The cleanest read on Mexican renewable energy in 2026 is that private capital wants in — five times more than the state utility has room for — but the rules under which that capital flows have been rewritten at the constitutional level, and the manufacturing footprint sitting downstream of those rules is uneven on purpose. Wind blades are made in Matamoros and Juárez and shipped to American wind farms running on the ERCOT side of the border. Wind towers are built in Altamira and Coahuila, including the first offshore wind tower ever produced in the Americas. Solar panel assembly is showing up in Yucatán, Durango, Puebla, and Jalisco — most of it Chinese-anchored, most of it final-stage. Geothermal is operated almost entirely by CFE itself. Battery cells are not made in Mexico at any scale — and no announced project closes that gap before 2027. The page that tells you about the 38 GW of bids without telling you about the 0 GWh of cells is the page that gets the 2026 picture wrong.
The 38 GW signal
On February 6, 2026, Mexico’s Federal Electricity Commission (CFE) opened tender CFE-001-2026 — the first scheme launched under Sheinbaum’s 2025–2030 National Electricity System Strengthening and Expansion Plan — seeking private partners to build 7.5 GW of new renewable capacity through “mixed schemes”: 3.55 GW of utility-scale solar, 2.85 GW of wind, 1 GW of battery storage, and 100 MW of regional concentrated solar (Energy & Commerce, BNamericas, February 2026). By the original prequalification deadline, more than 200 wind and solar projects had been submitted, totaling nearly 38 GW of proposed capacity. CFE shortlisted approximately 13 GW for the next stage on April 13, 2026 (BNamericas). The investment guarantee from selected partners was cut from 15% of capital expenditure to 3%, in a deliberate effort to widen the field, and contract signing was pushed from May 29 to June 8, 2026, with deposit guarantees due June 5 (BNamericas, April 20, 2026; Strategic Energy Europe, April 22, 2026). Expected PPA prices land in the 35–70 USD/MWh range. CFE will hold a 54% equity stake in every selected project — a structural floor written into the Mexican Constitution on March 19, 2025.
That constitutional reform is the policy anchor under all of this. On October 17, 2024, the Mexican Senate voted to give CFE constitutional preference; the implementing energy reform — eight new laws covering the electricity sector, hydrocarbons, geothermal, and biofuels — came into force on March 19, 2025 (Haynes Boone via Lexology; Norton Rose Fulbright). It reverses 2024 Supreme Court rulings that had struck down portions of the 2021 Ley de la Industria Eléctrica for violating economic-dispatch logic. CFE and PEMEX reverted from “productive state enterprises” to “public companies of the State.” The independent Energy Regulatory Commission (CRE) and National Hydrocarbons Commission (CNH) were folded into a centralized National Energy Commission reporting directly to the executive. The CFE 54% floor is the operative consequence: every utility-scale solar or wind project that qualifies under the 2026 mixed-scheme tender flows through a CFE-majority structure, and 70% of generation output is sold back to CFE under 25-year power-purchase agreements.
The 38 GW signal sits inside that frame. Read against five years of headlines about regulatory chilling, AMLO-era project cancellations, and the Iberdrola nationalization war, the response volume is the surprise: nearly five times the available capacity, despite the new equity floor, despite the dispatch-priority disputes that paralyzed the LIE through 2024. Private capital is willing to take a 46% equity position with a guaranteed 25-year offtaker, and the queue is long enough that CFE just narrowed the financial-guarantee bar to keep more bidders in.
The Cox transaction one week before contract signing puts a number on it. On April 28, 2026, Spanish utility Cox announced the acquisition of Iberdrola Mexico for approximately $4 billion — a 12 GW Mexican renewable-and-thermal pipeline, including the assets that survived Iberdrola’s earlier 2023 partial sale to the Mexican government’s Mexican Infrastructure Partners trust (PV-Tech, April 28, 2026). Cox is buying back into a Mexican renewable market on the same week CFE is signing partnership contracts that will obligate state-equity stakes in every winning project. The Spanish utilities AMLO publicly fought are not exiting Mexico; they are restructuring around the new rules.
Plan Sonora is the federal side of the same thesis. The Puerto Peñasco solar park — anchored by CFE in Sonora and positioned as the keystone of a $48 billion state strategy that fuses solar, lithium, and chip ATP-Ready packaging — has now activated 420 MW across two phases (Phase I, 120 MW operational April 30, 2023; Phase II, 300 MW operational September 14, 2024, supplying Mexicali, per Proyectos México). Phase III began construction in February 2026; the federal government launched a $363 million tender for Phase IV (280 MW plus 84 MW of battery storage) on January 6, 2026 (BNamericas; Rocky Point Times). At completion, the complex reaches roughly 1 GW with integrated BESS. SENER’s 2025–2030 plan adds 21,846 MW of total system capacity (CFE 13,024 MW direct, 2,422 MW Pemex cogeneration, balance private), backed by an $8.17 billion / 145-project transmission program targeting 6,735 km of new strategic lines and 524 substations by 2030 (Expansión, February 2025; SENER).
Mexico builds the wind blades. The wind farms run on the other side of the border.
A page about Mexican renewable manufacturing that does not lead with the TPI Composites story misses 2025’s largest sector restructuring. TPI Composites — the Scottsdale-headquartered independent wind-blade manufacturer that produced over 100,000 blades since 2001 and operated some of the largest blade plants in Matamoros, Tamaulipas and Ciudad Juárez, Chihuahua under long-running supply agreements with GE Vernova and Vestas — filed for Chapter 11 bankruptcy on August 11, 2025 in the United States Bankruptcy Court for the Southern District of Texas, alongside 21 affiliated debtors, against $1.077 billion in liabilities and $591.7 million in assets (TPI Composites press release, August 11, 2025; Globe Newswire). The Mexico business itself was healthy: in TPI’s Q4 2024 earnings, management stated that “demand for our blades out of our Mexico factories exceeds current capacity for 2025” and the company had moved Juárez production lines to 24/7 operation. The bankruptcy was driven by liquidated damages on complex new blade designs and US-side margin pressure, not Mexican operational failure.
Vestas — TPI’s largest customer, accounting for approximately 35% of TPI’s 2024 net sales — was named the stalking-horse bidder. The planned auction was cancelled on December 12, 2025 when no other approved bids materialized; Vestas became the sole acquirer of TPI’s Mexican subsidiaries (Bloomberg Law via MarketScreener, December 16, 2025). Per TPI’s March 2026 8-K filing, the structure of the Mexico transaction is an Equity Commitment Agreement issuing new equity in TPI Mexico V and VI for $13,999,999 in cash plus assumed liabilities, alongside a separate Mexico asset sale for $1.00 plus assumed liabilities; outside date June 30, 2026, conditional on Bankruptcy Court orders, lender consents, and Oaktree lien releases. India’s Chennai plant goes to Vestas for $10 million. The same 8-K disclosed an Event of Default under TPI’s debtor-in-possession credit agreement; an amended final DIP order was approved on April 10, 2026. The transaction is not closed; the Vestas takeover of Mexican operations is the path being executed.
For the page reader, the operational read is direct: Mexico’s wind-blade manufacturing capacity is consolidating from a third-party EMS model under TPI to in-house manufacturing under Vestas, while continuing to supply GE Vernova through transitional agreements. Demand for Mexican blade output has not dropped; the corporate ownership is what’s changed. The Matamoros plant — closed in June 2024 during TPI’s restructuring — is the asset Vestas paid the headline figure to acquire. Juárez has remained operational throughout.
Beyond TPI, the wind component cluster is more diversified than the headline restructuring suggests. Siemens Gamesa is supplying 60 SG 4.5-145 onshore turbines (249 MW) for Enel Green Power’s Amistad III and IV wind farms in Coahuila, with blades and towers manufactured locally in Mexico. Speco Wind Power operates in Monclova, Coahuila; CS Wind and Trinity Industries de Mexico maintain steel-tower fabrication footprints across Tamaulipas and the northern corridor. The most strategically interesting single facility may be Windar Renovables in Altamira, Tamaulipas: in December 2024, the plant delivered the first offshore wind tower ever manufactured in the entire American continent, a continental-first credential that anchors Mexico’s position on the offshore-wind manufacturing map even as the offshore wind market in Mexico itself remains nascent (Windar Renovables press release, December 12, 2024; El Sol de Tampico, August 22, 2025).
The destination geography is the load-bearing detail. The wind farms in Tamaulipas and northern Coahuila possess asynchronous grid ties feeding directly into the Texas ERCOT system rather than the Mexican national grid, and most of the wind blades and towers manufactured in northern Mexico ship to US installation sites under USMCA Chapter 84/85 terrestrial transit. The Inflation Reduction Act’s Section 45X advanced manufacturing credit creates a counterweight: 45X rewards US-soil production of wind blades, nacelles, and towers with per-unit credits sized to incentivize reshoring. The Foreign Entity of Concern (FEOC) rules — clarified through IRS Notice 2026-15 on February 12, 2026 — additionally disqualify products that exceed thresholds of “material assistance” from China, Russia, or Iran (PV Magazine USA, July 2025; Solar Power World, February 2026; Project Finance, March 2026). For Mexican manufacturers, the math is delicate: USMCA-origin assembly in Mexico can avoid Section 232 metals tariffs and qualify for tariff-free US entry, but cannot capture US-side 45X credits, and must demonstrate non-Chinese material sourcing to avoid disqualifying downstream US developers from technology-neutral 45Y/48E credits. The cross-link to trade compliance is binding here, not optional.
Solar is rising. Battery cells aren’t being made.
The solar story splits in two: Mexican-soil panel and cell assembly is showing up — slowly, mostly Chinese-anchored, mostly final-stage — while utility-scale solar generation additions slowed sharply in 2024 as transmission constraints bit. ASOLMEX’s data via SolarPower Europe shows utility-scale capacity additions falling from 925 MW in 2023 to 523 MW in 2024 — the lowest annual addition since 2017. Distributed solar — rooftop and small commercial, exempt from CFE’s interconnection queue — is now driving most of the country’s solar growth. GlobalData forecasts Mexican solar PV reaching 37.8 GW by 2035 from approximately 12 GW today (GlobalData, December 2025).
On the manufacturing side, four announcements from 2024–2026 are concrete enough to track. Ultimate Solar Advanced Technology (USAT) is deploying MX$2.43 billion in Kanasín, Yucatán; phase one at MX$1.52 billion targets up to 1 GW per year of next-generation solar cell production. Solarever Group broke ground on a 13.6-hectare cell-and-panel plant in Durango’s Parque Industrial CLID at $197.9 million; the plant is scaled for 1.2 GW of PERC and TopCon cell capacity for Canadian and US export. Shijing Solar is investing in Puebla to manufacture N-type TOPCon cells, scheduled for full production in 2025. Tonalli inaugurated a solar panel factory with 200,000-unit annual capacity in June 2025 (PV Magazine, June 27, 2025). Canadian Solar (CSI Mexico) and Enphase Energy maintain operational presences in Tijuana / Juárez and Monterrey respectively. The distinction worth keeping is the one between manufacturing and generation: Risen Energy’s 117 MW Durango solar park installs imported modules without setting up a fabricator; Tongwei partnered with Grupo Dragón on module supply for generation projects, not on a Mexican factory; JA Solar formalized a 400 MW distribution agreement with Exel Solar in April 2026 for imported panels rather than domestic assembly. Trina Solar’s earlier reports of a $1 billion Nuevo León factory have not produced verifiable on-the-ground activity, and Trina exited direct US module manufacturing in December 2025 by selling its 5 GW US module plant to T1 Energy (PV Magazine USA, December 26, 2025).
The battery story is the load-bearing constraint. As of late April 2026, Mexico has zero operational gigafactory-scale battery cell manufacturing plants, and no announced project closes that gap inside the 2027 horizon. The Tesla Gigafactory in Santa Catarina, Nuevo León — announced in March 2023 at $5 billion on a 1,194-hectare “Ecological Project Mario” site — is definitively cancelled. Elon Musk halted execution in July 2024 citing US tariff uncertainty; by March 2026 specialized hiring pipelines had vanished, local roadwork was abandoned, and the site was confirmed in ruins by Milenio’s investigation (Milenio, March 2, 2026). BMW San Luis Potosí is scaling toward 2027, but the BMW Group press release titled “Construction of high-voltage battery assembly gets underway at BMW Group Plant San Luis Potosí” makes the scope explicit: pack assembly under the Neue Klasse architecture, drawing on imported cells, not domestic cell production. Stellantis launched the 2026 Jeep Cherokee Hybrid at its Toluca complex in 2026 sourcing battery cells from the Samsung SDI / Stellantis Kokomo, Indiana joint venture (initial 23 GWh US capacity). Ford abandoned LG Polish cell sourcing for the Hermosillo Mustang Mach-E line and substituted LG’s Michigan plant. General Motors scaled Ramos Arizpe EV production back to a single shift in 2025, cutting roughly 1,900 workers as US EV demand softened. The federal Olinia EV battery manufacturing project announced by SENER on November 12, 2025 is small-scale and untested — built around Mexico’s homegrown Olinia EV program rather than around major OEM cell supply.
The upstream lithium story is the structural reason none of this has resolved. Following AMLO’s 2022 lithium nationalization decree and the subsequent 2023 cancellation of nine concessions covering approximately 10,000 hectares — including those held by Ganfeng Lithium’s Mexilit subsidiary — the state lithium company LitioMx has produced no commercial output. Ganfeng’s ICSID arbitration against Mexico (case ARB/24/21) was suspended in December 2025 (BNamericas, August 28, 2025; The Sonora Post, February 13, 2026; Quinto Elemento Lab, October 2025). The Sonora lithium reserve sits beneath the Sonora desert, geographically inside the same state where Plan Sonora is concentrating $48 billion of solar-and-chip investment, and economically frozen until either the arbitration resolves in Ganfeng’s favor or LitioMx develops operational capacity it has not yet demonstrated. The cathode-precursor and Tier-1 supply layer that would feed any future Mexican gigafactory is, in practice, on hold.
The cross-link to Northwest Mexico — Cerro Prieto in Baja California, Plan Sonora’s Puerto Peñasco solar complex, the Windar Renovables Altamira offshore-tower plant, and the TPI / Vestas Matamoros + Juárez wind-blade footprint in Tamaulipas and Chihuahua — is load-bearing here. The renewable-manufacturing geography of Mexico sits inside the Northwest’s three-state border corridor, and the tariff, transmission, and water constraints that shape it are the same ones the electronics and semiconductor sector navigates around the Plan Sonora chip ATP-Ready bridge. The two sectors are joined at the Sonora hip — and the page reader who has the renewable thesis without the trade-compliance and electronics-sector context has only half the operating picture.
