Maccari Energia / Distribution network design and utility approval
Distribution network design and utility approval
15, 25 and 35 kV networks, from routing to approved submission.
A land development waiting for network approval is capital standing still.
We design overhead and underground distribution networks in all three voltage classes and manage the process through utility approval.
Specialized experience
The team’s experience includes distribution-network analysis and design for RGE/CPFL, as well as Maccari’s own contracts. It includes three engineers, each with more than seven years of experience in 15, 25 and 35 kV networks.
The work covers land developments, overhead and underground networks, utility-outlet poles, pole-mounted substations, network extensions and technical support through approval.

Experience on the other side of the submission desk
Members of the technical team spent seven years at RGE reviewing projects. Their work included receiving submissions, checking compliance with utility standards and assessing them for approval or return with requirements.
That experience changes what leaves our office. The project is prepared in the format reviewers expect, with the details that commonly trigger requirements resolved before submission. This is not a promise of faster approval; it is the knowledge of a team with experience on the other side of the desk.
Featured topic
Approval
The drawing is rarely what holds a project up. Small deviations from utility standards can cause a rejection and send the process back by weeks.
We deliver the design in the required standard and follow the review to completion, responding to requirements as they arise. You do not have to mediate between the designer and the utility.

Frequently asked questions
DIRECT ANSWERS.
Yes. We work throughout Brazil and have delivered projects in RS, SC, PR, SP, MS and MG. Travel is itemized in the proposal.
Yes. Every project and report includes an ART issued in the responsible engineer’s name.
Most reports are delivered within 10 business days after inspection. Industrial facility projects take 10 to 20 business days depending on capacity, and network projects take 20 to 35 depending on the number of lots. The PIE takes 30 business days, while a power quality report takes 15 to 20 because it includes the seven-day PRODIST measurement campaign. Every proposal includes a firm delivery date.
Yes, if you want us to. The construction quote is presented later and separately from the design or report. You remain free to hire any contractor.
