Plans
Two paths to a better grid design.
Whether you need a fully managed engineering engagement or want to build long-term optimisation capability in-house, Rezo delivers faster, more defensible grid designs and the confidence to back them.

How We Work
Expert-led engagement or self-serve platform. Both powered by Rezo.
Rezo is available as a fully managed engineering engagement or as a self-serve web platform. Both deliver the same optimisation engine. The difference is who runs it.
Expert-Led Engineering
Leverage the deep offshore grid experience of our team, who have delivered some of the largest offshore wind projects for over 15 years. Rezo engineers run the optimisation and deliver ready-to-implement designs, perfect for single projects or quick wins.
Cloud-based optimisation platform
Direct access to Rezo's full optimisation engine. Run unlimited scenarios, collaborate across teams, and build long-term capability in-house to make faster, more competitive, and robust design decisions with full control of your grid designs.
Expert-Led Engineering
The full power of Rezo, delivered by the team that built it.
Our engineers have delivered grid connection designs on some of the largest offshore wind projects built over the past 15 years. When you engage us, that experience is applied directly to your project, with Rezo running the optimisation and our team interpreting the results in the context of your specific constraints, stakeholders and timeline.
Ready-to-implement designs
We deliver optimised, defensible grid designs, not just outputs. Every recommendation is grounded in both the optimisation and practical engineering judgement.
Single project or framework engagement
Ideal for a specific design challenge, a competitive tender or an ongoing framework where you need expert support across multiple projects.
Full capability access
Every Rezo capability is available, from substation location and lifecycle optimisation to sensitivity analysis, applied to your project by engineers who use it every day.
Cloud-Based Platform
Full optimisation capability.
Your team. Your projects. Your pace.
Rezo is available as a web-based platform, accessible from anywhere, with no installation required. Run unlimited scenarios, import your project data and explore the full design space at the pace your project demands.
Unlimited simulations
No per-run limits. Explore as many scenarios as your project requires, from rapid early-stage screening to detailed design validation.
Built for collaboration
Share results across disciplines, compare scenarios side by side and keep the full project team aligned on a single set of numbers.
Start fast, go deep
Pre-built templates and a curated cable library get you up and running immediately. Adapt them to your project and save your own for future use.
Full capability access
Lifecycle cost optimisation, intelligent route finding, cable design and selection, substation location and sensitivity analysis, all in one platform.

Learn More
New to Rezo? Start with the overview.
If you are still exploring what Rezo can do for your project, the links below are the best place to start.
Rezo Overview
Find out what Rezo is, how the software works and who it is for. The Overview page is the best starting point if you are new to the platform.
Lifecycle Cost Optimisation
Understand why the cheapest cable design is rarely the most cost-effective one, and how optimising for the project lifetime routinely delivers savings in the millions.
Substation Location
Learn why the substation position is the most consequential decision in the grid connection design, and how you can determine the optimal position for your project.
Sensitivity Analysis
Discover how to stress-test your offshore grid connection design against uncertain inputs and quantify the cost of being wrong before you commit.
FAQs
Everything you need to know about Rezo. Can’t find the answer you’re looking for? Please reach out to our team.
What is the difference between Expert-Led Engineering and the web application?
With Expert-Led Engineering, our team runs the optimisation and delivers ready-to-implement designs for your project. The web application gives your team direct access to Rezo's full optimisation engine, so you can run scenarios, explore the design space and build in-house capability at your own pace. Both options use the same underlying technology.
Can I switch from Expert-Led Engineering to the platform over time?
Yes. Many clients start with an Expert-Led engagement to get results quickly and build familiarity with Rezo, then transition to the platform as they build in-house capability. We support that transition and can provide training and onboarding to help your team get up to speed.
What data do I need to get started?
You need a turbine layout and a connection point. Pre-built templates and a curated cable library are included in the platform to get you started immediately, even before all project data is available.
How long does a typical optimisation run take?
Most optimisation runs complete in minutes.
Is my project data secure?
Yes. Rezo is built on secure cloud infrastructure and your project data is never shared with third parties. Contact us if you have specific data security or confidentiality requirements.
How much can Rezo reduce cable lengths and costs?
By optimising grid connection components, Rezo can typically reduce cable lengths by up to 20%, significantly cutting project lifecycle costs and minimising the environmental impact of the cable system.
Can you guarantee us cost savings?
While we have seen multi-million euro savings on all projects up to now, we offer a free assessment of the optimisation potential to clients before starting a project to assess possible cost reductions.
Do you only optimise offshore wind farm grid connections?
Our main focus is offshore wind farms due to the scale and complexity of these projects. However, our algorithms can be applied to various problems such as large-scale solar PV plants, combined offshore wind and solar plants, and electrical charging infrastructure.
Who can benefit from using Rezo?
Rezo is designed for offshore wind developers, transmission system operators, engineering firms and EPCI contractors who want faster, more defensible grid connection designs. If you are involved in the design, procurement or delivery of an offshore wind grid connection, Rezo is relevant to your work.
How can I learn more about Rezo?
The best starting point is the Rezo overview page. You can also request a demo or contact our team directly.
