Energy Storage Systems (ESS): An Innovative Solution for Modern Enterprises

Your Energy — Your Control! Imagine an enterprise that is not affected by fluctuations in electricity prices and always has access to affordable energy at any time. This is precisely what energy storage systems (ESS) from Green Line Energy provide — an innovative solution that fundamentally transforms the approach to energy consumption.

Who Are ESS Solutions For?
Energy Storage Systems (ESS) are advanced technological complexes that store electricity and allow its use during peak hours or outages.
In 2023, demand for energy storage systems in Ukraine increased by 14%, according to “Market Operator.” This statistic highlights that ESS is an ideal solution for enterprises aiming to optimize electricity costs and ensure uninterrupted operations.
These enterprises include:

  • Manufacturing Companies (metallurgy, food industry, chemical industry) operating 24/7 with high energy demands.
  • Logistics and Warehousing Centers requiring stable operation of refrigeration units and other equipment.
  • Medical Institutions and Pharmaceutical Companies where uninterrupted equipment operation is critical.
  • IT Companies and Data Centers needing constant access to electricity for data storage and processing.
  • Agricultural Enterprises, particularly those involved in storing products at low temperatures.
  • Solar Power Plants and Green Energy Businesses aiming to maximize the efficiency of their energy generation.

Infrastructure projects, condominiums, residential complexes, cottage communities, retail and office buildings.

Advantages of using ESS for business and enhancing enterprise competitiveness

Savings on electricity costs of 20-30% or more

Electricity Arbitrage. Electricity prices in Ukraine fluctuate throughout the day. This allows enterprises to charge ESS when electricity prices are at their lowest and use the stored energy when prices are higher. Over a typical 24-hour period, two cycles of energy storage and consumption can be identified. The first cycle begins at night when electricity prices are at their lowest. Charging generally takes place until around 5 a.m. Starting at 6 a.m., electricity prices rise sharply. Therefore, it is efficient to use the stored energy between 6 a.m. and 10 a.m. From approximately 10 a.m. to 3 p.m., electricity prices are relatively low again, allowing a second cycle of energy storage for use during the evening hours. Around 4 p.m., prices begin to rise steeply, peaking at 7 p.m. During this time and until the end of the day, it is advisable to use the stored energy. According to the State Statistics Service of Ukraine and energy market experts, enterprises that use ESS for electricity arbitrage can reduce their electricity costs by 20-30%.

Cost optimization and profitability improvement

By using ESS, enterprises reduce energy consumption from the grid during peak hours, leading to overall cost optimization.

Autonomy and protection from power outages

ESS provides uninterrupted power supply for critical business processes during power outages. This is crucial for any business, production facility, or activity where each disruption can result in significant losses. According to the analytical portal Energy Storage News, enterprises that have implemented ESS have reduced losses caused by power supply interruptions by 50%.

Accelerated payback by approximately one year through integration with solar power plants (SPPs).

The combination of ESS with a solar power plant allows storing generated energy for use during evening and nighttime hours. This not only enhances the efficiency of the solar power plant but also reduces dependence on external energy sources.

Environmental image

Using ESS helps reduce the consumption of traditional energy resources and lower CO₂ emissions, contributing to an improved environmental image for the enterprise. This is crucial for companies striving to meet international environmental standards and attract partners focused on environmental responsibility.

Rapid return on investment, 15-20% faster

Due to savings on electricity costs and reduced downtime risks, the payback period for energy storage systems in 2024 has decreased to 4-6 years, depending on the type of enterprise and scale of consumption. Companies that have invested in ESS typically achieve payback 15-20% faster, thanks to price fluctuations and improved energy management efficiency.

ESS technical information

The main components of ESS:

  • Battery Modules — the heart of the system that stores electricity (Lithium-based: (LiCo), (LiMn), (Li-Pol, Li-polymer, Li-Po), (LiFePO4), (LTO), (Li-NMC, NMC)).
  • Energy Management System (EMS) — software for monitoring and optimizing system performance.
  • Voltage Converters (Inverters) — ensure the transfer of stored energy to the grid or end user.
  • Cooling System — maintains the optimal operating temperature of the batteries, extending their lifespan.

Types of ESS:

  • Stationary — used for manufacturing and logistics enterprises.
  • Mobile — compact solutions for temporary facilities.
  • Integrated with RES (Renewable Energy Sources) — ensure maximum efficiency of solar and wind power plants.

Power and Capacity:

Systems can range in power from several kilowatts (kW) to several megawatts (MW) and in capacity from kilowatt-hours (kWh) for small businesses and private households to megawatt-hours (MWh) for large industrial facilities.

Case

Topic: Calculating Savings and Payback Period for an ESS System (Power: 800 kW, Capacity: 1600 kWh)

Case Description:

The use of an Energy Storage System (ESS) with a power of 800 kW and a capacity of 1600 kWh significantly reduces electricity costs by charging batteries at night and during the day when prices are at their lowest and utilizing stored energy during peak hours in the morning and evening. In this case, we will analyze daily savings and the payback period of the project based on current electricity prices in Ukraine in 2024.

Calculations:

1. Night Charging (Cost):

Charging battery capacity: 1280 kWh (80% of total capacity).

Night electricity price: 2.5 UAH/kWh.

Charging cost: 1280 kWh × 2.5 UAH = 3200 UAH.

2. Morning Peak (Savings):

Morning electricity price: 7 UAH/kWh.

Savings per kWh: 7 – 2.5 = 4.5 UAH.

Total savings for the morning cycle: 4.5 × 1280 = 5760 UAH.

3. Evening Peak (Savings):

Evening electricity price: 9 UAH/kWh.

Cost of stored energy (daytime minimum): 1280 kWh × 2 UAH = 2560 UAH.

Savings for the evening cycle: (1280 kWh × 9 UAH) – 2560 UAH = 8960 UAH.

4. Daily Savings:

Morning cycle + Evening cycle: 5760 UAH + 8960 UAH = 14,720 UAH.

5. Annual Savings:

14,720 UAH × 365 days = 5.3 million UAH.

6. Payback Period:

Project cost (turnkey): 27.4 million UAH.

Included in the Project Cost:

  • Equipment cost.
  • Integration into the existing network.
  • Design, installation, configuration, and commissioning.
  • Daily Energy Savings: 14,720 UAH.

Payback Period:

27.4 million UAH ÷ 5.3 million UAH ≈ 5.2 years.

Calculations Excluding VAT

Conclusion:

Installing this ESS system enables daily savings of 14,720 UAH. At current tariffs, the system will pay for itself in 5.2 years, which is an attractive timeframe for investment. These calculations are based on current prices and may vary depending on market conditions.
