Engineering and permitting: from the point of connection to the construction drawing.
Project design, grid connection, permitting and technical documentation. We support each project from the earliest grid access and connection stages through to detailed engineering.
Estimated availability
>98.9%
In 99% of simulated scenarios (PERT studies). Indicative figure per project.
Short circuit
IEC 60909
Energy storage
IEC 62933
How we work
Five stages, one consistent file.
Each stage feeds the next: data from the grid access study flows intact into the tender drawings and the operating manuals.
- 01
Grid access, connection and permitting
We coordinate technical requirements with distribution companies and regulators and manage the permitting process through to final authorisation, without delays and fully grid-compatible.
Deliverables
- Grid access and connection application
- Separate filings for public bodies
- Application tracking
- 02
Sizing and design
We size the plant, select the equipment and design the complete electrical configuration: layout, cabling, cable ducts and structures. An efficient, safe and scalable design.
Deliverables
- Layout and electrical configuration
- Equipment selection
- Energy balance
- 03
Bid engineering
Electrical, mechanical and civil drawings ready for tender, analysis of expected energy yield, and cost and profitability assessment so you can decide on a solid basis.
Deliverables
- Tender drawings
- BOM and quantities
- Profitability report
- 04
Availability studies
MTBF, MTTF and PERT models to estimate the installation's operational availability. In our studies we estimate availability above 98.9% in 99% of scenarios.
Deliverables
- MTBF / MTTF analysis
- PERT simulation
- Spare parts plan
- 05
Detailed engineering
Civil works calculations, single-line diagrams, earthing and short-circuit studies to IEC 60909, with documentation and manuals that make construction and operation easier.
Deliverables
- Single-line diagrams and earthing
- Short circuit IEC 60909
- O&M manuals
Hybridisation permitting
Adding batteries to a solar plant has its own path.
Since RD 917/2025, a plant under the specific remuneration regime can be hybridised without losing its remuneration. What changes is the application file, depending on the asset's stage.
Plants at RtB
- Grid access and connection updates
- Hybridisation application
- Point of consumption
- Simplified EIA
- Guarantees and licences
Plants at COD with capacity increase and energy storage
- Permitting for an RtB plant
- Land-use review
Plants at COD
- Engineering and permitting
- Installation and commissioning
- Control with EMS and PPC
