Markets

Markets we serve

Energy Development

Tax equity, specifically the most prominent form (partnership flips), is a financing structure that involves the sharing of cash, tax credits, and losses between two partners in a partnership. The accounting is pretty complicated.  Orbis can walk your team through the commercial rationale for entering a partnership, apprise you of the trade-offs with other structures, and explain the modeling simply.

Infrastructure Finance

Working to finance public assets like toll roads, bridges, tunnels, airports, hospitals, or court houses? Orbis has deep expertise in the municipal and public private partnership spaces. We've built and audited some of the most complex models involving sophisticated investors on short timeframes. We can work with your team to build the value-for-money cases, or audit your model before bid submission.

Corporate Finance and FP&A

Running comps on public or private companies and need a model to run LBO scenarios? Have thousands of GL codes with monthly historical values running back years and need to build a trial balance and projection engine? Orbis has years of experience working with corporate dealmakers and the FP&A teams that make their investment dreams reality.

Portfolio modeling

One asset is tough enough; capex, financing during construction, operations, etc. What happens when you have multiple assets stacked in portfolio? "How do I think about creating structure at the HoldCo level?" "How do I ensure all my assets remain flexible and dynamic yet still standardized for aggregation?" Orbis has lots of experience with these types of questions. We're here to help.

WACC

January 30, 2026

Determining WACC in project finance goes beyond standard formulas—it’s about understanding real project risk. This article breaks down why corporate approaches often fall short and what truly drives the discount rate. A clear, practical guide to navigating uncertainty when key inputs like beta aren’t easily defined.

BESS development hinges on modeling dynamic, stochastic revenue streams—rather than relying on static assumptions—so developers can accurately value and optimize assets in volatile energy and ancillary markets.
