solar energy manufacturing costs fell rapidly, bringing about opportunities for energy storage.  Energy storage can help to improve the quality of PV electricity and ease pressure on the grid.  Currently, there are many solar+storage projects in operation which help to prove through practice the value of energy storage in new energy grid integration.

Once such project is located in Shaanxi.  In 2017, Shaanxi Province’s Dingbian County achieved a total installed PV capacity of 1500MW.  In 2016, the county’s solar curtailment rate was near 10%.  The 10MWh Dingbian Li-ion battery system’s load shifting program brought relief to the curtailment issue.  The project utilized Dynavolt’s MW-scale container-style battery module technology.  Operating in conjunction with the PV station, the battery absorbs excess power, activating based on PV power prices, providing load shifting services and contributing to use of local power.

Marketization is the Outlet for Energy Storage in the Grid

The five stages of the power system—generation, transmission, transformation, distribution, and end use—all can experience the value of energy storage.

In electricity generation, energy storage can participate in ancillary services such as frequency regulation and peak shifting.  However, China’s ancillary services market is still in an exploratory stage, and questions such as proper pricing and transaction mechanisms have not yet been resolved.  While some companies have implemented frequency regulation projects, many energy storage enterprises planning to join the ancillary services market are still waiting and watching the market from afar. At present, the most frequent approach to frequency regulation is through energy storage combined with thermal generators.  As individual regions build their own ancillary services markets, energy storage in the form of peak shifting and frequency regulation has a strong chance at commercialization.

Amongst energy storage in ancillary services projects, Beijing Ray Power has created a combined energy storage and thermal generator system which functions as a new frequency regulation source that not only resolves the slow adjustment time, delays, and potential for errors of traditional thermal generators, but also removes the difficulty of adding frequency regulation to the grid due to energy (KWh) limits on energy storage. One example is the Jinneng Group’s 9MW solar-thermal power plant in Shanxi that links energy storage with frequency regulation.  The system relies on a thermal generator coupled with a 9MW/4.5MWh energy storage system. The remodeled generator system has an improved AGC frequency regulation performance factor Kp of nearly 5.0.  The energy storage system’s round cycle efficiency is nearly 88%, while the power plant’s AGC frequency regulation compensation helps create profit, bringing great benefit to the company.

The transmission and transformation side of electricity is unlikely to see energy storage applications in China.  The size and relative staunchness of the Chinese power grid in comparison to those of other countries means that energy storage opportunities in China’s transmission and transformation will be unlikely for the next few years.

Power distribution, as many know, is one of the weaker components of China’s power system.  One example is Guangdong, where numerous areas of the province have suffered from low voltage problems in distribution and transformation, leading to significant customer complaints.  Such incidents brought energy storage into focus.  However, according to insider information, the cost for a new energy storage system would be at least twice as much as that for transformer and line upgrades.  Such costs are a difficult challenge for energy storage, but if over time the costs of energy storage batteries decreases, power distribution is certain to be a large market for energy storage.

Behind-the-meter energy storage made up the majority of 2017’s new energy storage capacity in China.  No matter if used for load shifting or demand management, the value of behind-the-meter storage has already been proven.  From the point of view of businesses, the most common profit point lies in energy arbitrage.  Yet relying completely on arbitrage is not enough to bring out the complete value of energy storage.  Even extremely low costs will not be enough to bring out the best regulatory functions of energy storage.

Narada Power’s smart energy storage power station at the Wuxi-Singapore Industrial park serves as a demonstration of energy storage capabilities.  The station is powered at 20MW, and total capacity of 160MWh.  The facility is currently the world’s largest commercialized energy storage power station in operation.  Each day, the facility can provide the industrial park with 20,000KVA of load adjustment during peak periods, lowering the burden on the industrial park’s substations and transformers and eliminating the need for transformer upgrades.

Second-Life Usages for EV Batteries are Another Driving Force for Energy Storage

electric-car-1458836_1280.jpg

In 2017, over 777,000 new energy vehicles were sold.  According to predictions, China will soon be facing a large wave of battery retirement.  China has already released a number of policies to stimulate the development of the battery retirement industry.  Recycling of retired batteries can be done in one of two ways, either through disassembly of the battery or through second-life applications.  Second-life applications have several advantages.  Currently, the cost of new battery production is high, a major factor limiting the widespread deployment of energy storage.  Second-life usages help lower the initial construction costs for energy storage systems, while at the same time being environmentally friendly and having a positive socioeconomic value.

In recent years, many domestic and international agencies have undertaken second-life applications research.  In China, there have been three main industry groups that have engaged in such research.  The first is electric vehicle manufacturers, such as BYD and BAIC BJEV.  The second group is energy storage customers, such as China Tower and grid companies.  The final group is third-party energy storage groups such as Shanghai GMDE.  Internationally, the main participants in second-life battery research are car manufacturers.

Second-life EV battery projects have already been successfully launched in China.  In February 2018, Shanghai NIO completed construction of two second-life energy storage power stations.  Beijing Pride Power complete a MWh-level second-life battery system, the first application of its kind in China.  The system uses retired vehicle battery packs (lithium-iron phosphate batteries), a bidirectional PCS, and connects to the end-user distribution network through a low-to-medium voltage distribution room.

Second-life applications can lower the investment costs of new projects and shorten the return period.  Although many companies have already become involved in second-life applications, there are still many areas that require exploration and improvement:

1.       Safety Considerations – early model batteries suffer from relatively low performance and were not designed with recycling in mind.  Designs also vary greatly in size and parameters, and it can be difficult to trace complete information on the batteries.  These and other concerns create large safety issues for second-life battery usages.

2.       Technological Considerations – second-life EV batteries must go through testing, disassembly, reassembly, and other stages.  Currently, the testing process suffers from a lack of advanced technology and standards.  Most testing is done by hand, and early stage batteries do not have a unified standard for testing, creating difficulties in the reassembly of batteries.

3.       Cost Considerations – EV battery disassembly, testing, and reassembly cost a great deal in resources and manpower.  Without developed technologies for such processes, many companies face added costs for second-life battery projects.

As EV battery retirement increases, and with the support of national policies, second-life batteries are destined to become a thriving market.

Increased policy support and continued research breakthroughs lowering the cost of energy storage are helping to develop the energy storage industry in a positive direction.  Whether in microgrids, ancillary services, spot markets, or any other field, the future of energy storage looks bright.

Lishen Enters 21700 Li-ion Field With New 15 GWh Suzhou Production Facility

During a press release on July 20, 2017,  CNESA alliance member and Li-ion manufacturer, Suzhou Lishen, announced that operations have begun at a recently completed 353,000 sq. meter facility with a planned yearly production capacity of 15 GWh. Suzhou Lishen is a subsidiary of the Lishen group based in Tianjin, China.

The company’s East China production base is a central focus point in the company's “13th Five Year Plan” strategy, which includes plans increase production capacity for Li-ion batteries used in electric vehicles. The total project investments total over CNY5 billion (US$7.5 million) 

Suzhou Lishen invested CNY2.1 billion over the first two stages of the project, constructing a production capacity of 4 GWh. On April 15, 2016 construction began, with operations beginning on July, 20, 2017. It is China’s first domestic facility to manufacture the 21700 format Li-ion batteries.

Lishen’s 21700 format batteries have four main advantages when compared to the traditional 18650 batteries. The monomer energy density is higher, the battery system costs are lower, the total batter casing is lighter, and its overall easier to automate production. In addition to this, the Lishen 21700 have three core design features:

  1. An entirely new physical composition battery cover that ensures consistent performance and minimizes the safety risks associated with voltage leaks
  2. The battery casing uses nickel-steel pre-plating, putting an end to the need to produce metal powder, overall reducing battery self-discharge
  3. Quadrapole structure allows for super high power discharge and high performance.

During the press release, Lishen unveiled the 21700 series products, suitable for a range of vehicles including hybrid electric vehicles, plug-in hybrid electric vehicles, and battery electricity vehicles. At the same time, the battery series products can satisfy the power requirements for 12V start-stop systems as well as 48V micromixing systems. Lishen has entered into agreements with 10 domestic suppliers for parts and components, with total purchasing plans exceeding CNY5 billion.

Draft Standards Released for Energy Storage with Wind/PV Plant Design

China’s Ministry of Housing and Urban-Rural Development (MOHURD) this weekend released a draft standards proposal for grid-connected wind and solar + storage plant design where storage is installed in conjunction with either wind, solar, or wind-solar hybrid plants. The proposed standards would apply to all new construction, expansions, and renovations to wind and solar generating assets rated at 10 MW and above designed with accompanying electrochemical storage equipment. The standards do not require all wind, solar, and wind-solar hybrid plants to include storage, but instead guide the design of facilities constructed with storage in mind.

The standards, based from the results of various optimization tests, make the following recommendations based on the principal application of the storage resources. 

  1. Output smoothing mode: for storage assets used to correct for sharp fluctuations in wind and/or solar output. Installed storage should be no less than 10% of generation power with discharge capacity no less than 0.5 hours. 
  2. Output tracking mode: for storage assets used to aid wind and/or solar plants meet the power dispatch commitments. Installed storage should be no less than 30% of generating power with discharge capacity no less than 1 hour. 
  3. Frequency regulation mode: to regulate generation output frequency. Installed storage should be no less than 20% of power generation rating. No discharge time standard provided. 
  4. Peak shaving/valley filling mode: further recommendations will be made based on grid needs. 

Comments for the proposed standards are requested to be submitted before July 28, 2017. It is not yet clear whether the proposed standards will be legally binding are provided instead as design guidelines.

Australia, meanwhile, after recently announcing plans for a 129 MWh Li-ion battery system as part of a wind farm in South Australia, is considering similar standards for renewable generation-sited energy storage. Minister for the Environment and Energy, Josh Frydenberg, recently proposed a “generator reliability obligation” suggesting  25% capacity and 4 hours of storage as guideline, conceding the exact figure would ultimately be up to the Australian energy market operator, AEMO.

China's NEA Calls for Energy Storage in Peak Services, DER

On February 10th, the NEA released its “Guiding Opinions on Energy Development for 2017” (2017年能源工作指导意见). In the context of broader targets laid out in the 13th Five Year Plan, the document represents a more detailed outline of development goals for 2017. In particular, the "Guiding Opinions" fleshes out the main tasks and goals for subordinate agencies to implement over the upcoming year, in line with the CPC’s strategic "energy revolution" initiative promoting a coordinated international cooperation advancing energy supply, systems, technology and consumption known as“Four Revolutions, One Cooperation" (四个革命、一个合作).

"Guiding Opinions" mentions energy storage several times as a key technology to develop in the upcoming year. In particular, the NEA identifies energy storage in the following sections:

"Strengthen and Reinforce Weaknesses in the Energy System"

The NEA calls for the need to increase peaking services and increase the grid system’s operating efficiency, through ameliorating power infrastructure bottlenecks and optimizing system-wide adjust-ability and flexibility.  To this end, the NEA promotes establishing an ancillary services market and compensation system along with accelerating the use of natural gas peaker plants. They also call for increased trials in fast-response coal power equipment, and promote continuing energy storage project demonstrations.

"Upgrade Energy Technology Equipment"

In this section the NEA identifies key technologies such as nuclear, renewable energy, shale gas, coalbed methane, gas turbines, and high temperature materials used in offshore oil and gas exploration. Additionally, they propose increase application of thermal solar storage uses and large-scale storage systems in conjunction with distributed energy systems.

The NEA also raises the need for establishing a strong standards body to guide the emerging “Internet+” Smart Energy field, electric vehicle charging, solar power generation, and energy storage industries.

"Social Welfare"

As part of energy substitution methods to decrease pollution and quality of life, the NEA mentions the need for improvements in peak and off-peak electricity pricing mechanisms in conjunction with encouraging adoption of energy storage and heat storage.

"Specific Engineering Tasks"

While this section consists of numerical targets implementing gas peaker plants, pumped hydro stations, and inter-province transmission and distribution tasks, the NEA is more cautious with energy storage, where instead of setting a numerical capacity mandate, rather lists off several key projects under construction with plans to finish within the year.

 

The 2017 "Guiding Opinions" in contrast with the the 2016 edition does not mention specific battery chemistries but sets more specific goals including the call for a standards body, and a more clearly defined potential and need for energy storage in peaking services and distributed energy resources. The 2016 edition called for developments in large-scale energy storage, in particular for all vanadium redox flow batteries, but was less clear regarding the role energy storage can play in the grid. Compared to 2016, the 2017 "Guiding Opinions" does show some evolution of the NEA's thinking regarding the technology. This year, a "Guiding Opinions" focused specifically on Energy Storage development is also expected. 

  

CNESA Co-hosts Forum on Storage Pricing

December 10, 2016 - CNESA, in collaboration with the Beijing Energy Club alongside the Asia Development Bank, hosted the international forum: “Energy Storage Pricing: Method and Mechanisms.” Hearing from both Chinese and international experts in power and storage markets, the forum served to illuminate storage investment and accompanying policies as well as viable business models in some of the world's principal markets. Speakers also discussed applications in the Chinese market with potential storage pricing policies and mechanisms under China’s power system marketization reforms.

Morning sessions were devoted to international perspectives on storage pricing mechanisms. Janice Lin of Strategen Consulting introduced the American market and various pricing and government-backed incentive schemes underway across the nation. Heiko Staubitz, of Germany Trade and Invest, introduced the German renewables market and major economic drivers behind storage profitability. Goran Strbac from Imperial College London, presented his research on power systems markets and Naoki Sakai with the Asian Development Bank introduced storage pricing in Japan.

The afternoon session was headed by Chinese speakers including CNESA Secretary General Tina Zhang, delivering her thoughts on energy storage and China’s 13th Five Year Plan, along with the National Development and Reform Commission head of the Pricing Institute Liu Shujie spoke on an energy storage demonstration project in Dalian, Liaoning Province along with preliminary insights into setting Energy storage pricing mechanisms. Over 160 industry representatives, government officials, and researchers were in attendance.

Sunday, following the forum, members of organizing committee visited CNESA Alliance member, Rongke Power's energy storage R&D and production center.  Rongke's storage division, founded in 2008, is one of the world's leading vanadium flow battery solutions providers. Rongke Power serves as a core member of the Chinese Academy of Sciences Dalian Physical Chemistry Research Institute. Beginning research into vanadium flow battery technology in 2000, the company has grown with over 30 technology projects located across China, Europe and the United States today. 

Li Keqiang Calls for Breakthroughs in Storage Technology

Chinese Premier, Li Keqiang, who also serves as Chairman of the National Energy Committee, recently emphasized the central role of transforming energy production and consumption in sustainable development at an NEC meeting on November 17, 2016. Premier Li highlighted the need for breakthroughs in energy storage technology to effectively exploit China’s rapidly growing renewable energy capacity.

The National Development and Reform Commission (NDRC), National Energy Administration (NEA), National Energy Committee members, and other experts shared reports on their research. Premier Li, who presided over the meeting expressed the following, giving a view into the policy direction and priorities of the Communist Party. Li expressed that energy strategy is the pillar behind national development. At present, considering rapid changes in energy technology and changes to the global composition of energy supply and demand, China, as one of the world’s major energy exporters and consumers must capture the new opportunities. Li indicated that the Party will work to implement practical development plans, with supply-side reforms as the central theme. In all, the government aims to increase China’s competitiveness in the global energy industry, constructing clean, low-carbon, safe, and efficient energy systems, to support China’s continued stable and sustainable economic development.

Sustainable energy development, Premier Li continued, relies on technology innovation and system reforms. He called for concentrated efforts to develop and exploit renewable energy resources, especially by way of grid integration, storage technologies, and breakthroughs in microgrid research. Through the Internet of Things construction of the “Internet+” and smart energy, China will upgrade the grid system adjust-ability, increase consumption of alternative energy sources, and develop highly advanced and efficient technology. Li expressed the need to actively encourage entrepreneurship, innovation, and the founding of new energy technology companies. While intensifying reforms in energy-related State Owned Enterprises, Li also signaled support of privately run enterprises entering the energy sphere. Such support can be achieved through marketization reforms, simplifying the regulatory processes, and transferring more rights to local governments, along with reforms in oil & gas drilling rights and reorganization of power transmission and distribution systems. Ultimately, the government aims to improve and encourage the development of distributed energy resources related mechanisms and policies, display the impact of market resource allocation, and the role government can play, all to establish a fair and competitive energy market.

To ensure energy security, Premier Li points out that China must take domestic and international concerns into mind, though based domestically, China must also look abroad for international cooperation. Especially in line with the Party’s “One Belt One Road” policy agenda, China seeks to increase international cooperation in production capacity, stregthening national competitiveness in energy equipment exports.

Power Sector Reforms Announced in China’s 13th Five Year Plan

Nov. 7, 2016 China’s National Development & Reform Commission along with the National Energy Administration (NDRC and NEA) jointly released the “13th Five Year Plan for Power Sector Development” marking 15 years since the last time a Five Year Plan was released on the development of China’s power sector. The last Five Year Plan for the power sector was released January 1, of 2001, as part of the “10th Five Year Plan.”

The NDRC estimates by 2020, Chinese electric power consumption will reach 6,800 TWh of electricity, increasing on average by 3.6-4.8% each year. The per capita use is expected to reach approximately 5,000 kWh by 2020. (According to World Bank data from 2014, this is on par with the current per capita rates from nations like Greece, Spain, and the United Kingdom.) With China’s growing needs for power and a 15% renewables target in mind, the plan calls for the following goals to be met over the next five years. 

 

Hydropower

Add 40 GW hydropower capacity, with total installation reaching 340 GW by 2020.

Wind Power

Increase wind capacity by 79 GW, with total installed capacity of 210 GW by 2020, of which 5 GW will include offshore wind projects.

Solar

Add 68 GW of solar bringing total solar capacity to 110 GW by 2020, of which distributed solar will be 60 GW and thermal solar will be at 5 GW

Nuclear

Put 30 GW nuclear power into operation, reaching total capacity of 58 GW by 2020. Due to safety concerns, priority given to construction in coastal regions.

Biofuels

Reach 15 GW of biofuels production by 2020.

Natural Gas

Increase natural gas capacity by 50 GW, by 2020 total capacity will be over 110 GW, with CCHP-coupled technology occupying 15GW.

Coal

Cancel/delay construction of coal plants over 150 GW in scale, capping coal generation capacity at 1,100 GW by 2020. Upgrade 420 GW of existing equipment with low-emissions technology, modify 340 GW of equipment to increase energy efficiency, and phasing out over 20 GW of old equipment. By 2020 all coal plants must waste less than 310g/kWh of coal.  

System Upgrades

  • Promote a flexible electric system by increasing load shifting capabilities. Put into production 17 GW of pumped storage, bringing total pumped storage up to 40 GW.
  • In China's North, update 133 GW of capacity with thermoelectric technology and modify 82 GW of equipment with condensing units. Other locations will receive condensing unit upgrades totaling 4500 GW in capacity. After upgrades, the focus will be on increasing load-shifting capabilities by 46 GW, 45 GW in China's North. 
  • Increase transmission capacity by 130 GW to send power from west to east, bringing long-distance transmission capacity to 270 GW by 2020. 
  • Accelerate construction of electric vehicle charging stations, bringing total centralized charging stations over 12,000, and distributed charging stations over 4,800,000. Strengthen smart charging systems to satisfy the needs of China's expected 5,000,000 electric vehicles. 

System Reforms

  • Before the end of 2016, complete a electric power market mechanism. After which, power market trials will begin. 
  • Before the end of 2017, set electricity transmission and distribution prices
  • Ancillary services pilot for China's Northeast began in 2016, once the pilot has matured, an ancillary services market will be implemented nation-wide.
  • Before the end of 2018, establish spot market pilots, with nation-wide implementation by 2020.
  • Before 2020 cancel preferential rights for electricity generators. 
  • By the end of 2018, complete work to cultivate sell-side market competition mechanisms, encourage the launching of new electricity distribution services. 

While the specifics of implementation are left to subordinate government agencies, the power development reform document certainly gives a glimpse at how China's power sector will shape up in the upcoming five years. The renewables targets for solar and wind are considered disappointingly conservative by some advocacy groups, and create uncertainty about China's previously explosive growth in wind and solar power will continue to expand. Despite this, however, the announcement of power sector reforms establishing electric power market mechanisms, spot markets, and ancillary services markets still creates enormous potential for energy storage participation, as CNESA Secretary General, Tina Zhang, explains here and here.

Energy Storage Project Roundup

What exactly is happening in China? The world's highest elevation storage facility began operations, Chinese manufacturer GCL announced plans for a 500 MWh project, and what will be the world's largest Zn-Br flow battery components center was announced, to name a few. CNESA has prepared a roundup of some of China's latest energy storage projects that either came online or were announced this past month. 

Tibet Shuanghu County Renewable Energy Network (Now Operating)

Location: Shuanghu County, Tibet
Companies Involved: Owner: Power Construction Company of China – Northwest Engineering Storage providers: Corporation Clou Electronics Co., Sungrow Power
Key Specs: 13 MW solar PV station, 24 MWh battery storage system, 1.5 km of electricity lines and grid integration system.
Clou Electronics won 3 MW/10.08 MWh in tender for off-grid energy storage and container system (6 total containers) to provide frequency modulation and voltage control for the system. Sungrow Power will provide the entire 13 MW of PV inverters and header boxes, Samsung SDI-Sungrow will provide 7 MW of storage inverters and a 13.6 MWh Li-ion battery system.
Notes: The project, situated in Shuanghu County, Tibet, the world’s highest elevation administrative district, also represents the world’s highest elevation solar project. The project is part of an effort to power the region with a history of unstable electricity service, with residents relying largely on diesel generators and yak butter lamps, along with burning coal for heat during the cold winter months, resulting in negative health impacts on residents. The extreme elevation, high wind speeds, and adverse rain/snow conditions pose immense challenges for weatherizing the energy storage system equipment. Furthermore, the location only experiences an average 80 days per year without frost, thereby severely shortening the construction period.
