Utility-scale solar
Solar power at the scale of your operation
An industrial or utility-scale solar park is the core of GIS Power’s approach: solar as primary power, with storage (BESS) that carries it into the hours without sun. We develop it, finance it through a project company, build it and operate it.
What a large-scale solar park is
Generation, storage and interconnection in one projectIt is a photovoltaic plant sized for an industrial load, a development or energy sales, with its own substation, its interconnection and, more and more often, battery storage. Storage changes the role of solar: it stops being daytime power and becomes power delivered when the load calls for it.
Design starts from the load curve and the site’s solar resource. Those two inputs decide how much PV capacity to install, how much energy to store and what backup the plant needs to deliver what the contract promises.
When it is not a fit
- If there is not enough land on site or a nearby property with a viable interconnection.
- If your load is almost entirely at night and the storage it would take is not justified.
- If you need firm power around the clock with no backup: the answer there is a hybrid, not solar alone.
- If your operation at the site may close before the energy contract term.
On site or at a remote location
Two routes with different rules| On-site generation | Remote generation | |
|---|---|---|
| Where it sits | On the load’s property or next to it | On land with a better resource or more area |
| How power arrives | Directly to the load, with or without a grid connection | Through the grid, with interconnection through CENACE |
| What favors it | Available roofs, parking areas or owned land | Large loads or several sites of the same user |
| What must be solved | Space, structure and protection of the existing installation | Land, rights of way, interconnection and the permitting scheme |
The route is set during feasibility, based on the load, the land and the available interconnection.
Scope
From feasibility to operation
One party accountableFeasibility
Load curve, solar resource, land, interconnection and financial model.
Permits
With the CNE and CENACE, plus environmental and local approvals.
Finance
One SPV per project, with a 48 to 180 month energy contract as the source of repayment.
Engineering and construction
EPC with brand-authorized commercial partners, such as Huawei and Pylontech.
Storage
BESS sized to shift energy, shave demand peaks and ride through transients.
Operation
Operation and maintenance with contracted availability.
Permits
What Mexico’s Electricity Sector Law says< 0.7MW
No permit
Exempt generator (LSE art. 19); distributed generation (LSE art. 25).
0.7–20MW
Simplified process possible
Grid-connected self-supply from 0.7 MW (LSE art. 30).
Surplus
Sold only to CFE
An intermittent plant that injects power must have its own backup or pay for it (LSE art. 32).
≥ 54%
Mixed schemes
CFE holds at least 54%, with a term of up to 30 years (LSE art. 40; Regulations art. 73).

Frequently asked questions
Can I sell my surplus power to the grid?
Surplus can only be sold to CFE, and an intermittent plant that injects into the grid must have its own backup or pay for it (LSE art. 32). That is why the park is sized to your load, and storage reduces the surplus.
Do I need storage?
It depends on your load curve. If you consume mostly by day, solar alone can cover a good share. If you consume at night or need firm power, the BESS is what lets the park cover those hours.
Have you built solar parks of your own?
The group’s own experience with solar and BESS generation is in hybrid plants, such as Baker's Bay in the Bahamas, with a 3 MW / 3 MWh BESS. The photos on this page illustrate the technology, not a specific project.
Who owns the park?
Either an SPV that sells you the energy, or your company, through a lease, a loan or cash. The models are compared on the contracting models page.
