35 MW / 140 MWh BESS — Hungary

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.
