We lead energy investments from concept to delivery
HELarch is not an ordinary design office — we are a partner who carries the investment from idea to delivery. Development, energy storage, PV farms, grid infrastructure, data centres and multidisciplinary design — in one team.
About us
A partner, not just a designer
HELarch is a design office specialising in the end-to-end development of energy and investment projects. We carry an investment through every stage of the process — from land acquisition and site analysis, through administrative decisions and grid-connection terms, to complete design documentation, construction supervision, acceptance and commissioning.
We work across renewable energy, battery energy storage (BESS), power grid infrastructure and data centre power supply. We complement this with multidisciplinary BIM design, Owner's Engineer support and transaction advisory with due diligence — so that a project is not only feasible, but bankable.
We work with investors, funds, independent power producers, local authorities and industry, providing full technical, formal and organisational support.
What we do
Our areas of work
Ten areas of expertise — from development and land acquisition, through the design of RES, energy storage and grid infrastructure, to supervision, acceptance and transaction advisory.
Energy Project Development
From concept to a ready-to-build investment
We develop energy projects end to end — from land acquisition, through administrative procedures and grid-connection terms, to Ready To Build (RTB) status. We manage the entire investment process, minimising risk and shortening delivery time.
Learn more→Energy Storage (BESS)
Stability and flexibility for modern power systems
We design small and utility-scale energy storage systems that support the energy transition. Our solutions improve grid security, increase the efficiency of RES installations and enable participation in the capacity market and ancillary services.
Learn more→Utility-Scale Solar Farms
Solar energy at industrial scale
We deliver photovoltaic farm projects from greenfield to commissioning. We combine design, technical and administrative expertise to create efficient, bankable projects for investors and funds.
Learn more→Power Grid Infrastructure
The foundation of reliable power supply
We design substations, cable lines and grid-connection infrastructure for RES, energy storage and industrial consumers. We ensure full integration of the investment with the national power system.
Learn more→Data Center & Power Infrastructure
Power for the digital economy
We support the development of data centres by designing power infrastructure and analysing the availability of grid-connection capacity. We create solutions that ensure highly reliable and secure power supply.
Learn more→Multidisciplinary Building Design (BIM)
Every discipline. One model. One goal.
We prepare comprehensive design documentation in BIM, integrating architecture, structure and building services. Digital coordination reduces the risk of errors and streamlines project delivery.
Learn more→EPC Support & Owner's Engineer
Investor support at every stage of delivery
We represent the investor's interests from the design phase through final acceptance and commissioning. We prepare technical and detailed designs, handle arrangements with grid operators and supervise project delivery.
Learn more→Transaction Advisory & Due Diligence
Secure investment decisions
We support the purchase, sale and financing of energy projects. We carry out technical, legal and commercial analyses, giving investors a complete picture of a project's potential and risks.
Learn more→Land & Investment Partner Sourcing
Connecting sites, capital and opportunities
We source land for energy investments and support the acquisition of investors and strategic partners. We help build projects that move successfully from concept to delivery.
Learn more→Energy Transition & Infrastructure of the Future
Designing tomorrow's solutions
We create solutions that answer the challenges of the future — from integrating RES and energy storage to infrastructure for industry, data centres and new technologies. We support clients in building modern, sustainable and resilient energy systems.

A partner who leads the investment — not just designs it
We combine development, design and engineering expertise: we acquire land, obtain decisions and grid-connection terms, design in BIM, and represent the investor on site and at acceptance. The investment moves smoothly from concept, through RTB status, to construction and commissioning (COD).
We work for investors, funds, IPPs, local authorities and industry — on RES projects, energy storage, power grid infrastructure and data centres.
- 10 areas of work — from development to acceptance
- RTB → COD we carry projects from greenfield to commissioning
- BIM multidisciplinary design in a single model
