Source: National Energy Administration (NEA)

Recently, many regions across China have experienced hot and humid weather. Coupled with the dual driving forces of economic growth, power loads in various regions have risen rapidly. On July 4, the national maximum power load reached 1.465 billion kilowatts, an increase of approximately 200 million kilowatts from the end of June, setting a new historical high (compared to 1.451 billion kilowatts in 2024), and an increase of nearly 150 million kilowatts compared with the same period last year. Since the beginning of summer, the power grids in East China, eastern Inner Mongolia, Jiangsu, Anhui, Shandong, Henan, and Hubei have all reached historical highs.

At present, the national power supply remains generally stable and orderly. According to the China Meteorological Administration, from July 4 to 10, regions including Huanghuai, Jianghan, and Jiangnan will experience sustained high temperatures, with some areas reaching or exceeding historical extreme values for the same period. Power loads in East China and Central China are expected to continue rising, further driving nationwide power load growth. The National Energy Administration will closely monitor weather changes and the power supply-demand situation, guiding localities and power enterprises to ensure stable and full operation of generating units, coordinate inter-provincial and inter-regional power balance, promptly resolve emerging issues, and make every effort to ensure electricity supply for people to stay cool during the summer, fully supporting high-quality economic and social development.

93 Energy Storage Stations Participate! Jiangsu Completes China’s Largest Centralized Dispatch of New Energy Storage

According to State Grid, due to the ongoing high temperatures, as of July 7, Jiangsu’s power grid load has broken historical records for the third time this year, reaching 152 million kilowatts. On July 6, under the unified command of the Power Dispatch and Control Center of State Grid Jiangsu Electric Power Co., Ltd., a total of 93 new-type energy storage stations across the province discharged electricity to the grid during the evening peak, with a maximum discharge power of 7.14 million kilowatts, achieving the largest centralized dispatch of new-type energy storage in China.

New-type energy storage is known as a “super power bank,” capable of discharging power during peak demand periods for peak regulation, and charging during off-peak periods to aid the consumption of new energy.

On the evening of the 6th, to support the evening peak of grid electricity usage, a total of 64 grid-side and 29 power-side energy storage stations participated in the centralized discharge. The total participating capacity reached 7.248 million kilowatts, and the actual maximum dispatch scale was 7.14 million kilowatts. This set a new record in centralized dispatch scale, marking a 56.9% year-on-year increase compared to the centralized dispatch of 4.55 million kilowatts of new-type energy storage last summer.

In this centralized dispatch of new-type energy storage, State Grid Jiangsu Electric Power issued discharge instructions to more than 7 million kilowatts of new-type energy storage through its next-generation dispatch support system during peak demand, with a maximum capacity sufficient to meet the one-hour electricity needs of approximately 48 million households.

While it may appear simple, the timing of charging and discharging must be carefully chosen. Discharging, while considering urban electricity demand, must also strive to enable energy storage projects to generate revenue. “Spatially, most of Jiangsu’s energy storage projects are located in northern Jiangsu, while electricity demand is concentrated in southern Jiangsu. The electricity peak in southern Jiangsu occurs during the day, while in northern Jiangsu it occurs at night. Therefore, energy storage can act as a ‘spatiotemporal regulator,’” explained Qiu Chenguang, Director of Dispatch Operation at the Dispatch and Control Center of State Grid Jiangsu Electric Power. Jiangsu’s current installed capacity of new-type energy storage is 7.616 million kilowatts, ranking fourth nationwide, and includes various forms such as electrochemical energy storage and salt cavern compressed air energy storage.

As the first utility-scale large energy storage project in North Africa, it is expected to reduce CO₂ emissions by over 150,000 tons annually and provide stable electricity for approximately 500,000 households. The project effectively supports Egypt in increasing the proportion of renewable energy, accelerates the implementation of the “2030 Sustainable Energy Strategy,” offers a “Chinese solution” for PV-storage integration in Africa, and provides strong support for comprehensively enhancing the core competitiveness of the “Four New” areas and expanding the African new energy market.

Brazil’s First Energy Storage Regulatory Framework to Be Introduced This Year, Covering Revenue Mechanisms

At a public hearing held by the Chamber of Deputies’ Mines and Energy Committee, Daniel Danna, Director of the National Electric Energy Agency (ANEEL), stated that the regulatory authority intends to introduce the country’s first regulatory framework for energy storage this year. These initial standards will cover grid access and usage, as well as revenue mechanisms for energy storage, including revenue stacking models.

Danna stated that, at this stage, the regulatory impact analysis and the proposed normative resolution have been completed, and approval is scheduled for the second half of this year. The framework will also address future scenarios such as grid capacity auctions and isolated-system auctions.

Following approval of the results of Public Consultation No. 39 (CP 39), the second round of discussions will focus on the regulatory treatment of “reversible” power plants, criteria for recognizing storage facilities as transmission and distribution system assets, and the regulatory framework for storage systems used to mitigate curtailment and power rationing. A planned third round of discussions will focus on the “storage-as-a-service” aggregator and system operation simulation studies, with all discussions expected to conclude by 2028.

It is understood that CP 39 (Consulta Pública nº 39/2022) was a special public consultation document launched by ANEEL in 2022 concerning the regulatory framework for energy storage systems.

At the hearing, Danna specifically pointed out the impact of budget cuts at the regulatory agency on the progress of discussions regarding energy storage rules.

The hearing also focused on the growing demand for energy storage driven by the surge in renewable energy such as solar PV and wind power. The rapid increase in these sources has outpaced electricity demand and transmission capacity, resulting in widespread curtailment and posing operational challenges for the National Electric System Operator (ONS), particularly the mismatch between midday solar generation peaks and nighttime demand peaks. Brazil’s 103 GW of hydropower installed capacity—accounting for more than half of the country’s energy mix—struggles to adapt to the rapid fluctuations in renewable output and grid load.

Christiany Salgado Faria, Director of Planning and Grants for Electric Power Generation at the Ministry of Mines and Energy (MME), emphasized that the Plano Decenal de Expansão de Energia 2034 projects the need for an additional 5.5 GW of peaking capacity by 2028 to meet system needs. By 2034, this figure is expected to exceed 35 GW.

Between 2024 and 2034, the share of hydropower in Brazil’s energy mix is projected to fall by 10 percentage points to 36%. The share of renewable energy will continue to rise, with distributed clean energy (mainly PV) increasing from 13% to 18%, and centralized solar and wind power rising from 21% to 24%.

Salgado Faria stated that it is therefore necessary to advance the energy storage discussion to address the issue of system flexibility. Currently, public policy is focused on storage auctions, and the Ministry of Mines and Energy has launched a public consultation (CP 176/2024) on related guidelines, but the final plan is still under discussion.

According to the consultation document, energy storage auction contracts will have a ten-year term, starting on July 1, 2029. The projects must provide four hours of daily discharge service under ONS dispatch, and revenues will be adjusted based on the Índice Nacional de Preços ao Consumidor Amplo.

Rodrigo Sauaia, President of the Brazilian Association of Photovoltaic Solar Energy, expressed concern about the postponement of battery storage participation in capacity reserve auctions. He stated: “We recently saw a legal dispute that delayed the auction of thermoelectric and hydroelectric capacity reserves. And our concern is that the batteries not be left for later because we have seen some talk that the battery auction will only take place after the thermoelectric and hydroelectric auction. Why, if this technology is already mature and ready to be used?” Rodrigo Sauaia called for the immediate implementation of battery auctions. This would be a major milestone for Brazil during the year of the COP30 summit—holding the country’s first-ever battery auction and demonstrating Brazil’s commitment to applying this technology.

Major Breakthrough in Spain’s Energy Storage Policy: Energy Storage Explicitly Classified as “Public Utility”

The Spanish government approved Royal Decree 7/2025 on June 24, resolving several long-standing obstacles hindering the secure and lawful deployment of energy storage projects. This move responds to the large-scale blackout incident experienced by the country in April this year. The Spanish Battery Energy Storage Association (AEPIBAL) stated that the new regulation marks a major breakthrough for energy storage development in Spain.

To accelerate energy storage industry growth, the decree stipulates: Energy storage facilities located within the scope of renewable energy power stations that have passed environmental impact assessments are exempt from environmental evaluation procedures. This measure addresses long-standing industry demands and is expected to significantly shorten project approval cycles.

The decree explicitly classifies energy storage facilities and their associated grid connection infrastructure as “public utility” for the first time. This grants them legal support equivalent to power generation facilities in land acquisition and permitting processes, marking a major breakthrough in Spain’s energy storage policy.

The new regulation finally implements the following core elements promoted for years by AEPIBAL and the Ministry of Energy:
• The Declaration of Public Utility (DUP) is formally established for energy storage facilities and their associated infrastructure—used for injecting and withdrawing electricity between transmission and distribution networks—mirroring the existing legal status of power generation facilities. "Declaration of Public Utility" means the government recognizes such projects as serving public interest, granting rights to legally acquire land and simplify approval procedures.

• For hybrid power generation projects with battery storage, approval processes will be substantially streamlined provided the energy storage facilities are within the project’s planned boundaries. Crucially, such projects are exempt from environmental impact assessments.

• "Installed capacity" is explicitly defined as the maximum output power of inverters. This adjustment fundamentally changes the approval authority threshold for hybrid projects (＞50 MW projects require central government approval; ≤50 MW projects require local government approval). Henceforth, capacity calculations for hybrid project components will no longer be cumulative.

• A breakthrough is achieved in the key area of contention between the Ministry of Energy and the National Markets and Competition Commission (CNMC)—new rules abolish discriminatory treatment of hybrid generation projects under technical curtailment orders. Per the updated regulation, all renewable energy power stations (regardless of energy storage configuration) will receive priority protection during grid congestion, becoming the last to be curtailed.

• Another major breakthrough: Energy storage facilities will gain demand-side flexible access permits and will no longer be classified as electricity consumers. Simultaneously, the regulation standardizes grid connection guarantee requirements: relevant matters are now exclusively handled by project file management agencies, and guarantee releases will only be tied to generation warranties, decoupled from supply contracts.

• Finally, for Behind-the-Meter (BTM) energy storage, the regulation explicitly defines the functions of independent aggregators for the first time—this innovative institutional arrangement requires further specialized discussion and refinement.

It must be specifically noted that this Royal Decree (RDL) has a 30-day provisional validity period. It must obtain approval from the Congress of Deputies within this timeframe to be permanently incorporated into the legal system. If parliamentary approval fails, all provisions of the decree will automatically lapse, at which point the original regulatory framework will be reinstated.

On April 28 this year, Spain experienced a widespread blackout. According to the Spanish Ministry of Energy, grid power supply dropped by approximately 60% within five seconds, equivalent to 15 GW. Portugal, interconnected with Spain’s grid, also suffered extensive power outages. Both countries faced transportation paralysis, communication blackouts, and public life descended into chaos. Electricity supply was largely restored the following day. This stands as one of Europe’s most severe power failure incidents in recent years.

On June 17, the Spanish government released a report attributing the root cause of the blackout to an instantaneous voltage spike—a voltage surge. However, Spain’s power system exhibited "insufficient voltage control capability," stemming from inadequate planning and ineffective response. Due to misjudgment, the surge was not promptly absorbed, triggering a series of "uncontrollable chain reactions." Theoretically, Spain’s grid was robust enough to handle such situations, but the entire system lacked coordination, transparency, and clear division of responsibilities. The government believes enhanced regulation of power operators and grid reinforcement are necessary moving forward.

India Launches 4GWh Solar-Storage Project Tender! Opportunities and Strategies for Chinese Enterprises Under New Mandatory Storage Policy

According to foreign media reports on June 16, the Solar Energy Corporation of India (SECI) has launched a tender for 2GW of grid-connected solar projects, coupled with 1GW/4GWh of energy storage systems. Projects will adopt the "Build-Own-Operate" (BOO) model and can be constructed anywhere in India.

Key terms:

Storage ratio: For every 1MW of solar capacity contracted, developers must configure at least 500kW/2MWh of storage capacity. Storage facilities may be self-owned by developers or secured through third-party agreements to guarantee power supply.

Power Purchase Agreement: SECI will sign a 25-year Power Purchase Agreement (PPA) with winning bidders.

Bid scale: Individual solar project developers must bid for a minimum of 50MW and a maximum of 1GW, with increments in multiples of 10MW.

Supply requirements: Developers must deliver 2MWh of AC electricity per MW of rated capacity daily during grid peak hours specified by the power purchaser (e.g., a 100MW project must supply 200MWh during peak periods).

New Indian Power Ministry Policy: Mandatory Storage for Solar Projects

Earlier this year, India’s Power Ministry issued regulations requiring all relevant renewable energy implementing agencies and state power companies to equip solar projects with energy storage systems at a ratio of 10%/2h during tenders.

The regulation aims to address solar power intermittency and provide support during peak electricity demand periods. Distribution companies may also consider introducing 2h storage systems in rooftop solar installations.

The Power Ministry noted that falling battery costs could further reduce solar curtailment and save on expensive nighttime power purchases.

Under this policy, the Indian government expects to add approximately 14GW/28GWh of energy storage capacity by 2030. India’s renewable energy tenders surged in 2024, with nearly 70GW tendered and 40GW allocated. Nearly half of these tenders were for solar projects. With this new regulation, future tenders will integrate storage systems alongside solar projects.

As of December 31, 2024, India’s total installed energy storage capacity stands at 4.86GW, including 4.75GW from pumped hydro and 0.11GW from new energy storage projects.

Business Model Innovation Accelerates Storage Deployment

India aims to achieve energy independence by 2047 and net-zero emissions by 2070, with battery storage playing a critical role. Consequently, India has introduced a series of storage policies, including defining the legal status of energy storage systems, proposing a Viability Gap Funding (VGF) scheme, exempting storage systems from transmission and distribution charges, replacing diesel generators with storage backup systems, and integrating storage into the High-Price Day-Ahead Market (HP-DAM).

Innovative business models such as “Battery-as-a-Service” (BaaS) and “Storage-as-a-Service” (SaaS) are emerging. BaaS allows companies to lease storage equipment without upfront investment, paying usage fees while service providers handle maintenance and management. SaaS offers similar flexibility, enabling businesses to pay only for consumed storage capacity. These models lower entry barriers and provide scalable, sustainable solutions for commercial and industrial users. Current revenue streams for front-of-meter storage in India include ancillary services, energy arbitrage, long-term PPAs bundled with renewables, demand-side response, and storage services.

Under SECI’s February 2025 energy storage tender, developers can receive 30% funding or ₹2,700/kWh subsidy via the VGF mechanism, whichever is lower. To encourage early commissioning, projects completed ahead of schedule qualify for a 12% investment incentive and may sell capacity to third parties in advance, subject to SECI approval.

India’s Solar Potential Reassessed at 10.8TW

A new study by The Energy and Resources Institute (TERI) reveals India’s total solar potential reaches 10,830GW—a magnitude higher than the Ministry of New and Renewable Energy’s (MNRE) 2014 estimate of 748GW. The study not only recalculates traditional deployment areas like wasteland but also explores multidimensional development pathways.

Sector-Specific Potential Breakdown:

• Wasteland-based ground-mounted solar: 4,909GW (45% of total)

• Floating solar: 100GW (based on 2.5% coverage of artificial water bodies)

• Urban and rural rooftop solar: 960GW (calculated at 9m²/household in rural areas; 10m²/household in urban areas)

• Agrivoltaics: 4,177GW (suitable for horticulture, tea gardens, etc.)

• Transport infrastructure and building-integrated PV: 684GW (including railways/highways, BIPV)

By comparison, MNRE’s 2014 estimate of 748GW solar potential relied solely on 3% wasteland utilization. TERI’s updated data coincides with a critical phase in India’s energy transition—as the nation updates its Nationally Determined Contributions (NDCs) under the Paris Agreement and pursues its 2070 net-zero emissions goal, it is comprehensively upgrading its clean energy development plans.

Under India’s revised 2022 NDCs, the country commits to reducing emissions intensity by 45% from 2005 levels by 2030 while ensuring non-fossil energy accounts for 50% of installed capacity. TERI projects India’s electricity demand will surge to 9,362TWh by 2070, underscoring solar power’s irreplaceable role in deep decarbonization of the power sector.
