Project Development
Select the operator, secure permits, close the financial structure, and build. Grid connection is the most critical and unpredictable process: in Colombian practice it takes between 3 and 12 months.
Solar operator selection
The operator designs, builds, and maintains the system for 15-25 years. The contract is executed within the trust fund through a competitive process with weighted criteria.
| Criterion | Weight | What to evaluate |
|---|---|---|
| Proven experience | 25% | Similar projects executed in Colombia, especially in communities |
| Competitive price | 20% | COP/Wp installed, including O&M; compare against market reference costs |
| O&M capability | 20% | Local presence, response times, preventive maintenance plan, performance guarantee |
| Community commitment | 15% | Experience working with communities, willingness to train, local employment |
| Financial soundness | 10% | Financial statements, credit history, execution capacity |
| Warranties | 10% | Panels (25 years min.), inverters (10-15 years), labor (2-5 years), performance (90% year 1, 80% year 25) |
The Playbook publishes two different weightings -- verify which one you are using
Ch. 15.3 weights as follows: Experience 25% -- Price 20% -- O&M Capability 20% -- Community Commitment 15% -- Financial Soundness 10% -- Warranties 10%.
But the ToR template in Ch. 28 weights differently: Experience 25% -- Technical Proposal 20% -- Price 25% -- O&M Plan and Warranties 15% -- Commitment to Local Employment and Community Training 15%.
Both sum to 100% and both come from the same document, but they are not the same matrix: the ToR version gives more weight to price and merges O&M with warranties. Choose one before publishing the ToR and use it consistently, because changing weights after receiving proposals is grounds for challenge.

Why this table does not include a calculated score
The Playbook publishes the criteria and their weights, and publishes a list of reference operators, but does not score any operator against any criterion. Assigning scores here would mean fabricating them, and a fabricated ranking on a public website is exactly the kind of data a bidder can challenge. The scoring is produced by the evaluation committee with actual proposals in hand, following the Ch. 15.4 process: ToR → invitation to minimum 3 operators → 15-20 business days for proposals → weighted evaluation → visit to reference projects → negotiation → award by the fiduciary committee → EPC contract and O&M contract signature.
The ready-to-use ToR template is in Tools.
Permit pathway
Eight processes with six different agencies. The bars show each one's estimated timeline on a 180-day scale.
| Permit | Agency | Estimated duration (0-180 days) | Max. (days) | Estimated cost |
|---|---|---|---|---|
| Land use | Municipal Planning | 5-10 days | 10 | COP $100K-300K |
| Net metering enrollment | Grid operator | 15-30 days | 30 | No cost |
| RETIE certification | ONAC-accredited inspection body | 15-30 days | 30 | COP $2-5M |
| Construction permit | Building authority / Municipal Planning | 15-30 days | 30 | COP $500K-2M |
| Environmental clearance | CAR / regional environmental authority | 30-60 days | 60 | Variable |
| AGRC/GDC registration | CREG | 30-60 days | 60 | No cost |
| Grid connection request | Grid operator | 30-90 days per the Playbook -- 3 to 12 months in practice | 90 | COP $5-50M depending on capacity |
| Prior consultation (if applicable) | MinInterior (Ministry of the Interior) | 60-180 days -- mandatory if the project affects territories of indigenous, Afro-Colombian, or Raizal communities | 180 | Variable |
These bars are durations, not a schedule
The Playbook publishes how long each process takes, but does not publish start dates or dependencies between them. Drawing a Gantt chart with precedences here would mean inventing them. What the Playbook does say: the grid connection request to the grid operator is the most critical and potentially slowest process (Ch. 17.2), and although the table estimates 30-90 days, in Colombian practice the process takes between 3 and 12 months depending on the operator and available capacity. File it first and plan around it, not the other way around.
The Comunidad Solar La Estrecha project, in Medellin, was the first to complete a legalized grid connection with EPM and register the commercial boundaries with XM.
What the municipality can accelerate (Ch. 17.3)
- Construction permit -- priority processing for energy community projects -- 15-20 days
- Land use -- verify compatibility in POT/EOT and issue certificate -- 5-10 days
- Public rooftop assignment -- administrative act authorizing use -- 10-15 days
- Road occupancy permit -- if needed for connection works -- 5-10 days
Environmental assessment: good news (Ch. 16.4)
Projects under 10 MW do not require an environmental license (Decreto 2041 of 2014). They only require registration with the Regional Autonomous Corporation. No energy community project comes close to that threshold: the CREG 101 072 regulatory ceiling is 5 MW.
Exceptions: projects in protected areas require clearance from the competent environmental authority; those affecting vegetation require a forestry use permit; and prior consultation is mandatory when the project affects the territories of ethnic communities.
The municipality takes on no debt
The structure is project finance through a trust fund: assets are legally protected, the community participates via Community Participation Certificates, and the municipality does not borrow.
Capital structure
The municipality takes on no debt: the structure is project finance through a trust fund. Move the slider to see how the rest of the stack changes.
Construction schedule
Between 8 and 14 weeks from mobilization to commissioning, depending on size and complexity.
-
Mobilization -- 1-2 weeks
Equipment transport, camp setup, and security. Quality control: equipment inspection on arrival -- must be Tier 1, undamaged, and with complete spec sheets. Verified jointly by the operator and the community.
-
Mounting structure -- 2-3 weeks
Installation of bases, rails, and supports. Quality control: before mounting panels, a civil engineer verifies the anchoring conforms to design and can withstand 120 km/h winds.
-
Panel installation -- 2-4 weeks
Mounting panels on the structures. Playbook specification: monocrystalline 540-580 Wp, efficiency above 21%, BloombergNEF Tier 1, with 25-year performance warranty (90% in year 1, 80% in year 25).
-
Wiring and inverters -- 1-2 weeks
Electrical connection and inverter installation (10-15 year warranty, RETIE certification). Quality control: before connection, an electrical engineer verifies RETIE compliance, grounding, and protections.
-
Grid connection -- 1-2 weeks
Connection point, bidirectional meter, and testing. Quality control: RETIE inspection by the ONAC body before energizing -- without an issued RETIE certificate, the system is not energized.
-
Commissioning and handover -- 1 week
Six formal tests: insulation, grounding (resistance <10 ohms), performance (actual vs. expected generation over 72 continuous hours), grid injection, safety (protections and anti-islanding disconnection), and remote monitoring. Acceptance criterion: performance ≥ 95% of nominal capacity.
What the community must require at formal handover (Ch. 19.4)
Handover minutes signed by the operator, the community, and CleantechHUB -- RETIE certificate -- as-built drawings -- operation and maintenance manuals -- warranty certificates for all equipment -- access to the remote monitoring system -- operator emergency contact list -- basic training for 3-5 community members in system operation and safety.
If any of these are missing, the handover is not complete. The minutes are what activates the warranties.
System commissioned and handed over
Phase 4 determines whether the program is replicated: monitor, maintain, and publish the results.
