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.

Upon completion, the project will substantially enhance local renewable energy output stability and grid regulation capabilities. It will further solidify Narada’s leadership in the global advanced energy storage sector and positively impact the company’s future operational performance.

Globally, Narada’s liquid-cooled energy storage systems have demonstrated exceptional reliability and high availability across multiple operational projects. They meet long-duration, high-intensity application demands, accelerating the global energy transition.

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:

Europe's Worst Blackout in Years! Just 6 Days After Grid Ran on 100% Renewables

According to a CCTV News report on April 29, Spain and Portugal experienced a massive power outage on the 28th, affecting over 50 million people across the Iberian Peninsula. Critical services—including transportation, communications, and healthcare—were temporarily paralyzed, with brief disruptions also reported in southern France and neighboring regions.

European Commission Executive Vice President Teresa Ribera stated that there is currently no evidence linking the blackout to a cyberattack. The incident ranks among Europe’s most severe power failures in recent years.

Authorities have yet to confirm the official cause, with investigations ongoing.

Eduardo Prieto, head of Spanish grid operator Red Eléctrica, said on April 28 that the outage was triggered by a "violent oscillation in the grid," which disconnected Spain’s power system from the European network. This aligns with Prime Minister Pedro Sánchez’s reference to a "major technical fluctuation."

Grid oscillations—often caused by rapid shifts in power generation or demand—can lead to cascading failures. For instance, sudden large-scale load changes disrupt the balance between supply and consumption, destabilizing the system.

Portuguese grid operator REN suggested the abnormal oscillation may be linked to extreme temperature swings in Spain. Experts noted that such fluctuations can destabilize ultra-high-voltage networks above 400 kV.

Renewable energy’s role is also under scrutiny. Data from Red Eléctrica shows renewables accounted for 56% of Spain’s electricity in 2024. Just days earlier, on April 16, 2025, the country’s grid achieved a historic milestone by operating entirely on renewables (wind, solar, and hydro) for a full day. The blackout has reignited debates about grid stability amid rising renewable penetration. Europe’s power systems increasingly face challenges in balancing supply and demand, with large-scale renewable integration raising oscillation risks.

The Iberian grid—highly interconnected but linked to Europe via limited cross-border lines—exposed the vulnerabilities of energy isolation. While Ribera ruled out cyberattacks, the event underscores Europe’s struggle to adapt to renewable volatility.

Analysts urge accelerated grid modernization and cross-border capacity upgrades to tackle renewable intermittency and extreme weather. The blackout may prompt the EU to fast-track energy security reforms and enhance grid resilience.

Energy analysts note that outages of this scale are rare in wealthy nations. Given Iberia’s heavy renewable reliance, the incident will serve as a “case study on renewables’ reliability and post-blackout recovery.”

UK Media: Surging Demand in Grid Energy Storage Market Opens New Front in China-South Korea Battery Rivalry

"Chinese and Korean firms are extending their battery battle from EVs to grid storage”, reported the Financial Times on April 28th. The surging global demand for renewable energy and data centers is driving rapid growth in the grid-scale battery storage market, creating a new battleground for Chinese and Korean battery giants—who have already been locked in fierce competition in the EV battery sector.

The report noted that Chinese battery manufacturers now account for nearly 90% of global energy storage system (ESS) production capacity, holding over 80% and 75% market shares in the U.S. and Europe, respectively. However, with rising U.S. tariffs, Korean firms are seeking to regain ground in Western markets.

Energy storage systems use battery modules managed by software to help grids—as well as homes, businesses, and factories—handle fluctuations in wind and solar power supply. For the next decade, as electricity demand surges from AI hardware, EVs, and other clean technologies, ESS will also provide critical backup support for power grids.

A International Energy Agency (IEA) report of this month predicts that global electricity demand from AI data centers will double in the next five years, accounting for nearly half of U.S. power demand growth by 2030."Energy storage is often seen as the least glamorous part of renewables, but it’s actually the core technology ensuring grid stability in the future." said Iola Hughes, research director at battery consultancy Rho Motion.

According to Statistics from Rho Motion, ESS batteries’ market share has risen from 5% in 2020 to 20% today. Global storage capacity grew 52% between 2023 and 2024 and is projected to jump from 340 gigawatt-hours (GWh) last year to 760 GWh by 2030—equivalent to 7.6 million EV batteries. The booming market has even helped Tesla offset sluggish EV sales, with soaring demand for its Powerwall home batteries and Megapack grid-scale storage systems. CEO Elon Musk described the business as "spreading like wildfire."

Hughes told the FT that Korean battery makers once led the industry with their high-nickel batteries. However, a series of fires linked to these batteries over the past decade—combined with the rise of cheaper, increasingly efficient lithium iron phosphate (LFP) batteries—has led the energy sector to shift away from high-nickel chemistries. "The diverging fortunes of Chinese and Korean storage firms tell the story of two battery markets," said Neil Beveridge, head of energy research at Bernstein in Hong Kong.

China’s dominance in energy storage has raised concerns among Western policymakers, with the U.S. banning Chinese battery systems in military facilities. This has given hope to Korean firms transitioning to LFP production—or even repurposing EV battery lines. LG Energy Solution, the world’s largest non-Chinese battery producer, said tariffs make "non-Chinese companies with U.S. production bases more competitive."

Data from the Atlantic Council shows that China exported $15.3 billion worth of lithium-ion batteries to the U.S. last year, widening its lead over Korean rivals. "Chinese LFP batteries are popular in the U.S. due to their price competitiveness. Plus, they can use more battery cells, making them cost-effective for data centers," said an industry insider.

UBS analyst Tim Bush noted that while Korean firms like LG and Samsung SDI may gain "a bigger share of a smaller market" due to tariffs, their mass-production capabilities and cost competitiveness in LFP batteries remain unproven. The future landscape is still highly uncertain.

Narada Initiates Hong Kong IPO Process, Accelerating Global Expansion

Narada has officially commenced its Hong Kong IPO, marking a significant stride toward becoming a dual-listed (A+H) global industry leader.

As an international financial hub, Hong Kong offers access to global capital and resources. Narada’s decision to pursue a Hong Kong listing carries profound strategic significance—not only as a breakthrough in capital operations but also as a pivotal step toward global expansion and leapfrog development.

The Hong Kong listing will further advance the company’s globalization strategy, elevate its brand profile and visibility, and enhance overall competitiveness. Simultaneously, it will establish an international capital operations platform, improving corporate governance transparency and standardization.

With over two decades of commitment to globalization, Narada’s energy storage business now spans 160 countries and regions. The company has established localized sales and service centers across Europe, North America, Australia, Japan & South Korea, the Middle East, and other key markets, enabling end-to-end support for global energy storage project deployment.

In expanding its overseas footprint, Narada has deepened vertical and horizontal industry collaboration, building multidimensional competitive advantages in technology, capital, and partnerships. The company has forged strong ties with international energy groups, design institutes, EPC firms, financial institutions, and supply chain partners worldwide.

The primary objectives of this Hong Kong IPO are threefold: deepening overseas market penetration, expanding international business operations, and strengthening global working capital reserves. With the dual engines of capital empowerment and technological innovation, Narada will maintain its leadership in driving the energy storage revolution while contributing China's solutions to achieving global carbon neutrality goals.
