At present, Narada has entered storage agreements totaling over 2.1 GWh (including the 200 MWh above), with 120 MWh already in operations. According to Chinese Battery Enterprise Alliance, Narada has already set aside CNY2 billion (US$300 million) in funds for battery projects. In the first half of 2017, Narada has already collected CNY133 million (US$20 million) in sales revenue, of which energy storage projects have accounted for CNY79 million (US$11 million) in sales.

The announced projects total CNY260 million (US$38 million) in investments from Narada, and upon completion expect to have a massive impact on future earnings.

Data: CNESA project database, CNESA White Paper 2017.

CNESA Alliance member Narada Power, a Hangzhou-based company founded in 1994, specializes in high-performance lead-based batteries for use in telecom, electric power systems, infrastructure, and renewable energy applications. According to data published in CNESA's 2017 White Paper, Narada currently ranks 6th in China’s top 10 storage providers in terms of kW of storage in operation (2016 data). While the top providers are dominated by Li-ion manufacturers, the Sacred Sun (no. 2) also specializes in lead based batteries. With improved battery technology and performance, lead batteries have maintained a cost advantage over Li-ion alternatives, and today represent 31% of China’s total installed electrochemical storage capacity.

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.

Kehua Technology Large Scale Off-Grid PV Storage Project (Now Operating)

Location:	An oil field in Uzbekistan
Companies Involved:	Kehua Technology Co.
Key Specs:	1.2 MW distributed solar PV, 1 MWh lead acid colloid battery system
	Design includes inverters, battery container boxes, power distribution equipment. Principal functions: electricity generation and distribution, with Kehua providing system controls.
Notes:	System operations are divided into three modes:
	1) Solar generation ≥ load requirements: solar PV cells will provide electricity and diesel generators will stop running. The off-grid inverters will convert the solar electricity for use in the oil field and will charge onsite storage batteries.
	2) Solar generation < load requirements: [Stage 1]; solar cells and battery storage will provide electricity together. [Stage 2]; When battery charge is low, this will initiate diesel generators to begin providing the oil field with power, solar energy will be used instead for battery charging.
	3) No solar generation and insufficient battery charge: diesel generators provide the oil field with electricity without charging batteries. This guarantees that the critical equipment in the oil field can safely and stably continue operations.

GCL's E-KwBe currently comes in multiple colors of 2.5 kWh and 5.6 kWh models.

GCL has called itself the “One-stop solution for comprehensive energy integration.” With its E-KwBe Li-ion battery model is hailed by many as the biggest threat to Tesla’s PowerWall battery systems (and cheaper too), their motto might be more than just marketing puffery. The Chinese manufacturer recently reached an agreement with the Australian wholesaler One Stop Warehouse to distribute another 1,000 E-KwBe units in October. The first batch of 1,000 units was already successfully delivered to Brisbane in September. Currently E-KwBe comes in 2.5 kWh and 5.6 kWh models. New documents show the company is also in preparations for developing a 500 MWh battery storage project. GCL recently raised nearly US$500 million in capital, of which it will siphon US$14.5 million into the the 500 MWh project. Total project investment for the 500 MWh project is estimated to be US$26 million, and is expected to take a year to complete.

Zhuhai City Intensifies Electricity System Reforms

A wind turbine overlooks fields in Hengqin New Area, Guangdong Province.

The city of Zhuhai, Guangdong Province is known for its proximity to the Macau Special Administrative Region, much like Shenzhen is positioned relative to Hong Kong. Like Shenzhen, Zhuhai is also a site of many innovative economic experiments and reforms, most recently with the government announcing plans to implement pilot projects geared at buy-side reforms to its electricity system. The city will explore ways to employ efficient business models, giving local enterprises in several designated special economic zones more autonomy in managing grids and utilities. Projects in Hengqin New Area and Xibu Ecological Zone will give enterprises the right to operate smart microgids and sell their own electricity. Additionally the city has plans to use thermal energy generated in Hengqin to provide electricity for Doumen New Green Industrial Park, while East Jinwan District will rely on natural gas distributed generation to power smart girds. Based on market conditions, the city also plans to incrementally invest in electric services industries.

The city government will grant enterprises located in these advanced technology parks and economic zones the authority to manage microgrids and provide their own water, gas, and heating. Electricity generating enterprises can create their own marketing bodies within a defined scope, which can, over time, begin to resemble the structure of electric utility companies possessing rights to operate the grid. It is important to note, however, that these pilot enterprises, are limited in scope at the discretion of the governing body and are not permitted to establish “multi-layered bodies” to sell electricity in the marketplace. 

Total implementation of a buy-side distributed generation market appears to be quickly accelerating towards Doumen District and the distributed energy projects in Jinwan District. The pilot projects implemented will encourage industrial parks, commercial zones, and other newly created districts to implement natural gas distributed energy systems, and even in some other applicable cases, encourage distributed PV generation networks. Allowing distributed generation to enter the grid will encourage specialized energy providers to work with consumers ushering in a new model of “cooperative energy management.”

Renewable Integration Update: Northwest China

In the first half of 2016, newly installed wind plants in China’s northwestern provinces (Shaanxi, Gansu, Qinghai, Ningxia, and Xingjiang) increased total grid capacity by 401 MW. At the end of June, 2016, the total accumulated energy from wind contributed 37.428 GW to the grid, making up 18.7% of total grid capacity. Additionally, in the first half of 2016, wind power generated 24.4 TWh of energy, representing 8.2% of energy generated by the grid. Of this, only 688 hours of energy were consumed, meaning 15.53 TWh was wasted, bringing the curtailment rate to 38.9%. Gansu, Xinjiang, and Ningxia ran up the most severe curtailment rates of 46.6%, 44.2%, and 20.9% respectively. Shaanxi province, on the other had had curtailment rates of only 3.0% and Qinghai province has yet to observe any curtailment.

In terms of solar PV, new installations in the Northwest added 1.787 GW to overall grid capacity, bringing the accumulated total to 21.942 GW installed solar PV capacity, composing 11.0% of grid capacity. Electric power generated from solar PV was 13.38 TWh, representing 4.5% of all grid energy generated. Of this, 611 hours were consumed, meaning 3.28 TWh were wasted, with a total curtailment rate of 19.7%. The highest rates of curtailment came from Xinjiang and Gansu province with rates of 32.4% and 32.1% respectively. Ningxia’s curtailment rate was 10.9%, Qinghai’s 3.2%, and Shaanxi, recorded its first instance of solar curtailment at 1.7%.

CNESA Successfully Co-Launches Training Course “Distributed Generation and Microgrids”

Shutterstock/robuart

Last month on June 14, 2016, CNESA, in partnership with North China Electric Power University, jointly launched a training course titled “Distributed Generation and Microgrids.”Chief specialist at the China Electric Power Research Institute, Xuehao Hu, conducted the session. All 19 members of CNESA’s secretariat were in attendance.

Hu began the lecture by introducing the background of distributed generation, its fundamental features, types of distributed generation networks, its prominent role in the energy sphere, as well as how China’s current technology compares to international developments in the field. It is currently estimated that by 2020, distributed generation will make up approximately 9% of all electricity generated in China (excluding small-scale hydropower, this number is closer to 5%), making distributed generation an important part of China’s electric generation system.

Hu continued by introducing the interconnected issues of distributed generation and the grid. Connecting distributed energy sources to the grid poses many challenges. First, there are design problems in the traditional grid as well as connectivity issues. Energy generated by renewable sources also, by its very nature, is intermittent and relatively unpredictable. Furthermore, the economics of grid planning poses a whole new set of challenges.

Next, Hu presented a detailed discussion on how China should formulate its own set of standards on distributed generation. While it is important to refer to already established European and American standards, Hu argues China must also consider the different circumstances in its own energy landscape. Thus, he concluded, Chinese standards can draw inspiration from, but cannot entirely resemble those of the U.S., Europe, and other developed nations.

Regarding microgrids, Hu highlighted the principal difficulties and key technologies associated with microgrids. Compared to distributed generation networks, microgrids have been in development for a relatively short time. Consequently future construction and design efforts must give sufficient consideration to technological concerns, economics, as well as natural variables in the environment (i.e. temperature, availability of light, sun, air, etc.) Careful design of microgrids, Hu argues, is how we can keep costs low and reap the largest benefits.

To make his final point, Hu pointed out that distributed generation and microgirds in the form of solar power are, in fact, already widespread in China’s poorest regions. Hu hopes that advances in distributed generation and microgrids can and build off of and deepen these existing networks.

With the successful completion of this first training course, CNESA will continue to strive to integrate resources from government, scientific experts, and private industry in order to provide alliance members with the highest quality content and services.
