The cheapest kilowatt-hour is the one you never use. Before recommending solar, storage, or a new electrical service, we help clients understand where their energy is actually going — and how much of it doesn't need to be spent at all.
Puerto Rico's electricity rates are among the highest in the United States. That reality creates two opposite temptations: over-invest in generation (solar and storage) hoping to offset consumption, or under-invest in efficiency because the retrofit costs seem daunting. Both are usually wrong.
Our approach is disciplined. We audit before we recommend, quantify savings with measured data (not manufacturer literature), and prioritize retrofits by simple-payback period. Then, if generation still makes sense on the reduced load, we scope solar or storage to the actual need — not the pre-audit assumption.
Every study delivers a quantified opportunity list — ranked by payback, engineered with real numbers — plus the construction documents to implement whichever items you decide to pursue.
Screening-level assessment to identify obvious opportunities. Best for facilities exploring whether a deeper audit is worthwhile. Delivers a high-level opportunity summary within days of the site visit.
Our recommended default. Detailed analysis with utility bill review, on-site measurements, and engineered savings estimates for each identified opportunity. Suitable for most retrofit decisions.
Full engineering study with metered data, calibrated energy models, and financial analysis suitable for capital-project approval or performance contracts. Required for larger investment decisions.
12+ months of utility bills, existing drawings where available, equipment inventory, and interval data if the utility can provide it. This is where good studies are made or broken.
Facility walk-through with instrumentation as required — light meters, power loggers, thermal imaging. Interviews with facility staff to understand operational patterns.
Engineered savings calculations for each opportunity, simple-payback ranking, and capital-cost estimates. Report delivered as a decision-support document, not a sales pitch.
For opportunities the client chooses to pursue, we develop PE-stamped construction documents, permit applications, and specifications ready for contractor bidding or in-house implementation.
Every facility is different, but Puerto Rico's climate and electricity rates make certain retrofits reliably cost-effective.
LED retrofits with occupancy sensors and daylight harvesting are among the fastest-payback opportunities in most facilities. Reduced cooling load is a common secondary benefit that shifts the ROI further in favor.
Chiller upgrades, VFD retrofits on pumps and fans, economizer verification, and controls tuning. Tropical climates mean HVAC is often 40–60% of building load — small percentage gains compound quickly.
Power factor correction, motor replacement or right-sizing, and variable-frequency drive additions. Often overlooked but consistently pencils out where operating hours are high.
ASHRAE 90.1 for commercial energy efficiency baselines, ASHRAE 62.1 for ventilation, and Puerto Rico-specific code amendments where they apply.ASHRAE 90.1 lighting power density limits, and daylighting best practices for tropical latitudes.NFPA 70E considered for arc-flash implications of major changes.In most cases, yes. Every kWh you can eliminate through efficiency is one you don't have to generate with solar — and efficiency retrofits typically have shorter paybacks than PV. On the reduced load, the solar system is smaller, cheaper, and offsets a higher percentage of consumption. Auditing first almost always improves the overall economics of the combined project.
The main exception: if solar is being driven primarily by resilience goals (backup during outages) rather than cost savings, efficiency work matters less and can happen in parallel.
Level 2 is our default recommendation for most facilities. It's detailed enough to make informed retrofit decisions without the cost of investment-grade rigor. Level 1 is worth considering only for small facilities or as a screening step. Level 3 is appropriate when the retrofit budget is large enough that the financing partner or board requires investment-grade documentation.
Depends on the level and the facility. A Level 1 walk-through can deliver findings within 1–2 weeks. A Level 2 for a mid-size commercial facility typically takes 4–6 weeks including data logging. Level 3 investment-grade studies with calibrated energy models can run 8–12 weeks.
Both. For electrical retrofits (lighting, controls, panel work, VFD additions), we typically handle both the engineering and installation under PE oversight. For HVAC, envelope, and specialty retrofits, we develop the construction documents and can manage contractor bidding and construction observation while the specialty trades execute the install.
Where available, yes. Puerto Rico's incentive landscape has shifted over time, so we'll research what's currently available for your specific measures and help with application documentation. We don't promise incentives that may not materialize — we quote projects with realistic economics whether the incentives come through or not.
Send us the basics about your facility — location, size, monthly consumption range — and we'll respond within one business day with a recommended audit level and a fixed-fee proposal.
