Operator Comparison

The 7 solar energy operators with documented profiles in Colombia, compared on the figures their sources actually publish — and only on those.

How to read this comparison

The gaps are real. When a cell says "Not documented" or "Not disclosed" it is because the operator's source does not publish that data — not because it has not been loaded. EPM does not publish capacity, number of projects or prices; Enel, AES and Celsia do not document the founding year of their Colombian entity. None of those cells is filled with an estimate.

Total MW and solar MW are separate columns on purpose. Enel reports 4,011 MW, but most is hydroelectric: only 688 MW are solar. Comparing Enel's 4,011 MW against Unergy's 50 MW says nothing about community energy. The charts on this page use solar MW for that reason.

Parent-group founding years are not those of the Colombian entity. Grupo Enel (Italy) dates from 1962 and AES Corporation (USA) from 1981, but no source documents when their Colombian subsidiary was incorporated. Placing "1962" next to Unergy's "2018" would compare different things, so those cells are left empty and the note explains why.

Comparison

Comparative table

Filter by territorial presence or by price transparency. Sort by any numeric column.

The 7 operators with documented profiles. "Not documented" = the source does not publish the data. "Not disclosed" = the operator explicitly states it does not disclose it. Sort by column; cells with no data always appear last, in both directions.
Operator Founded Solar MW Total MW Projects Departments Prices Detail
Unergy 2018 50 50 72 2 Disclosed
Celsia Solar Not documented 355 1,900 20 8 Disclosed

"Departments" counts the coverage entries from each profile. In Unergy and SunColombia one of those entries is "National", which is not a department: their counts of 2 are not comparable line-for-line with Celsia's or Enel's 8. The source count is shown without normalizing it, because normalizing it would require deciding what "National" means and no source says.

Seven profiles, comparable only if read carefully

From a community solar fintech with 50 MW (Unergy) to the country's second-largest generator with 4,011 MW (Enel), of which only 688 are solar. The charts on this page use solar MW, never total MW, and every empty cell is a real gap in the source, not data pending upload.

Visualization

Capacity and trajectory

Only on published figures. Each chart states who is excluded and why.

Installed solar capacity (MW)

Solar MW, not total MW. Enel appears with 688 MW and not its 4,011 MW, because 3,097 MW of that figure are hydroelectric and say nothing about community solar generation. EPM is not shown: its profile does not document installed capacity.

Unergy trajectory: cumulative mini-farms

Unergy is the only operator with a time series in the corpus: 4 mini-farms in 2023, 31 in 2024, 72 in 2025. None of the other six publishes an annual progression, and that is why this chart has no other lines. Drawing a growth curve for Celsia, Erco or Enel would require fabricating the intermediate data points.

Unergy vs. Erco Energia (documented axes)

Why the radar only compares two operators

A radar needs three or more axes with data for all participants. Of the 7 operators, only Unergy and Erco have the founding year of the Colombian entity, solar capacity and number of projects all documented simultaneously. Celsia, Enel and AES do not document founding year; Enel, AES and SunColombia do not document projects; EPM does not document any of the three. Adding them would require filling the gaps.

Values are normalized to % of the pair's maximum, not absolute units: the actual figures are in the table above. Erco scores 100 on all three axes because it genuinely surpasses Unergy on all three. That Unergy appears at 3 on the projects axis is exact (72 vs. 2,179) — the scale is not smoothed to look better.

There are no axes for "price", "technology" or "community focus". No source publishes a comparable score for those dimensions, and converting profile prose into a number from 1 to 10 would be fabricating it.

Unergy

First mover in regulated energy communities in Colombia.

Model

Community solar fintech platform. Develops solar "mini-farms" of ~1 MW each; users invest from USD 1 through digital uWatts. The "Unergy Vecinos" product allows residential users to join a solar community without their own installation.

Documented figures

  • Founded: 2018
  • Solar capacity: 50 MW (the entirety of its capacity)
  • Projects: 72 — cumulative mini-farms as of 2025. The profile also reports "50+ mini-farms"; the trajectory figure is used as the most recent and dated.
  • Trajectory: 4 (2023) -> 31 (2024) -> 72 (2025)
  • Coverage: National, Antioquia
  • Community focus: yes

Prices Disclosed

No upfront cost for users. Returns for investors: 13% EA, up to 20% with FNCER tax benefits. Figures declared by the operator; Energia Coop does not verify or endorse them.

Celsia Solar

Vertically integrated utility, leader in distributed generation and utility-scale solar.

Model

Generation, transmission, distribution and retail. Three lines: C2Energia (solar farms >8 MW, alliance with Cubico Sustainable Investments), Atera (distributed solutions, alliance with Brookfield) and residential/commercial distributed generation with financing.

Documented figures

  • Founded: not documented. The source describes Celsia as a "historic company" of Grupo Argos without indicating a year. Documented milestone: the country's first utility-scale solar farm (Yumbo, 2017, 9.8 MW).
  • Solar capacity: 355 MW, out of 1,900 MW total
  • Projects: 20 — C2Energia solar farms (>8 MW each) totaling 355 MWp. The source also reports 139 rooftop/ground projects totaling 197.25 MWp under a different business line.
  • Coverage: Valle del Cauca, Antioquia, Tolima, Sucre, Bolivar, Cordoba, Casanare, Cauca
  • Community focus: yes

Prices Disclosed

Distributed generation from 1 kWp. Financing at 1-6 years for 100% of the value. Free maintenance for the first year. PPA model for businesses.

EPM

Colombia's largest multi-utility. First grid operator to activate an energy community under CREG 101 072.

Model

Public utility of Medellin (municipal ownership). Acts as grid operator and retail agent for energy communities. Subsidiaries: Afinia/CaribeMar (Caribbean), CHEC (Caldas), CENS (Norte de Santander), EDEQ (Quindio) and ESSA (Santander).

Incomplete profile

EPM's profile is the sparsest of the seven: it does not publish capacity, projects or prices. Its relevance here is regulatory, not about scale — it is the first grid operator to activate an energy community under CREG 101 072. The empty cells on this page are the source, not data pending upload.
