How much energy
is lost.
Round-trip efficiency relates the energy that goes into the system to the energy that comes out.
Utility-scale · On the owner's side
A battery
is not a solar power plant.
Use, warranty and future capacity are decided from the outset. We work alongside you from feasibility to plant acceptance: the battery on its own, the battery and the solar plant built together, or the battery added to a plant that already exists.
What you are hiring: your engineering on the owner's side, in phases. From deciding whether the project goes ahead to accepting the plant, and each phase is agreed separately.
Explore the four phases
A concept. An operating asset.
Four phases.
Your point of entry.
Each phase, and even each part within it, can be contracted separately.
01
Go or no go.
The risk
Developing the wrong project.
What we do
We compare options and size the battery for your dispatch, climate and project parameters.
You get
Recommended configuration, a go or no-go recommendation and the inputs for your financial model.
See the scope of this phase
Sizing uses our degradation model. The recommendation is tied to the planned use and the project assumptions.
The model, inside the study
Your cell.
Your site.
Your use.
The manufacturer's curve is usually reasonable for a generic use. Our model calculates the one for the specific project and relates it to the warranty.

- StudyDegradation and warranty conditions.
- DecisionMargin, future capacity (augmentation) and written assumptions.
We do not sell an application. The model is the tool we do engineering with.
Two different questions
Efficiency is not
capacity.
How much energy
How much energy
it can hold.
Capacity changes with calendar and cycling ageing. It is studied together with the planned use.
They are two different quantities. An offer should treat each one with its own definition and its own measurement.
Other ways to start
Is your project
already under way?
I have a solar plant, or I am about to build one, and want batteries
We size the battery on the plant that already exists, or alongside the one you are about to build: what use suits it, how much to add, how it ages and what changes in the contract and the grid connection.
I already have a contract or a warranty
We review supply agreements, technical schedules and owner's requirements as a standalone assignment.
I am going to buy an operating asset
We study its condition, the remaining warranty cover and the capacity that may need to be added.
My team is new to storage
Talks and courses on ageing, warranties, contracts, construction and acceptance testing.
For locally licensed engineering, financial modelling, logistics, factory testing and fire safety we work with partners.
How we charge.
Studies have a fixed price per project. Construction and commissioning support is priced per MWh, not as a percentage of CAPEX, so our fees do not rise when equipment gets more expensive. Figures go in a proposal, for the specific project.
The next step
Let's start with
one project.
A one-hour technical discussion with your team, about a solar plant you want to hybridize or an asset you are about to buy. No cost, no commitment.
