Project Turtle: Investment in Solar Energy and Storage (BESS) in Romania
The renewable energy market in Europe continues to evolve towards more efficient, flexible, and sustainable models. In this context, projects that combine solar photovoltaic (PV) energy and battery energy storage systems (BESS) have emerged as one of the main investment opportunities in energy infrastructure.
Within this trend, Tartessos Power Development has launched Project Turtle, a utility-scale portfolio in Romania that integrates solar generation and energy storage, offering a strategic opportunity for investors in the energy sector.
Project Turtle: A Hybrid PV + BESS Portfolio in Romania
Project Turtle consists of two key assets within the solar energy and storage market in Romania:
NEAMT Project (Hybrid PV + BESS)
- 58 MWp photovoltaic capacity
- 49 MW / 193 MWh co-located energy storage (BESS)
Câmpia Turzii Project (Standalone BESS)
- 48.5 MW / 95.3 MWh storage capacity
This hybrid approach combines large-scale solar energy generation with storage solutions, enabling more efficient energy management and greater grid stability.
PV+BESS projects are gaining momentum across Europe due to their ability to enhance renewable integration and participate in energy flexibility markets.
Advantages of Energy Storage (BESS) in Solar Projects
Battery energy storage systems (BESS) are key to the development of modern energy systems. In the case of Project Turtle, their integration provides multiple benefits:
- Optimization of generated energy usage
- Reduced dependence on solar conditions
- Participation in balancing markets and ancillary services
- Improved grid stability and resilience
The combination of solar + BESS in Romania positions these projects as strategic assets within the European energy transition.
Competitive Advantages: Costs, Design, and Grid Connection
One of Project Turtle’s key differentiators is its technically and economically optimized design.
The NEAMT project features a co-located configuration that reduces EPC (Engineering, Procurement, and Construction) costs, thanks to a compact infrastructure integrating generation and storage at a single site.
Key advantages include:
- On-site substation, reducing technical complexity
- 110 kV high-voltage line crossing the site
- Competitive grid connection costs of approximately €47,800/MWp
The Câmpia Turzii project also presents favorable conditions:
- Grid connection costs of approximately €40,800/MWac
- Connection distance of only 1.9 km
These characteristics position the portfolio as a highly competitive option in the renewable energy investment market in Eastern Europe.
Development Status and Timeline (COD)
Project Turtle stands out for its advanced development stage, significantly reducing risk compared to early-stage projects.
NEAMT:
- Grid connection permit (ATR) obtained in 2025
- Advanced technical approvals (CTE approval)
- Construction permits expected in Q4 2026
- Commercial Operation Date (COD) estimated in Q4 2027
Câmpia Turzii:
- ATR expected in Q2 2026
- COD estimated in Q3 2028
This level of progress makes Project Turtle a compelling investment opportunity in solar and BESS with clear execution visibility.
Project Security: Long-Term Agreements
Both assets benefit from 35-year land lease agreements, ensuring land-use stability and long-term legal security.
This type of structure is highly valued by infrastructure investors, as it supports predictable cash flows and reduces operational uncertainty.
Investment Process for Project Turtle
The sale process is being managed by Blu Capital Partners Energy & Infrastructure Advisory, a financial advisor specialized in energy and infrastructure transactions.
The timeline includes:
- Non-binding offers: March 2026
- Data room: April 2026
- Binding offers: May 2026
- Expected closing: May 2026
The project is targeted at institutional investors, infrastructure funds, and strategic partners interested in renewable energy assets with storage.
Tartessos Power Development: Expertise in Renewables and BESS
Tartessos Power Development is a developer specialized in solar energy and battery storage (BESS), with a presence in Spain, Germany, and Romania.

- A Romanian portfolio of 150 MW PV and 600 MWh BESS
Renewable Energy Investment in Romania: A Growing Opportunity
Romania is positioning itself as one of the most attractive emerging markets for renewable energy investment in Europe, driven by:
- Growing electricity demand
- Need for grid modernization
- Support for the energy transition
- Development of flexibility markets
In this context, projects integrating solar PV and BESS offer a clear competitive advantage over traditional assets.
A Strategic Solar and Storage Project
Project Turtle represents a unique opportunity for investors interested in the European energy sector, combining:
- Solar generation and energy storage
- Optimized design and competitive costs
- Advanced development stage
- Strong developer track record
With the sale process already underway, the project is aligned with key market trends: solar energy, battery storage (BESS), and energy transition.
