A municipal services company in Krosno is seeking to design and build new battery energy storage facilities at two of its sites, aiming to improve electricity balancing for its own operations and for the Krosno Energy Cluster. The move places local storage at the heart of how public bodies manage power flows, and it reflects a broader shift across municipalities and utilities towards integrating energy storage into everyday infrastructure.
Published on 15th January 2026, the contract notice from Miejskie Przedsiębiorstwo Gospodarki Komunalnej – Krośnieński Holding Komunalny Spółka z ograniczoną odpowiedzialnością sets out a compact but significant brief. Under the Construction of Energy Storage Facilities procurement, the company plans to:
The combination of documentation and construction points to a design-and-build approach. Rather than buying ready-made systems, the municipal company wants a contractor to carry the project from planning through to delivery, including the technical and permitting work needed to integrate new storage into its operations.
The explicit reference to the Krosno Energy Cluster is notable. Many recent public-sector energy tenders focus on individual buildings or portfolios, but this notice ties storage to a wider local energy structure. The facilities are expected to help balance electricity not only for the municipal services company but also for the cluster as a whole, signalling coordination across different energy users.
Electricity balancing is about aligning production and consumption over time. Storage allows organisations to absorb surplus power in one moment and release it in another. The Krosno project positions battery storage as a flexible tool for that task within a defined local area.
Several other recent tenders show how public buyers are using similar systems at different points in the power system. On 30th December 2025, PGE Dystrybucja S.A. published a contract notice for the Construction of Energy Storage Facilities in Warta and Jeziorsko. That project couples two new storage facilities with a new automated power distribution station and the modernisation of an existing station, illustrating how storage is being combined with grid automation and network upgrades.
Further upstream, PGE Inwest 22 Sp. z o.o. set out plans on 7th October 2025 for an Electric Energy Storage Construction project in Gryfino. That notice calls for the design and implementation of a complete storage facility, including all required documentation, permits, installations and services. Like the Krosno tender, it bundles technical design and construction into a single contract, pointing to a preference among large buyers for turnkey delivery of complex storage assets.
At the other end of the scale, municipalities are using storage to balance power flows at individual properties. In Wojnicz, a contract notice from 3rd September 2025 covers the Energy Storage Systems Installation for 38 residential properties. The systems are intended to store electricity from existing photovoltaic installations, turning household solar into a more controllable resource.
Projects in Ciechanów and Suski County take a similar approach at greater scale. The 14th November 2025 tender from Gmina Miejska Ciechanów for Energy Storage Systems for Ciechanów covers designing, delivering, installing and commissioning storage systems for eight public utility buildings and 162 private buildings, funded by European Funds to enhance renewable energy sources and optimise electricity consumption. On 26th November 2025, Powiat Suski launched an Energy Storage Installation Project to design and execute storage for photovoltaic systems in 100 residential houses and three public buildings, with the explicit goal of enhancing renewable energy use and environmental quality.
In this context, Krosno’s plan sits midway between household schemes and large utility assets. By linking storage to an energy cluster, the municipal company is treating flexibility as a shared local resource rather than a feature of single buildings alone.
Across recent public-sector tenders, energy storage is often paired with new or existing renewable generation. This is especially evident in projects centred on photovoltaic installations and public services.
On 22nd August 2025, Miasto Ostrołęka published a notice for a Photovoltaic Installation with Energy Storage to charge electric buses at the Municipal Communication Company base in Ostrołęka. The scope includes design documentation, delivery, installation and commissioning of both the photovoltaic system and a battery energy storage system, supported by an energy management system to optimise electricity consumption. Here, storage directly underpins low-emission transport infrastructure.
In the water sector, Górnośląskie Przedsiębiorstwo Wodociągów Spółka Akcyjna plans a photovoltaic power plant with storage at a site in Pyskowice. Its 25th August 2025 notice for Renewable Energy Installation Construction covers designing, constructing and commissioning a photovoltaic plant, alongside an energy storage system and grid connection.
Municipalities are also equipping schools, cultural sites and administrative buildings with solar panels and storage. The 2nd September 2025 notice from Gmina Tarnowskie Góry for Renewable Energy Installations in Tarnowskie Góry involves 26 photovoltaic systems with energy storage across schools, kindergartens and cultural centres. On 2nd January 2026, Gmina Zawiercie followed a similar pattern with a tender for Photovoltaic Installations in Zawiercie, specifying two photovoltaic systems and six systems with energy storage for public utility buildings.
The pattern continues into January 2026. Gmina Daleszyce’s notice of 5th January 2026 for Photovoltaic Installations in Daleszyce aims to expand municipal infrastructure through photovoltaic systems with energy storage at various public facilities. On 21st January 2026, Miasto Katowice sought Photovoltaic Installation Documentation for two systems with energy storage, explicitly linking the investment to reducing emissions and improving air quality.
Gmina Lipowa’s notice, also dated 21st January 2026, for Renewable Energy Installations in Lipowa again combines photovoltaic systems, energy storage and an energy management system for public utility buildings. Meanwhile, Gmina Ostrów Mazowiecka’s 2nd January 2026 tender for Energy Storage Systems Installation covers storage with hybrid inverters for 124 residential units and nine public utility buildings.
Some buyers are going further, combining battery storage with other vectors. On 23rd January 2026, SPÓŁDZIELNIA NYSKA ELEKTROWNIA SPOŁECZNA released a notice for Photovoltaic Power Plant Construction in Nysa. The project combines a photovoltaic power plant of up to 10 MW with a battery energy storage system and green hydrogen storage, alongside the necessary technical infrastructure and documentation.
Seen against this backdrop, the Krosno tender reinforces a clear message: for public bodies, new renewable capacity and new storage capacity now tend to move together.
Energy storage investments are emerging alongside more traditional electricity supply contracts, suggesting that public entities are trying to manage both sides of their energy position: how they buy power and how they use or store it.
On 21st August 2025, Krakowski Holding Komunalny Spółka Akcyjna w Krakowie issued a contract notice for Electricity Supply for Krakow Group. The service covers purchasing and delivering energy, settling produced energy and repurchasing surplus energy for participants in Krakow and the Małopolskie Voivodeship over a two-year period. The structure recognises that some participants are both consumers and producers, with surplus energy to be repurchased.
Similarly, the 3rd November 2025 notice from Miejskie Przedsiębiorstwo Gospodarki Komunalnej Spółka z ograniczona odpowiedzialnością for Electricity Supply for MPGK combines the supply of electricity with the purchase of surplus energy from renewable installations. In Rzeszów, the Podkarpacki Zespół Placówek Wojewódzkich published a 10th October 2025 tender for Electricity Supply for Facilities, covering both supply and distribution services for multiple locations.
These contracts show public buyers structuring their energy purchases around dynamic flows of consumption, on-site production and surplus. When viewed alongside the wave of storage and renewable tenders, they reinforce the picture of local authorities and public utilities acting as active participants in the power system, rather than passive customers.
The Krosno battery storage project is compact in description but potentially influential in how local energy is managed. If delivered as set out in the notice, the two new facilities will give the municipal services company and the Krosno Energy Cluster a shared asset for balancing electricity across multiple sites.
Key points to watch will be how far the contracted solution integrates with existing and future renewable generation in the cluster, how responsibilities are split between the municipal company and cluster participants, and whether further tenders follow for energy management systems or additional storage. The growing number of public-sector projects pairing renewables, storage and structured energy procurement suggests that Krosno’s approach is unlikely to be the last of its kind.
