HOME / City Scale Integration Of Distributed Energy Storage - GPE Utility Storage
The new 30 MW energy storage plant – with a storage capacity of 30 MWh – is located in Yllikkälä, close to the city of Lappeenranta in Southeast Finland.
Swedish flexible assets developer and optimizer Ingrid Capacity has joined hands with SEB Nordic Energy's portfolio company Locus Energy to develop what is claimed to be Finland's largest and one of the Nordics' largest battery energy storage systems (BESS). The 70 MW/140 MWh BESS project will be located in Nivala, northern Finland.
After the start of commercial operations in 2026, the project will contribute an important balancing function to the Finnish grid, supporting the Finnish renewable energy expansion. The groundbreaking ceremony took place in the afternoon on Monday the 26th of May on the site near Nivala where the battery energy storage system will be built.
It is a very good complement to our renewable project developments in Finland,” says Prot. Antero Reilander comments that while there have been other battery storage projects in Finland, this one is the biggest – by far. Despite the size of the undertaking, the project has proceeded very smoothly indeed.
Currently, utility-scale energy storage technologies that have been commissioned in Finland are limited to BESS (lithium-ion batteries) and TES, mainly TTES and Cavern Thermal Energy Storages (CTES) connected to DH systems.
Reserve markets are currently driving the demand for energy storage systems. Legislative changes have improved prospects for some energy storages. Mainly battery storage and thermal energy storages have been deployed so far. The share of renewable energy sources is growing rapidly in Finland.
“Yllikkälä is a key project for our company, being the largest of its kind for us in Europe. It is a very good complement to our renewable project developments in Finland,” says Prot. Antero Reilander comments that while there have been other battery storage projects in Finland, this one is the biggest – by far.

Hybrid energy storage systems (HESS), which combine multiple energy storage devices (ESDs), present a promising solution by leveraging the complementary strengths of each technology involved.
4.1.4. Energy Storage Systems Expansion from a Technology Point of View Fortunately, nowadays, the growth of energy storage systems is based on renewable energy; the development of both sustainable energy and low-carbon electricity systems has resulted in promising solutions for energy system integration .
Using PEST analysis, we demonstrated that governments, national officials, and people have key roles in expanding energy storage systems for renewable power integration. Figure 1 shows the framework of the methodology of this paper. It implies that a collaboration between officials and people is necessary to expand energy storage.
Introduction Energy Storage System (ESS) integration into grid modernization (GM) is challenging; it is crucial to creating a sustainable energy future . The intermittent and variable nature of renewable energy sources like wind and solar is a major problem.
Modern energy infrastructure relies on grid-connected energy storage systems (ESS) for grid stability, renewable energy integration, and backup power. Understanding these systems' feasibility and adoption requires economic analysis. Capital costs, O&M costs, lifespan, and efficiency are used to compare ESS technologies.
It is also essential to develop new energy storage technologies that are environmentally friendly for citizens . Innovative solutions play an essential role in supporting the transition to a new energy-saving system by expanding energy storage systems.
Implementing energy storage systems, particularly those that use lithium-ion batteries, has demonstrated significant benefits in enhancing grid stability, easing the integration of renewable energy sources, and guaranteeing reliable backup power.
DG often includes electricity from renewable energy systems such as solar photovoltaics (PV) and small wind turbines, as well as battery energy storage systems that enable delayed electricity use.
Generally speaking, the main benefits of installing energy storage system (ESS) and distributed generation (DG) in distribution systems are : (i) to reduce carbon emissions; (ii) to balance the unpredictable fluctuations of renewable energy and demand; (iii) to reduce the energy exchanges at substations and to reduce the total power losses.
Distributed generation is the energy generated near the point of use. The ongoing energy transition is manifested by decarbonization above all. Renewable energy is at the heart of global decarbonization efforts. Distributed energy systems are complimenting the renewable drive.
The energy storage system is connected to the distribution network, and the two storage systems assume the responsibility of supplying power to some nodes. The introduction of energy storage in the distributed PV distribution network reduces the dependence on thermal generators and improves the rate of elimination and economy.
Distributed energy resources (DER), encompassing distributed generation (DG), energy storage systems (ESS), and controllable loads, is an effective technique for enhancing power distribution system reliability and power quality .
DES can employ a wide range of energy resources and technologies and can be grid-connected or off-grid. Accordingly, distributed generation systems are making rapid advancements on the fronts of technology and policy landscapes besides experiencing significant growth in installed capacity.
Extensive research has been conducted on the optimized placement of distributed energy storage systems to improve the reliability and resilience of distribution power systems. However, several limitations and areas for improvement remain, as highlighted in prior studies.
Grid-scale energy storage is a longstanding component of power networks and represents any form of technology connected to the power grid capable of storing energy and resupplying it back to the grid at a favourable time.
[PDF Version]When asked to define grid-scale energy storage, it's important to start by explaining what “grid-scale” means. Grid-scale generally indicates the size and capacity of energy storage and generation facilities, as well as how the battery is used.
Another factor is where the batteries are stored, as batteries kept in higher or very low temperatures can experience a shorter lifespan. Energy systems that use grid-scale battery storage are more reliable, efficient, and environmentally friendly. A top benefit is the ability to stabilize the grid during fluctuations from renewable sources.
The current market for grid-scale battery storage in the United States and globally is dominated by lithium-ion chemistries (Figure 1).
There are several different types of grid-scale batteries, and each has their own applications and specifications, including: Lithium-ion battery energy storage systems are the most common electrochemical battery and can store large amounts of energy. Examples of products on the market include the Tesla Megapack and Fluence Gridstack.
The lifespan of a grid-scale battery depends on its chemistry, how long the battery has been used, and how often it's charged and discharged. Applications of lithium-ion batteries in grid-scale energy storage systems last about 10–15 years. Lead-acid is between 5–10 years.
Grid-scale is different in terms of battery size and use cases than residential scale or commercial and industrial sale. Here is a breakdown of the differences between the three main levels of energy storage systems:
Let's cut through the noise - photovoltaic storage cabinets are rewriting energy economics faster than a Tesla hits 0-60. As of February 2025, prices now dance between ¥9,000 for residential setups and ¥266,000+ for industrial beasts.
