The Hermosillo hub, Sonora: from 7 MW to 220 MW on paper

Bajío Ventures · October 2026 · The welfare hubs, one by one

The most important fact about the Hermosillo welfare development hub (Polos de Desarrollo Económico para el Bienestar, PODECOBI) is electrical. SENER’s opinion, published in the DOF, grants it between 1 and 7 MW for 2026–2030. The Proyectos México sheet, revised in August 2026, now mentions reinforcement works for up to 220 MW. The hub covers 546.46 ha in three polygons northeast of the city. It is the third largest of the 15. It has a declaration and a signed state agreement, but it is still in pre-investment and has no announced tenants.

The fact sheet

Declaration (DOF)	26 August 2025, signed 18 August 2025; site approved by the Inter-Ministerial Committee on 30 June 2025
SE–state agreement	22 December 2025
Target sectors	Automotive, semiconductors and specialized electronics, agribusiness, energy, logistics, medical and measurement devices

The land belongs to the state. Sonora’s Ministry of Economy and Tourism is the counterpart. The hub is linked to Plan Sonora.

The incentives are those of the decree of 22 May 2025: a 100% immediate deduction for new fixed assets, plus an additional 25% on the increase in training or innovation spending. In Sonora they run from the agreement of 22 December 2025. Details are in the series overview.

Connectivity

• Hermosillo–Guaymas highway: 650 m.
• Federal Highway 15 and rail line: 2 km.
• Hermosillo airport: 17 km.
• Port of Guaymas: 154 km.
• Nogales border crossing: 265 km.

This is a corridor hub: a port to the south and the US border to the north, on the same highway.

Energy and water

The DOF declaration includes SENER’s opinion. Planned supply is 1 to 7 MW between 2026 and 2030, from the Hermosillo Tres 115 kV substation through a 3.6 km line. A second 40 MVA transformer bank appears only in 2038. SENER identifies a nearby private generation project as a possible supplier. For gas, the file includes a letter from Energas de México dated 21 November 2023 for up to 75 million m³ per year.

The Proyectos México sheet of August 2026 changes the scale. It mentions reinforcement works for up to 220 MW and water at 100 L/s, expandable to 400 L/s. The sheet links to a CFE bulletin that we could not access. The declaration gives 7 MW; Proyectos México now uses 220 MW. Both figures are official. As far as we could read, the second has no public technical document behind it.

The gap matters because of the target sectors. 7 MW fits one or two mid-size auto-parts plants. A semiconductor plant or a data centre alone demands tens of MW. The declared sectors are only viable with the higher figure.

What to watch

• The source of the 220 MW. A CFE or SENER document is missing that states which works, on what date and with what budget.
• Anchor and developer. No developer or tenants had been announced as of 9 October 2026. On 16 April 2026, Marcelo Ebrard said Foxconn executives would visit Hermosillo on 27–29 April. We found no confirmed link to the hub.
• Water. Hermosillo has structural water stress. The 100 L/s in the sheet needs an identified source for each phase.
• Timeline. The December 2025 announcement scheduled the nine hubs without works for Q2 or Q3 2026. Hermosillo is still in pre-investment.

Our reading

Hermosillo has what many hubs lack: land at scale, a logistics corridor and a state with its own energy plan. It lacks what defines an industrial park: a developer and a first company. Until both exist, the hub is a land reserve with a tax incentive.

For an energy developer, the hub is interesting because of the gap between 7 MW and 220 MW. If the grid does not arrive on time, on-site generation will be part of the park’s offer: solar with storage, gas cogeneration under the Energas letter, or a contract with the nearby private plant that SENER already identified. Each plant can also install its own generation below 0.7 MW without a generation permit. We recommend tracking the CFE bulletin and the first developer announcement. Those two signals will decide whether the hub moves from paper to construction.
