July 21, 2015 - China Expands Renewable Energy Infrastructure Projects

On July 21, 2015, you're watching China place a bet that'll reshape global renewable energy — the National Energy Administration's solar thermal request for proposals didn't just open a bidding process; it unleashed a 4 GW land rush that signaled Beijing's intent to dominate concentrated solar power the same way it had already conquered wind and photovoltaics. What followed — the projects, the technology battles, and the policy shifts — tells a much bigger story.

Key Takeaways

• China's National Energy Administration released a solar thermal request for proposals in September 2015, attracting roughly 50 project applications totaling 4 GW.
• A feed-in tariff of 1.2 RMB/kWh was approved, unlocking private investment and fundamentally transforming the scale of China's solar thermal industry.
• Policy incentives from NDRC and NEA directed investment toward resource-rich western regions, including Xinjiang, Qinghai, Gansu, and Inner Mongolia.
• China's 12th Five-Year Plan set a 1 GW solar thermal target for 2015, rising to 3 GW by 2020, though actual deployment lagged.
• SUPCON's Delingha project secured China's first CSP feed-in tariff, signaling strong government commitment to expanding renewable energy infrastructure.

How China's 2015 Solar Thermal RFP Triggered a 4 GW Land Rush

When China's National Energy Administration released its solar thermal request for proposals in September 2015, it set off a scramble that few had anticipated.

You're looking at roughly 50 project applications totaling 4 GW of capacity submitted before the October 31 deadline. State-owned giants like China General Nuclear and China Huaneng Group competed alongside private firms and foreign players like Abengoa and BrightSource.

Land acquisition became a critical early battleground, as solar-rich regions offered local policy support to attract developers. Regions such as southern Tibet and Golmud in Qinghai proved especially attractive given that they record the most solar radiation in the country.

Financing mechanisms gained urgency too, particularly after SUPCON's Delingha project secured China's first CSP feed-in tariff at 1.2 yuan/kWh, signaling government commitment. That single tariff approval unlocked private investment and transformed what was once a 17 MW industry into a nationally prioritized energy sector. Underpinning this ambition was China's 3 GW solar thermal target for 2020, which gave developers and policymakers a concrete horizon to build toward. Much like how GSM standardization slashed manufacturing costs and accelerated deployment across competing operators in the telecom sector, a unified policy framework in China's solar thermal industry helped eliminate fragmentation and drive rapid infrastructure expansion.

Why Western China Became the Epicenter of CSP Development?

Because western China combines extreme solar intensity with vast uninhabited terrain, it's emerged as the natural home for the country's concentrating solar power ambitions. Provinces like Xinjiang, Qinghai, Gansu, and Inner Mongolia deliver high direct normal irradiance that CSP systems require to perform efficiently.

You'll find that desert logistics, while challenging, actually favor large-scale CSP deployment since open land eliminates costly site preparation and land acquisition disputes. Policy incentives from the NDRC and NEA reinforce geographic advantages, directing investment and project approvals toward these regions.

Turpan City already hosts a 100 MW molten salt tower plant, and Shanshan County features a 1 GW solar thermal and PV integrated project. Western China's HVDC connections then move that dispatchable power directly to eastern demand centers. The national pipeline across these western provinces now exceeds 8 GW of CSP capacity under various stages of development.

China's government adopted Spanish-style feed-in tariffs to nurture a domestic CSP supply chain and accelerate project development across these resource-rich western regions. Similar to how Airbnb prioritized trust over short-term revenue during COVID-19 to build long-term platform stability, China's sustained policy commitments in western regions signal that renewable energy development depends on institutional confidence rather than immediate economic returns.

Who Was Competing for China's First Solar Thermal Contracts?

China's push into concentrated solar power brought a diverse field of competitors vying for its first solar thermal contracts, spanning both domestic heavyweights and international technology leaders.

You'd find state-owned enterprises like China Longyuan Power and Datang Corporation positioning themselves aggressively alongside private developers.

Foreign bidders weren't standing aside either—companies from Spain, the United States, and Israel pursued technology partnerships with Chinese firms to strengthen their bids.

These collaborations let international CSP specialists combine their proven expertise with local partners' regulatory familiarity and financing access.

China's government structured the bidding process to encourage this knowledge transfer, ensuring domestic industries absorbed critical technical capabilities.

The result was an intensely competitive field where technology partnerships became the decisive factor separating serious contenders from peripheral players. Among U.S.-linked solar players, First Solar distinguished itself through its proprietary CdTe thin-film technology, setting it apart from the crystalline silicon manufacturers dominating most competitive bids.

Meanwhile, the broader solar manufacturing landscape reflected deepening financial strain, with leading Chinese module producers LONGi, Jinko Solar, Trina Solar, and JA Solar recording combined net losses of RMB11 billion in the first half of 2025.

How China's CSP Capacity Targets Kept Growing?

As China's CSP ambitions took shape, its capacity targets kept scaling upward with each successive planning cycle. Under the 12th Five-Year Plan, you'd see a modest 1GW target set for 2015, rising to 3GW by 2020. But actual progress lagged far behind, revealing a significant gap between policy shifts and real deployment. Japan similarly demonstrated that ambitious energy infrastructure goals can outpace deployment when regulatory and spectrum constraints slow the pace of practical implementation.

The 13th Five-Year Plan then triggered dramatic target escalation, pushing the 2020 goal to 10GW — a figure requiring 700 times the capacity China held in 2014. That ambitious leap was widely deemed unlikely given the short timeframe. To help bridge the gap between targets and actual deployment, China's NDRC established a feed-in tariff of 1.2 RMB/kWh to incentivize early commercial CSP projects.

Looking further ahead, China's most recent planning framework sets an even more ambitious benchmark, targeting ~15 GW total installed CSP capacity by 2030, alongside a goal for CSP generation costs to reach parity with coal-fired power by that same year.

What Made Molten Salt Storage Central to Every Project?

Molten salt storage didn't just complement China's CSP projects — it became their backbone. You'll find it at the center of every major deployment because it solves problems other technologies can't. Its thermal decoupling capability separates heat production from electricity generation, eliminating load regulation conflicts in thermal power units. Salts operating between 190°C and 565°C retain heat for hours after sunset, keeping steam flowing when sunlight stops.

At scale, the advantages multiply. The Jinta project's 2,000MWht system spans 10 hectares and anchors a full wind-solar-storage-heat network. Industrial integration happens naturally — over 40 enterprises receive stable heat supply, cutting 32,000 tons of coal consumption annually. With no tank leaks recorded across Chinese CSP sites, molten salt storage earned its central role through consistent, measurable performance. Three 25MW molten salt electric heaters work alongside the storage system to ensure continuous and precise thermal output across varying load conditions.

Projects like the Suzhou Thermal Power Plant demonstrate how molten salt systems can deliver 85,000 tons annual carbon reductions while simultaneously enhancing grid flexibility and supporting coal-fired units in transitioning toward regulation-oriented roles. Much like Java's write-once-run-anywhere design allowed a single software solution to operate across vastly different hardware environments, molten salt storage offers a unified thermal solution adaptable across diverse grid and industrial configurations.

Why the Delingha Plant Set the Benchmark for Chinese CSP?

When the Delingha plant crossed 100% of its 146 GWh design target for three consecutive years, it didn't just meet expectations — it redefined them.

You're looking at the only global tower molten salt CSP plant averaging above 100% annually across that stretch, generating 152.4 GWh in 2023 alone.

Its operational resilience shows in four-and-a-half years of steady output, with repeated records in daily, monthly, and annual performance categories.

Thermal benchmarking from Germany's Fichtner confirmed it's state-of-the-art globally among comparable technologies.

Engineers boosted mirror-field flow rates, optimized temperature-control logic, and replaced key components to squeeze out a 3.7% generation increase despite a 0.2% DNI drop.

That kind of performance earned it NDRC recognition as a national strategic emerging industry benchmark worldwide. The plant's 27,135 heliostat sets, each covering 20 m², form the mirror field backbone driving this sustained output.

Underpinning the plant's reliability is a 7-hour molten salt storage capacity supplied by 10,093 tons of molten salt, enabling continuous power generation well beyond daylight hours.

How Linear Fresnel Technology Made Its Chinese Debut

While tower and parabolic trough systems dominated China's early CSP rollout, Linear Fresnel technology took a different path to its Chinese debut — slower to arrive, but no less significant.

You'll find its origins in lectures and research that surfaced internationally around 2017, introducing the concept of precise mirror alignment across flat, ground-level arrays directing sunlight onto fixed receiver tubes.

China didn't rush deployment. Construction on the landmark Hami project didn't begin until 2023, with its 100 MW Linear Fresnel CSP section synchronizing to the grid on September 18, 2025 — 42 days ahead of schedule.

That milestone confirmed the technology's commercial maturity on Chinese soil and established it as a credible, large-scale alternative within the country's rapidly expanding clean energy portfolio. The plant's eight-hour molten-salt storage capability converts the CSP block into a fully dispatchable peaking asset, enabling reliable generation well beyond daylight hours.

The broader Hami installation pairs the CSP block with a 900,000 kW PV array, forming an integrated multi-source clean energy hub projected to generate 1.86 billion kWh of clean electricity annually. This kind of large-scale, integrated infrastructure mirrors the philosophy behind open scientific platforms like the AlphaFold Protein Structure Database, where pooling resources across systems dramatically accelerates progress that no single specialized approach could achieve alone.

Can China Realistically Hit 3 GW Solar Thermal by 2020?

The Linear Fresnel milestone at Hami marked a meaningful step forward, but it arrived decades after China had already set — and missed — some of its most ambitious solar thermal targets. China's draft Five-Year Plan targeted 5 GW of CSP capacity by 2020, yet actual deployment reached only 538 MW. You can see how policy uncertainty slowed momentum — the National Energy Bureau kept revising targets without resolving grid integration challenges that consistently bottlenecked large-scale solar thermal projects.

While PV raced past its 105 GW target by 140%, solar thermal couldn't match that trajectory. The 3 GW threshold wasn't realistic given those structural barriers. Still, the technical knowledge China built through limited CSP deployment positioned it for more credible scaling attempts beyond 2020. Much like how DARPA linked universities and defense contractors to accelerate network development through coordinated government funding, China's state-directed research programs attempted to bridge the gap between academic solar thermal knowledge and large-scale commercial deployment. China's total installed operational PV capacity reached 165 GW by end of September, underscoring just how dramatically the country's solar ambitions had shifted toward photovoltaics over thermal alternatives. By the close of 2020, cumulative installed solar capacity had surged to 252.5 GW, reflecting the extraordinary pace at which China continued to expand its photovoltaic infrastructure in the years that followed.

How Solar Thermal Strengthens China's Broader 2020 Renewable Strategy?

Solar thermal didn't operate in isolation — it anchored China's broader push to diversify its 2020 renewable energy mix alongside wind, hydro, and biomass.

You can see how its integration into hybrid renewable bases directly strengthened grid resilience by offering dispatchable, storage-capable generation that intermittent sources couldn't consistently deliver.

China's industrial policy backed this through feed-in tariffs, policy bank capital, and phased commercialization targets — pushing solar thermal from small-scale heating by 2010 toward large-scale electricity generation by 2020.

That structure supported the 90–100 GW installed capacity goal and the 18% primary energy target.

Solar thermal also extended electricity access to western regions, pairing energy security with sustainable development and positioning renewables as the foundation for China's projected 50% energy share by 2050. By March 2025, the results of this long-term diversification strategy became measurable, with combined wind and solar capacity officially surpassing coal at 1,482 GW.

In 2021, 43% of global renewable power capacity additions occurred in China, reflecting the cumulative impact of sustained policy support and diversified technology deployment across the preceding decade.

This broader momentum in scaling energy infrastructure mirrors developments in other sectors, where reusable rocket technology has similarly demonstrated how sustained investment and iterative engineering can drive launch costs down by approximately 75%, from $10,000 per kilogram to around $2,500 per kilogram to orbit.
