what this service is

An honest assessment of whether your project stacks up.

Most renewable energy advice comes from someone with a financial interest in the answer. Installers offer free feasibility studies because they want to win the install. PPA providers run free analysis because they want to fund the project. Arc charges for the work and answers to no contractor or counterparty.
A feasibility study from Arc tells you whether the project has a viable commercial case, what the right structure is, and what the right next step looks like. Including, when the evidence supports it, the answer that nothing should be built.
what we deliver

What we deliver.

Every feasibility engagement covers four core dimensions. We adjust scope and depth to the asset and the decision being made.
01

Energy yield modelling

Site-specific generation modelling using PVsyst or equivalent. Honest assumptions on irradiance, shading, soiling, and degradation. Output that can be defended at investment committee.
02

Financial returns

Payback, IRR, and NPV over twenty-five years. Multiple scenarios for capex, opex, energy prices, and counterparty assumptions. Written in the language of real estate investment, not engineering.
03

Grid & planning

DNO desktop review, capacity assessment, and planning risk identification. The two issues that derail commercial renewable projects more often than any other, surfaced before you commit.
04

Strategic options

Where the project sits within a wider asset or portfolio strategy. Phasing, sequencing, and the relationship to other decarbonisation initiatives in train.
why arc

Independence is structural, not stylistic.

Arc earns from the consultancy fee and nothing else. No commissions from contractors. No equipment kickbacks. No financial interest in any party we might subsequently introduce to you. The advice is shaped by what is right for your project and only by what is right for your project.
Our deliverables are written for fund managers, asset managers, and procurement teams, not for engineers. Structured, evidence-led, and defensible under audit.
Arc is regulated by RICS and certified to ISO 9001 and ISO 14001. That is the professional framework procurement-governed organisations require from a consultancy.
frequently asked

Questions clients ask before engaging.

Arc's feasibility studies start in the low four figures for a single smaller site and range to mid five figures for mid-market commercial or multi-site programmes. The fee reflects the depth of analysis. We do not offer free feasibility as a sales tool to win the next contract.
Two to three weeks from instruction for a single site. Larger portfolio reviews take longer, typically four to eight weeks depending on the number of sites and the data available.
No. The independence that makes the advice worth having means we will tell you when the answer is that the project should not be built, or should be deferred, or should be restructured. The fee buys an honest answer.
If the project has a viable case, Arc can continue into procurement and project delivery. If it does not, we tell you. If a different consultancy is the right next step, we make the referral.
