The duration of an energy audit depends on the scope and depth of analysis.

Typical timelines:

• Preliminary / walk-through audit: 1–2 weeks
• Detailed energy audit (ISO 50002 / ASHRAE Level II): 4–8 weeks
• Investment-grade audit (complex facilities): 8–12 weeks

This includes:

• Data collection and site measurements
• Analysis and modelling
• Identification of opportunities
• Financial evaluation
• Drafting and validation of the final report

Larger industrial sites or multi-facility audits may require longer timelines.

Yes, a written report is given to the client upon the completion of the project. The report contains an executive summary and a table of findings that show important audit findings and recommendations. The list of recommendations contains implementation cost estimates, energy and cost savings.

The cost of ISO 50001 certification in Nigeria depends on facility size, complexity, and readiness.

Costs generally fall into three components:

1. Implementation & consulting support
2. Certification audit by an accredited body
3. Internal resources and data preparation

Typical cost ranges (indicative):

• Small–medium facilities: ₦10m – ₦20m
• Large industrial or multi-site organisations: ₦20m – ₦40m+

These costs usually cover:

• Energy review and baseline development
• EnPIs and action plans
• Staff training and documentation
• Internal audit and management review support
• External certification audit

ISO 50001 certification is typically valid for 3 years, with annual surveillance audits.

Batteries are not required for all solar systems but they are needed for power backup. Solar panels make power when they are exposed to sunlight, therefore, this means that you won’t have power (‘light’) at night from your solar power system without batteries. 

A carbon project is an activity that reduces, avoids, or removes greenhouse gas (GHG) emissions compared to a defined baseline scenario, and can potentially generate carbon credits under recognised standards.

Examples include:

• Diesel-to-solar or hybrid energy transitions
• Energy efficiency improvements
• Methane capture

To be creditable, a carbon project must meet strict technical and governance requirements, not just reduce emissions in practice.

MRV stands for Monitoring, Reporting, and Verification.

It is the system that ensures:

• Emissions data is accurately measured
• Reductions are transparently reported
• Results are independently verified by accredited bodies

MRV is the backbone of credible carbon projects and is mandatory under all recognised standards.

Ecowatt supports clients by:

• Assessing carbon project eligibility and risks

• Designing MRV frameworks aligned with international standards

• Preparing validation- and verification-ready documentation

• Supporting engagement with accredited VVBs

• Ensuring defensible, audit-ready emissions data

• Aligning carbon projects with broader climate and financing strategies

No. Not all projects qualify. Common reasons projects fail include:

• Lack of additionality

• Weak baseline justification

• Poor data quality

• Regulatory requirements already mandating the activity

• Insufficient scale or monitoring capability.

A carbon readiness assessment is often required before proceeding.
