30 MW / 60 MWh BESS — Austria (Styria)

This is a separate, earlier-stage opportunity from NEBO (nebo.energy), distinct from NEBO's 93.5 MW / 7-site ready-to-sign BESS portfolio listed separately on Wattilla. Beyond that named portfolio, NEBO controls a further pipeline of approximately 900 MW of BESS projects across Poland, at an earlier stage of development. No site plots, GPZ substations, distances or confirmed grid connection dates have been disclosed for this part of the pipeline. This opportunity is intended for buyers or developers looking to acquire an active BESS development pipeline in the Polish market ahead of technical conditions and grid connection applications, rather than a specific, itemised set of sites. Given the early stage and lack of site-level disclosure, interested buyers should contact NEBO directly for a fuller briefing, likely under NDA.

NEBO (nebo.energy) is a Warsaw-based renewable energy developer with over 7 years of market experience and more than 2.5 GW of total capacity developed across photovoltaic, wind and energy storage projects. In 2023 Nebo sold a 100 MW / 16-project solar PV portfolio to hep Global (Germany), continuing its development to Ready-to-Build stage under a development service agreement — a track record directly relevant to the type of transaction offered here. This listing offers a portfolio of 7 stand-alone battery energy storage (BESS) development sites across Poland, presented together as a single opportunity. Combined installed power of 93.5 MW with 50 MW of grid connection capacity already secured for charging and discharging. Land is controlled at every site and grid connection conditions have been granted at all 7; at 3 of the 7 (Śmigiel, Bydgoszcz, Środa Wielkopolska), Nebo has already progressed to a signed grid connection agreement — the stronger bankability milestone. Storage duration is configurable at each site, either 2h or 4h. Every site connects into a 110/15kV GPZ substation operated by Enea or Energa, with the project itself connecting at the 15kV side. Target commercial operation date is Q3–Q4 2027, with a maximum deadline of Q4 2028 under the Grid Connection Agreement. Site-by-site overview: - Śmigiel — plot 91/4, GPZ Enea Śmigiel, 0.5 ha, ~110 m to connection point. 8.1 MW installed, 3 MW connection (Phase I), up to 20 MW (Phase II). Grid connection granted, grid connection agreement signed. - Tuczki — plot 150, GPZ Energa Tuczki, 0.98 ha, <0.5 km to connection point. 2 MW installed, 2 MW connection. Grid connection granted. - Bydgoszcz — plot 12/13, GPZ Enea Bydgoszcz, 1 ha, 400 m to connection point. 8.1 MW installed, 6 MW connection. Grid connection granted, grid connection agreement signed. - Chwalecice (Kłodawa) — plot 228, GPZ Enea Gorzów Słowiański, 0.5 ha, <5 km to connection point (an alternative <200 m location is in progress). 8.1 MW installed, 6 MW connection. Grid connection granted. - Mosina — plot 2776, GPZ Enea Mosina, 0.6 ha, ~0.85 km to connection point. 17.2 MW installed, 13 MW connection. Grid connection granted. Building Permit already obtained. - Środa Wielkopolska — plot 4038/2, GPZ Enea Środa Wielkopolska, 0.6 ha, ~1.9 km to connection point. 25 MW installed, 10 MW connection (Phase I), up to 30 MW (Phase II). Grid connection granted, grid connection agreement signed. - Śrem — plot 2467/16, GPZ Enea Śrem HCP, 1.37 ha, ~0.5 km to connection point. 25 MW installed, 10 MW connection (Phase I), up to 50 MW (Phase II). Grid connection granted. Beyond this stand-alone pipeline, Nebo also controls a 100 MW hybrid PV+BESS project with grid connection already granted, plus a further c.900 MW of BESS projects at an earlier stage of development — available for discussion alongside this portfolio. Available as a full portfolio or, potentially, split by site, with a minimum of 4 sites acquired. Asking price on request. Poland's grid connection framework changed in April 2026 (amended Energy Act) — connection conditions carry a limited validity window, which adds urgency for buyers evaluating this pipeline. Contact Nebo for the full data room: technical connection conditions, signed agreements where applicable, and site maps.

LSG Group GmbH (LSG Building Solutions) is a privately owned, multi-domestic engineering and construction group headquartered in Vienna, Austria, ~400 employees, permanent operations in Austria, Croatia, Romania, Bulgaria, Serbia, Macedonia and Moldova. Full life-cycle EPC partner: consulting, project development, design, construction, O&M. Track record — BESS & hybrid power plant projects: - Izvoarele 2 HPP, Romania, 2026 — 160 MWh BESS (LFP) + 50 MW PV — EPC. >€20M investment, grid ancillary services (FCR/aFRR/mFRR) for Romania's TSO. - BESS Senyo, Hungary, 2024–2025 — 115 MWh BESS (40→115 MWh expansion) + 20 MWp PV — EPC. BESS containers by HITHIUM. - Glyptodon / CEM Carani HPP, Romania, 2024–2025 — 68.8 MWh BESS + 56 MWp PV — EPC. First hybrid power plant of its kind in Romania, currently in aFRR qualification. Beyond BESS, LSG has delivered 60+ solar PV projects since 2011 across Austria, Hungary, Bulgaria, Romania and beyond, totaling over 2,100 GWh of installed renewable generation. Vendor-neutral — worked with multiple battery suppliers (Trina Storage, HITHIUM). Open to EPC, engineering and O&M mandates on BESS and hybrid projects across Europe.

Wattrix (BEG Wattrix e.Gen.) is a registered citizen energy community (Burgerenergiegemeinschaft) supplying renewable electricity across Austria. We aggregate distributed solar generation today, with wind and hydro assets joining the community in 2026, and dynamically redistribute electricity among members every 15 minutes at flat, transparent rates (9.5 ct/kWh for consumption, 8 ct/kWh for feed-in). As we scale toward maximum self-sufficiency for our members by 2027, battery storage is a natural next step: it lets us shift surplus renewable generation to periods of peak community demand, smooth the mismatch between intermittent PV/wind/hydro output and consumption, and further reduce our members' reliance on the wholesale market. We're open to hearing from BESS project developers, asset owners and hybrid (generation + storage) project developers in Austria interested in exploring integration or off-take partnerships with our community, as well as from BESS system suppliers who want to understand community-scale storage use cases. Get in touch to discuss. Vendor-neutral - not affiliated with any equipment manufacturer or EPC contractor.
