Why do businesses need energy storage today?

The electricity market is becoming unstable – fluctuating prices, increasing grid fees and high energy security requirements. BESS battery systems help control costs and reduce risks.

High Electricity Costs

Volatile exchange prices and peak hours increase bills. With BESS, you can charge batteries when electricity is cheaper and use stored energy during expensive hours.

Peak Loads and Power Limitations

In production and warehouse facilities, short-term peaks create additional costs or require expensive grid capacity increases. BESS balances peaks and reduces required connection capacity.

Ensuring Continuous Operation

IT infrastructure, production lines and security systems cannot stop even during brief interruptions. BESS provides automatic transition to battery power for critical equipment.

Untapped Earning Potential

BESS allows participation in balancing and flexibility markets, receiving compensation for grid stabilization if the system and connection support it.

What is BESS – Battery Energy Storage System?

BESS or Battery Energy Storage System is an industrial battery installation that stores electrical energy and delivers it when most cost-effective or critical. The system can charge from the grid, solar or wind power plants and provide energy even when generation stops or the grid is unavailable.

Modern BESS installations are containerized or cabinet-integrated systems that include battery modules, inverters, control systems, cooling and safety solutions. They are designed for continuous operation in industrial conditions.

Where does BESS provide the greatest benefit?

BESS solutions are suitable for businesses across various sectors – from manufacturing and logistics to energy and municipalities.

Manufacturing Companies

Load balancing, peak reduction, backup power for lines and ability to optimize grid capacity.

Warehouses and Logistics Centers

Electric vehicle and equipment charging, refrigeration, lighting – BESS helps control power peaks and thus electricity costs.

Solar and Wind Farms

Hybrid farms with BESS ensure more stable generation, better predictability and opportunity to participate in balancing markets.

Data Centers and IT Infrastructure

In addition to UPS level, BESS provides longer backup power, reduces need for diesel generators and allows more flexible load planning.

Shopping Centers and Office Buildings

Combining BESS with solar panels can reduce total energy costs and increase building energy efficiency.

Municipalities and Utility Companies

Street lighting, heating substations, pumping stations and other critical facilities – BESS provides safe and efficient energy reserve.

BESS Together with Solar Power Plant – Smart Energy Management

BESS ideally complements solar and wind power plants. During the day, batteries store cheap and self-generated energy, and in the evening and night use it at the facility or sell to the grid according to market situation.

Hybrid solutions help reduce grid load, improve generation predictability and increase project returns. As a result, the company receives not only green energy, but also a more stable and predictable electricity cost level.

Financial Benefits for Business

A BESS project is not just technology – it is a financial solution that affects the company’s cost structure and revenue potential.

Lower Electricity Costs

By optimizing electricity consumption throughout the day, it is possible to reduce both exchange and grid fees. BESS allows shifting consumption to cheaper hours.

Peak Load Reduction

Required connection capacity and associated costs are reduced. This is especially important for production and logistics facilities.

Additional Revenue from Markets

Subject to connection and regulatory requirements, BESS can be used in balancing and flexibility markets, receiving compensation for grid stabilization.

Lower Energy Losses and Cost Risks

The storage system reduces losses that occur when producing and delivering electricity during cheapest hours and consuming it during most expensive. You charge batteries when energy is cheap or not profitable to deliver to the grid, and discharge – at financially most favorable moments. This solution is especially suitable for both power generation stations and industrial consumers who want to reduce cost fluctuations and stabilize their energy balance.

Why Choose SIA TESLA as Your BESS Partner?

SIA TESLA is a Latvian company with experience in designing and building solar power plants, electrical distribution, automation and energy storage solutions. We understand both technical and regulatory requirements in the Latvian and Baltic markets.
We work as an integrator – we help choose the most suitable BESS technology, perform load and connection analysis, prepare technical project, organize delivery, installation and commissioning.

Frequently Asked Questions

How long does BESS project implementation usually take?

Depending on project power and complexity, BESS implementation usually takes 4 to 9 months – including research, design, equipment delivery, installation and commissioning.

What are the connection requirements?

Requirements are determined by the specific distribution or transmission system operator and facility’s electrical infrastructure. At project start we perform load and connection analysis to determine optimal solution and coordinate with operator.

Can BESS be combined with existing solar power plant?

Yes. BESS can be added to existing solar power plant to increase self-consumption, reduce energy delivered to grid when price is low, and provide backup power.

How is BESS maintained and monitored?

System is equipped with monitoring and remote supervision tools. We offer service contracts that include regular inspections, software updates and alarm response.

Is financing available for BESS projects?

It is possible to attract bank financing and in some cases – support instruments. We help prepare technical and financial documentation for negotiations with financiers. ALTUM co-financing up to 95% of project costs and capital discount up to 30% is possible by timely applying for the project and meeting ALTUM conditions.
