The importance of sustainable power

At SieStar we understand the importance of sustainable power for businesses. The investment in renewable energy is not just a step in the right direction towards a smaller carbon footprint, but also offers economic advantages such as lower energy costs and a more stable power supply. Sustainable power makes you a competitive player on the market by using innovative, reliable energy solutions. With our integral approach of smart energy storage and management, we contribute to an emission-free future and help your company grow with a sustainable and efficient power supply.

The challenges of the transition period

Despite your progressive steps toward renewable energy, limitations in the electricity grid can cause your systems to underperform or prevent you from fully benefiting from your investments. Grid congestion entails that the capacity of the grid is not always sufficient to efficiently transport the generated energy, which may lead to inefficiencies and wasted energy.

This situation highlights the need for advanced solutions that can optimize your energy infrastructure and ensure that your sustainable initiatives deliver real returns. At SieStar, we help you tackle this challenge with innovative solutions that provide a reliable and efficient energy supply.

Peak Shaving

Our systems provide the opportunity to use your power efficiently. Peak shaving entails that you store energy during periods of low demand and therefore save for later use during moments of peak demand. By implementing this strategy, you can spread your energy consumption and avoid relying on the grid during peak demand, when it may not be able to effectively support your systems.

Load Shifting

Our systems enable you to optimize your energy consumption by means of load shifting. Load shifting means that you shift your energy consumption from peak hours to periods of lower demand. By scheduling your high energy processes to moments of lower demand, you are able to prevent pressure on the grid and lower your energy costs. This strategy ensures that you not only benefit from lower rates but also reduce the congestion on the grid. With load shifting you can optimize your energy consumption, reduce costs and improve the reliability of your power supply.

Energy market trading

SieStar smart energy storage solutions offer the opportunity to buy and sell electricity on the market. Store energy from green power or even buy it at very low to negative prices, and feed it back to the grid when tariffs are highest. You can trade on different markets such as the imbalance market and the intra-day market. With this lucrative revenue model, companies can actively help reduce fluctuations in the energy market.

Energy buffer

At SieStar, our smart energy storage solutions provide the opportunity to store excess energy during periods of low demand and release it when demand rises. This results in significant cost savings and a reliable power supply. By strategically managing energy, you can not only benefit from an efficient power supply but also contribute to a stable energy market. Discover how our solutions can help your business achieve optimal energy management and save costs.

Shore power supply

SieStar’s smart energy system provides an advanced solution for shore power supply, enabling ships to be efficiently powered while docked. Our system ensures a reliable and secure connection, allowing ships to not use their diesel generators. This not only reduces the emission of harmful substances but also reduces noise, all while contributing to lowering operational costs and a cleaner environment.

Emergency power supply

For critical processes, you can reserve a portion of the energy storage as an emergency power supply through the EMS. After disconnecting from the grid, critical users can temporarily be powered manually. The SieStar energy storage system can be used as a fully functional uninterrupted power supply (UPS), with the integration of an automatic Switch module.

Optimization energy contract

SieStar provides advanced solutions for optimizing your energy contract. By monitoring your energy storage and usage, you can align your contract with your actual energy needs and benefit from lower rates. We analyze your energy usage, efficiently manage demand and supply and advise about contract optimization, because of this you can save costs and optimize your energy supply.

Power supply at emission-free construction sites

SieStar's smart energy solutions enable emission-free power supply on construction sites. By using renewable energy sources and storage systems, you can build without polluting diesel generators. This reduces emissions, provides quiet energy and complies with environmental regulations. Find out how we can make your projects more sustainable and efficient.

Applications

Construction site

Challenges on construction sites include inadequate energy connections (3*80A) for charging electric vehicles and meeting strict emission standards. SieStar's battery energy storage system offers the solution: peak shaving to cope with peak consumption, load shifting to use generated energy later, and mobile storage for emission-free energy supply.

Transport & Logistics

In the case of intensive charging at logistics centres, the contracted transport capacity (CTC) is often not sufficient. SieStar's energy storage system with EMS enables fast charging without exceeding the CTC, stores self-generated energy, and offers flexible charging solutions for transport equipment.

Manufacturing companies

Increasing investments in renewable energy are pushing networks to their limits. SieStar's smart energy storage provides peak shaving and load shifting to reduce peaks and costs. Excess energy can be stored, optimized and possibly traded, so that companies can continue their processes without grid reinforcement.

Port operators

Port operators can reduce CO₂ emissions and noise by offering ships shore-based power. SieStar's battery storage helps to cope with peak consumption and grid congestion, is mobile and ensures stability in variable consumption, so that sustainability and electrification of port activities can run smoothly.

SME

Energy transition leads to additional load on business connections. SieStar's storage reduces peak load and energy costs with peak shaving and optimises own energy via load shifting. The EMS provides emergency power and a buffer for business continuity, without waiting for grid reinforcement.
