Former Colombian President Andres Pastrana Visits Weltrus to Review Energy Storage and Colombia’s Energy Transition
Key Takeaway
A presidential-level energy exchange is a structured visit in which a former head of state and a manufacturer’s technical team review product lines, certificates, and a host-country energy-transition plan. Weltrus hosted former President of Colombia Andres Pastrana and his delegation to review energy storage products and discuss how PV plus storage can support Colombia’s energy mix, carbon reduction, and C&I and residential adoption. The visit is an exchange of views. It is not a government procurement award.

The Problem Colombia’s Mix Still Has
Colombia is often described as a clean-power country because hydropower still accounts for most installed electricity capacity—about two-thirds in 2024 on published capacity breakdowns. That statistic is real, and it is incomplete. A hydro-heavy system is exposed to hydrological variability. Dry years cut reservoir output. Evening demand does not wait for the next wet season. Thermal peakers and diesel fill gaps that hydro cannot cover on schedule.
At the same time, Colombia sits near the equator with a solar resource that published studies put at a national-average global horizontal irradiance (GHI) of about 4.5 kWh/m²/day, above the often-cited world average near 3.9 kWh/m²/day. Caribbean departments and La Guajira frequently see values around 5.5 kWh/m²/day. Irradiance is relatively stable across months compared with higher-latitude markets. The missing piece is not sunlight. It is the ability to time-shift that sunlight into hours when the grid, a factory, or a home actually needs power.
EPCs and industrial buyers in Colombia therefore face a practical problem: solar without storage follows the sun; hydro without storage follows rainfall; diesel follows a fuel truck. Integrated PV plus energy storage is the topology that lets a site keep midday generation for evening peaks, ride through outages, and cut carbon without pretending that a hydro-dominated national mix already solved behind-the-meter reliability.
Legal and tariff frameworks already exist for non-conventional renewables—Ley 1715 as the foundation and later energy-transition updates such as Ley 2099—plus CREG rules on distributed generation. Those instruments do not, by themselves, specify cabinet SKUs, fire-suppression layouts, or UN packing. Buyers still need a manufacturer that can document product, export, and service. That is the discussion Weltrus opened with the visiting delegation.
What the Visit Covered
Weltrus hosted former President of Colombia Andres Pastrana and his delegation for an on-site exchange. The agenda was product and planning, not a photo-only event. The former president and the Weltrus team reviewed energy storage hardware, discussed Colombia’s new-energy development path, and exchanged views on how a compliant, localized PV-plus-storage offer can support industrial, commercial, and residential adoption.
The company received a favorable assessment of its energy storage portfolio and a constructive discussion on planning: where storage sits relative to hydro variability, how C&I sites can cut diesel runtime, and what a localized rollout requires from certificates through commissioning. Weltrus did not treat the visit as a substitute for interconnection studies or a signed offtake. It treated the visit as a channel-opening exchange—exactly the purpose stated in the internal visit summary: broaden international perspective, open overseas market conversations, and set a Latin America work plan that is executed with partners on the ground.
Weltrus’s public position for Colombia, as briefed for this visit, is direct: leverage abundant solar irradiance; deliver integrated PV plus storage; implement in a compliant and localized way; supply PV modules, energy storage systems, and full-spectrum technical services; help optimize the energy mix, cut carbon emissions, and accelerate clean-energy adoption for commercial, industrial, and residential users. That sentence is a work plan. The rest of this article turns it into buyer-checkable pieces.
Colombia’s Solar Resource in Numbers
Do not sell “abundant sun” without units. The table below is the planning range Weltrus uses when talking with Colombian EPCs. Site yield still needs a PVsyst or equivalent run on the actual coordinates, albedo, and soiling. National averages are a screening tool, not a COD guarantee.
| Planning input | Published range / status | What it means for PV + storage |
|---|---|---|
| National-average GHI | About 4.5 kWh/m²/day (literature using IDEAM-validated NREL-class data) | Year-round PV is viable; storage is for timing, not for inventing sun |
| High-resource regions | Caribbean / La Guajira often near 5.5 kWh/m²/day | Utility and C&I hybrid plants have stronger midday surplus to shift |
| Seasonality | More stable than mid-latitude Europe; still not a flat 24-hour profile | 2–4 hour BESS is a common first design band for evening peaks |
| Installed mix (2024 capacity shares, published breakdowns) | Hydro on the order of ~66%; solar still a single-digit share of capacity | Solar growth without storage can collide with hydro surplus and evening ramps |
| Policy stack | Ley 1715, later transition law updates, CREG distributed-generation rules | Incentives exist; interconnection and equipment documents still gate COD |
The operational implication is simple: Colombia does not need a lecture on whether solar works. It needs storage duration, interconnection headroom, and a service model that matches C&I roofs, industrial yards, and homes. For how storage operating modes differ—peak shaving, backup, load shift—see peak shaving vs backup vs load shift for BESS. For sites that still run diesel peakers, the conversion logic is in diesel peakers to solar plus storage.

PV Plus Storage: What Actually Changes
Integrated photovoltaic plus energy storage is a system in which PV modules, inverters or hybrid conversion, a battery energy storage system (BESS), and a control layer are designed as one interconnection package. The PV harvests. The BESS time-shifts or backs up. The controller respects export limits, transformer kVA, and the site’s load. Without that package, a Colombian buyer often gets a PV quote and a battery quote that do not share a one-line diagram.
What changes on a real site:
- Evening peak: Midday PV that would otherwise export or curtail can discharge after sunset when C&I demand and household cooking loads rise.
- Drought hedge: Storage does not replace national hydro. It reduces a factory’s exposure to tariff spikes and diesel when the hydro system is tight.
- Power quality and backup: C&I ESS can support ride-through for defined loads if the PCS, transfer scheme, and transformer are sized together—not from a brochure kWh number alone.
- Carbon accounting: Displacing diesel kWh is measurable. Claiming “green” from PV that is clipped or exported without a storage dispatch plan is not.
Weltrus’s role in that stack is manufacturer plus technical service: PV modules, Home ESS, C&I ESS, utility-scale ESS, and EPC support where the project scope includes design and delivery. Overseas project experience cited for this exchange includes Australia, New Zealand, France, Vietnam, and Romania, with additional Latin America utility-scale discussions in progress. Those markets are not Colombia. They are evidence that export documentation, FAT, and commissioning are already part of the operating system—see the BESS FAT protocol before shipment and a factory walkthrough checklist if you will visit production before PO.
Weltrus Product Stack for Colombia
Map the visit conversation onto SKUs, not adjectives. The right class depends on load, duration, and who signs the interconnection.
| Class | Typical Colombia use | What to bring to an RFQ | Not a fit when |
|---|---|---|---|
| Home ESS | Residential backup, self-consumption, outage ride-through | Load list, roof PV size, backup circuits | The home needs a generator-replacement study you have not scoped |
| C&I ESS | Factories, warehouses, commercial roofs, peak shaving | 15-minute demand, transformer kVA, tariff | Service capacity cannot accept charge rate without a utility upgrade |
| Utility-scale ESS | Hybrid plants, energy shifting, grid services where contracted | Duration (hours), PCS MW, interconnection study | The offtake and grid code are undefined |
| PV modules | Paired arrays for the same sites | Wp class, bifacial/monofacial, IEC 61215/61730 pack | Modules are specified with no inverter or structure package |
| EPC support | Design, delivery, commissioning with local installers | Scope split, FAT, SAT, spare parts | The buyer wants a price with no one-line diagram |
Capacity classes and cabinet vs container form factor are covered in the Weltrus C&I energy storage product line overview and the complete guide to C&I energy storage in 2026. Do not pick MWh from a visit photo. Pick MWh from interval data and a transformer check—transformer capacity limits for behind-the-meter C&I BESS.
Certificates and Localized Delivery
Localized delivery means the file pack and the installation method match Colombian import, transport, and grid-connection practice. It does not mean a translated brochure. For this visit, Weltrus listed the following certificate families as the current export baseline. Request copies mapped to the shipped SKU and revision.
| Document | What a Colombia-bound buyer uses it for |
|---|---|
| IEC 62477-1 | Power electronic converter safety for PCS / conversion equipment |
| IEC 62933-5-2 | Electrical energy storage system safety (system-level, not a cell-only report) |
| IEC 61000-6-2 / 6-4 | EMC immunity and emissions for industrial environments |
| UL 9540A | Thermal runaway fire-test data often requested by AHJs and insurers |
| UN 38.3 | Lithium battery transport tests; must match the packed configuration |
| UN 3536 | When the product is classified as a lithium battery installed in cargo transport unit |
Export compliance is a separate article: UN38.3 and CE export compliance for BESS. HS codes and duty planning for cabinets: HS codes and import duty for BESS cabinets. Localized implementation also means local EPCs and installers own permits, CREG interconnection paperwork, and Spanish-language O&M. Weltrus supplies product, documentation, and technical support; it does not replace a Colombian electrical contractor’s license.
Who Weltrus Wants to Work With
The visit summary is explicit about the partnership request. Weltrus is looking for Colombian EPCs, agents, distributors, installers, and government agencies that can take a documented product into a permitted site. Introductions from visiting leaders are welcome as bridges. They are not a substitute for a commercial RFQ.
A useful first package from a Colombian partner looks like this:
- Site type: home, C&I roof or yard, or utility hybrid
- Target kW and usable kWh, plus hours of backup if backup is the driver
- Existing PV kW AC, if any, and export limit
- Transformer or service size, even if only nameplate kVA
- The certificate list your customs broker and AHJ already named
- Who commissions: Weltrus remote support, local installer, or joint SAT
If you cannot fill those six lines, start with a load list and a one-line sketch. Do not start with a round MWh number copied from another country’s tender.

Frequently Asked Questions
Did former President Andres Pastrana visit Weltrus?
Yes. Weltrus hosted former President of Colombia Andres Pastrana and his delegation for a structured exchange on energy storage products and Colombia’s new-energy development. The visit was a technical and policy discussion, not a government procurement award.
Why does Colombia need solar plus storage if the grid is already hydro-heavy?
Hydropower still supplies most of Colombia’s installed capacity, so dry years and evening peaks expose the mix. National-average GHI is about 4.5 kWh/m²/day, with higher values in the Caribbean and La Guajira. Storage shifts midday PV into later hours, supports C&I continuity, and reduces diesel peaker use.
Which Weltrus products are relevant for Colombia?
Home ESS for residential backup and self-consumption, C&I ESS for factories and commercial roofs, utility-scale ESS for hybrid plants, PV modules, and EPC support. The right class depends on load profile, interconnection limits, and whether the site needs backup, peak shaving, or energy shifting.
What certificates should a Colombia-bound BESS RFQ request?
Ask for copies mapped to the shipped SKU: IEC 62477-1, IEC 62933-5-2, IEC 61000-6-2/4, UL 9540A, UN 38.3, and UN 3536 where the pack format requires it. Certificates without serial or revision mapping are not export clearance.
How can a Colombian EPC or distributor start a partnership with Weltrus?
Send site type (home, C&I, or utility), target kW/kWh, grid-connection notes, and the documents your customs broker requires. Weltrus will map a product class and a localization checklist. Introductions to agents, installers, and agencies are welcome; they do not replace a written RFQ.
