Strategic Energy Advisory & Project Development
GFD strengthens strategic energy capability through partnership with Sonas Energy
Green Forty Development Limited (GFD) has strengthened its long-standing partnership with Sonas Energy, combining strategic energy planning, techno-economic modelling and practical project development to help clients move from concept to operational renewable energy infrastructure.
The partnership builds on successful work across Buchan Biogas, Project Alba—Scottish Enterprise’s green hydrogen from biomethane research programme—and the Blackparks Anaerobic Digestion feasibility study near Stranraer.
Together, GFD and Sonas Energy now offer an integrated service across the full project lifecycle.
From Strategy to Delivery
Our whole-system approach identifies the right blend of technologies, infrastructure and commercial models, including:
- Biomethane and Anaerobic Digestion
- Green hydrogen production and utilisation
- Solar PV generation
- Battery Energy Storage Systems (BESS)
- Electrification of heat
- Heat networks
- Transport electrification
- Smart microgrids
- Demand-side management
- Energy storage
- Grid connection strategy
- Energy market optimisation
- Power Purchase Agreements (PPAs)
- Biomethane Purchase Agreements (BPAs)
We model how these elements interact to improve performance, reduce cost and strengthen long-term returns.
Creating Investable Energy Systems
By combining GFD’s project development expertise with Sonas Energy’s strategic planning capability, the partnership goes beyond conventional consultancy.

Supporting Public and Private Sector Clients
The combined capability supports local authorities, developers, industrial and commercial clients, landowners and public sector organisations seeking practical pathways to net zero.
From regeneration projects and industrial facilities to mixed-use developments, the focus is consistent: linking demand, generation, storage and infrastructure to create commercially viable, financeable energy systems.
By combining advisory and project development expertise, GFD helps turn ambitious net zero objectives into investable, deliverable renewable energy projects.
