Smart Strategies for Fleet Electrification

Tourmaline Advisors helps agencies, utilities, and fleets deliver electrification, covering strategy, infrastructure, and deployment.

Depot electrification is harder than it looks.

Most fleets underestimate what it takes to get a depot ready for electric vehicles. The grid may not have enough capacity. The utility process takes longer than expected. Charging strategy decisions made early have expensive consequences later. By the time an engineer starts drawing plans, the critical advisory work should already be done — and done right.

Tourmaline Advisors specializes in exactly that window: from the first grid assessment through utility approval, we give fleets and their partners the analysis and coordination they need to break ground with confidence.

Five steps to a fully electrified depot:

Is the site viable?

Before committing time or money, get a red/amber/green grid rating for your site using public utility capacity data. Fast, low-cost, and decision-ready.

What's the right approach?

Analyze your vehicles, duty cycles, and operations to model charging demand. Compare strategies and get a clear recommendation on how to electrify your depot.

What is the layout?

CAD drawings of your depot's civil layout and electrical single-line diagram — charger placement, panel and transformer sizing — ready to share with your utility and project partners.

How will you secure the power?

Work with your local utility's engineering team to get a formal study of the grid upgrades required to serve your depot load — with cost estimates and timeline.

How do you navigate the utility process?

We manage the full utility process — interconnection applications, Rule 15/16/29 filings, incentive & pilot program enrollment — so your project stays on schedule.

About Tourmaline Advisors

Andrew Papson has spent 20 years at the intersection of planning EV fleet deployments, designing electric charging depots, and connecting to grid power. He's learned that fleets can manage costs and accelerate timelines when technical design elements enter the planning process early. Tourmaline Advisors was built on that insight — helping fleets plan smarter, build lighter, and electrify faster.

We work with leading fleets, agencies and partners

Every EV depot starts with a plan. Let's build yours.
