Whether you are a developer, investor, asset manager or buyer, we offer high quality services and expertise.
- Technical-economic feasibility study
- Site assessment: Grid connection, planning and lease agreements
- Management/PM development phase: permitting / connection management
- Energy performance assessment
- Grid impact assessment using specialised software
- Preliminary engineering and simulations
- Techno-economic and cost-effectiveness reassessment based on key performance indicators
- We act as Tender Agents
- We are experts in project financial modelling

2. CONSTRUCTION PHASE
Detailed engineering and support
We carry out detailed engineering for all types of battery projects. We provide both technical and contractual support throughout the process with clients and suppliers.
We carry out exhaustive technical-economic studies that guarantee the good performance of the installation.
- Owner’s representative/PM during construction
- Tender management / procurement process
- Review of bids and technology
- Support in contractor/EPC selection
- Factory Acceptance Tests (FATs) and Site Acceptance Tests (SATs)

3. POST-CONSTRUCTION PHASE
Performance and optimisation
We take care of studying the performance of the installation and its efficiency. We evaluate the operational performance of the system according to the agreed O&M standards and propose improvements for system optimisation. We also check performance compliance according to the network operator’s terms.

- Dynamic performance
- Isolation studies
Frequent business models in battery energy storage systems / BESS
BESS systems (Battery Energy Storage Systems) allow energy to be stored for later consumption. Coupled to the general electricity grid or renewable sources of electricity production, they can supply clean energy at times of zero generation.
ARBITRAGE
Energy is bought and stored when prices and demand are low and then sold during periods of high demand and higher prices, achieving high profitability.
ELECTRICITY SYSTEM REGULATION
The stored energy supports the general power grid so that the supply is secured and the frequency of the grid is maintained.
RENEWABLE STORAGE
Coupled with renewable energy sources, they make it possible to store surplus energy, resolving the intermittency of production.
CAPACITY RESERVES
The storage system makes it possible to supply energy to the general grid in unexpected situations in which the production system does not supply energy. This increases the capacity of the electricity grid and ensures supply in times of emergency.
TRANSMISSION UPGRADE DEFERRAL
Transmission upgrade deferral involves delaying investments in transmission system upgrades by using relatively small amounts of storage or, in some cases, avoiding such investments altogether. This storage compensates for overloading and ageing.
TRANSMISSION CONGESTION RELIEF
Congestion occurs when the energy produced cannot be delivered to loads due to inadequate transmission infrastructure. Electricity storage can serve to avoid congestion-related costs and charges, especially if costs become onerous due to significant congestion on the transmission system.
BLACK START
BESS can provide power for the energisation of transmission and distribution lines, for the activation of power plants during start-up or in case of grid collapse.
OTHERS
There are other applications for BESS that make it a highly attractive technology, such as improving power quality or end-user autonomy.
Whether you are a promoter or developer of BESS projects or a consumer looking to offer services to the grid, hybridise a renewable production plant or are looking for arbitration services or to flatten your consumption curve, Cobaltiq is your solution. We are expert consultants in the large-scale implementation of BESS systems, we study your project and its feasibility and we propose the best alternative according to your needs and profitability.
