Generate
Wind speed or irradiance becomes electrical energy at each unit. Unit rating and capacity factor decide how many machines a target actually needs.
Digital modelling · interactive
See how energy products are built, and how every megawatt travels.
A wind farm asked to deliver a set number of megawatts implies a specific number of turbines, a specific footprint, a conversion chain, a storage decision and a wheeling arrangement. This page lets you change the inputs and watch the whole path respond.
The modelling studio
Set the target. See the plant it takes to get there.
Choose a product, set the megawatts you need and watch the model resolve equipment counts, conversion, storage and the wheeled path to the offtaker.
Inputs
Turbines convert moving air into rotational torque, then into three-phase AC at the nacelle generator before being stepped up for the grid.

Generate · convert · store · wheel
Four steps between a resource and an offtaker.
02
Convert
Converters and transformers lift plant voltage to collector and transmission level. Every step costs a small percentage of the energy produced.
03
Store
Batteries move energy out of the surplus hours and into the peak, at a known round-trip efficiency and a known container count.
04
Wheel
Energy is injected at the plant and drawn by an offtaker elsewhere on the network, settled against use-of-system charges and network losses.
Who this is for
Built for the people who have to decide.
We build these models to your project — your resource data, your grid connection, your offtake and tariff structure — as an interactive digital twin alongside the physical model.
- Developers & IPPs
- Test layout, turbine selection and storage duration before committing to a grid application or a full financial model.
- Offtakers & corporates
- See what a wheeled supply agreement means in plant terms — capacity, shape, losses and the charges that sit between the two meters.
- Boards & communities
- One shared picture of how the project works, from resource to socket, in language everyone in the room can follow.
