AShared value
Projects that bring value to every stakeholder
We develop projects that create value for local communities, partners, clients and investors — not just for the group.
Critical infrastructure development group
We build the energy and computing power that regions depend on.
450ppm Développement designs, finances and operates renewable energy and computing assets — from land sourcing to commissioning, with a long-term infrastructure approach.

01 The Group
Infrastructure carries a name, not a slogan.
450ppm refers to the atmospheric CO2 concentration threshold associated with lasting climate disruption. It is the name we chose for a group whose ambition is to develop, at regional scale, the energy and computing infrastructure the transition requires — and to sustain it over time.
We work across the entire value chain: land identification, development, permitting, financing, construction and operation. Our assets are designed as critical infrastructure: essential, durable, and built to remain operational for decades.
[01] Sovereignty
Assets rooted in their regions
Physical and digital infrastructure developed and operated locally, in support of energy and digital independence.
[02] Long term
Assets held, not flipped
The group develops and operates its assets over the long term, with an infrastructure mindset rather than a project mindset.
[03] Integrated execution
From development to operation
A single team steers each asset from land sourcing to commissioning, and then through its operation.
02 What we bring
An operator that takes on the operating risk for you.
We develop infrastructure projects that create value for all stakeholders, while carrying the execution risk ourselves.
BSolution engineering
Answers to complex operational challenges
We build solutions by designing infrastructure-type projects that address complex operational challenges, particularly around decarbonisation and technological sovereignty.
CEnd-to-end structuring
Partners, operating model, financing, development
We find the partners, design the operating and financing model, and develop the project on behalf of our clients.
DProximity and trust
An operator that carries the operating risk
We are close, trusted operators who take the time needed to shoulder the operating risk on your behalf.
03 Our business divisions
Two divisions, one critical infrastructure mindset.
The group organises its activities around two complementary divisions — energy and digital infrastructure — developed with the same standard of execution.
Energy Division
Energy generation and storage
Development of energy generation and storage projects, combining industrial biomass and renewable electricity.
BIOMASS
Industrial biomass
Generation and sale of energy from industrial biomass, connected to local resources and distribution networks.
PV
Solar
Development of renewable electricity projects, notably ground-mounted photovoltaic plants: land identification, permitting, grid connection, construction and operation.
BESS
Battery storage
Development of stationary battery storage sites, for grid balancing and to maximise the value of the energy produced.
IT Division
Sovereign digital infrastructure
Development of critical digital infrastructure: telecommunication networks, data exchange and computing for artificial intelligence.
5G
Sovereign 5G networks
Development of 5G telecommunication networks built on a sovereign technology component.
DATA
Data exchange infrastructure
Development of data exchange infrastructure, notably for French agricultural data, through Netframe and Agdatahub.
AI
AI data centers
Design of small-capacity data centers, located as close as possible to energy generation sites, dedicated to artificial intelligence computing.
04 Partners and clients
They trust us.
The group develops its projects alongside industrial companies, operators and institutions committed to energy and digital technology.
