Three years ago, SCU deployed the country’s first 40ft containerized energy storage system at a solar farm in Bulgaria, setting a precedent for large-scale industrial and commercial energy storage. Now, three years later, how is this system running? What value has it brought to customers? This article will take you to find out.
1. The milestone significance of the first 40ft container energy storage
As the first 40ft container energy storage project in Bulgaria, SCU has demonstrated its leading position in the field of large-scale commercial and industrial energy storage with its strength. Over the past three years, the system has accumulated more than 10,000 charging and discharging times, bringing direct economic benefits of more than 350,000 euros to customers. The success of this project has not only won SCU a good reputation in the industry but also set a benchmark for the development of renewable energy in Bulgaria.
2. Project background: Solving PV curtailment and power rationing, empowering solar farms
As an important market for the development of renewable energy in Europe, Bulgaria has seen rapid growth in photovoltaic installed capacity in recent years. However, with the increase in the proportion of photovoltaic power generation, the problem of grid stability has become increasingly prominent, and the phenomenon of photovoltaic curtailment and power rationing has occurred frequently. To solve this problem, SCU provided a customized 40ft container energy storage solution for a local 2MW solar farm.
The system uses SCU’s independently developed lithium battery energy storage technology and is equipped with an intelligent energy management system (EMS), which can achieve smooth output of photovoltaic power generation, grid connection, and participation in auxiliary power market services (reactive power compensation). After the project was put into operation, it not only effectively alleviated the problem of solar farm abandonment, but also significantly improved its economic benefits.
3. Three-year operation results: stable and reliable, with significant benefits
- Stable and reliable, excellent performance
For three years, the system has always maintained efficient and stable operation, with a system availability rate of more than 99% and a failure rate of less than 0.5%. Even under Bulgaria’s extreme climatic conditions (high temperatures in summer and low temperatures in winter), the system still performs well, fully verifying the high reliability and environmental adaptability of SCU energy storage products.
- Significant economic benefits
Through the peak-shaving and valley-filling function of the energy storage system, the solar farm discharges during peak electricity price periods and charges during low electricity price periods, maximizing the benefits of photovoltaic power generation. According to statistics, the system increases the revenue of customers by about 350,000 euros per year. In addition, by participating in the auxiliary services of the electricity market, the project has also obtained an additional source of income.
- Outstanding social benefits
The project can reduce carbon dioxide emissions by about 1,000 tons per year, which is equivalent to planting 40,000 trees. This not only contributes to Bulgaria’s energy conservation and emission reduction goals but also provides a replicable success case for the development of local renewable energy.
4. Successful experience: the perfect combination of technological innovation and localized services
- Technological innovation: high energy density and intelligent operation and maintenance
SCU 40ft container energy storage system adopts modular design, high energy density, small footprint, and easy transportation and installation. At the same time, the system is equipped with an advanced intelligent operation and maintenance platform, which can monitor the operating status in real-time and remotely diagnose faults, greatly reducing operation and maintenance costs. - Localized service: rapid response and customized solutions
SCU has established a localized service team in Bulgaria to provide customers with 7×24 hours of technical support. From project design to installation and commissioning, and then to later operation and maintenance, SCU always focuses on customer needs and provides customized solutions to ensure the smooth implementation and efficient operation of the project. - Win-win cooperation: creating value with customers
The success of the project is inseparable from the support and trust of customers. SCU works closely with customers, from preliminary research to later optimization, always aiming to enhance customer value, and jointly promoting the successful implementation of the project.
5. Looking to the future: Assisting the development of renewable energy in Bulgaria
With the acceleration of global energy transformation, the application of energy storage technology in the field of renewable energy will be more extensive. SCU will continue to deepen the Bulgarian market, expand its market share, and actively explore new application scenarios, such as wind storage integration, photovoltaic storage and charging integration, etc. At the same time, SCU will also strengthen cooperation with local governments and enterprises to jointly promote the development of renewable energy in Bulgaria and contribute to the global carbon neutrality goal.
6. Conclusion:
SCU’s first 40ft energy storage container project in Bulgaria is not only a successful practice of technological innovation but also an important milestone in SCU’s globalization strategy. In the future, SCU will continue to be guided by customer needs and driven by technological innovation to provide more efficient and reliable energy storage solutions to global customers, help energy transformation, and create a green future together.
