public references from 2025 and 2026 include Onde, Electrum, Nomad Electric, P&Q and Esix (Polish companies), Goldbeck Solar Polska and LG Energy Solution Wroc\u0142aw (subsidiaries of foreign groups), and for grid connections Elektrotim, Elfeko, Energoaparatura, Elmont Grupa and Enprom.\"}}, {\"@type\": \"Question\", \"name\": \"Is this a complete list of EPC contractors in Poland?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No. The companies named here are examples with verifiable public references as of October 2026. Many more contractors build solar, BESS and grid connections in Poland, and a target list for a specific product or project usually includes companies not named here.\"}}, {\"@type\": \"Question\", \"name\": \"Do Polish EPCs work with foreign equipment suppliers?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes. Large Polish BESS projects use imported battery systems: BYD supplied Turo\u015b\u0144 Ko\u015bcielna, built by P&Q, and LG Energy Solution supplies \u017barnowiec from its plant near Wroc\u0142aw. In BoP contracts the investor often buys the main equipment directly, as in R.Power's Dzi\u0119gielewo contract with Onde, which excludes the battery system.\"}}, {\"@type\": \"Question\", \"name\": \"How do I get on an EPC's approved supplier list?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"In our experience, contractors and investors ask for technical documentation, certificates, references from comparable projects and proof that the equipment meets the operator's requirements, with documents in Polish. Because the investor often buys the main equipment, approach the investor's procurement team and the EPC's procurement team in parallel.\"}}, {\"@type\": \"Question\", \"name\": \"Can one EPC build both the plant and the grid connection?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Some do, for example Goldbeck Solar Polska at Postomino or Onde at Dzi\u0119gielewo, where the scope includes the GPO and the high-voltage line. Others subcontract this part. Check it in the contract scope and with past clients.\"}}, {\"@type\": \"Question\", \"name\": \"Who owns the grid that solar and BESS projects connect to in Poland?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"PSE owns the transmission network at 220 and 400 kV. Distribution is run by PGE Dystrybucja, Energa-Operator, Enea Operator, Tauron Dystrybucja and Stoen Operator. They issue connection conditions and accept the connection works but do not build private plants.\"}}, {\"@type\": \"Question\", \"name\": \"Who is building the largest battery storage projects in Poland?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"As of October 2026: P&Q built the 200 MW \/ 800 MWh Turo\u015b\u0144 Ko\u015bcielna BESS, LG Energy Solution Wroc\u0142aw is building

class=\"tnb-rule tnb-tx-p tnb-grow\" aria-hidden=\"true\" style=\"background:#64476c\"><\/span>\n<p class=\"tnb-lead\">Utility-scale solar and BESS projects in Poland are built by three different groups: contractors that build the plant itself (EPC or balance of plant), contractors that build the grid connection (the GPO substation, 110 kV lines, bays in the operator&#8217;s substation), and the network owners, PSE and the distribution system operators, who set the connection conditions and accept the work. Most large Polish EPCs are Polish companies; a few are subsidiaries of foreign groups. Many contractors say they do everything, so the real scope has to be checked against their references.<\/p>\n<p class=\"tnb-meta\"><span>By <b>Dima V.

They are often mixed up, and they buy, specify and approve different things.<\/p>\n<p class=\"tnb-def\">An EPC contractor (engineering, procurement and construction) designs a power plant, buys its equipment and builds it under a single contract. A grid-connection contractor builds the link between the plant and the network: in Poland usually the GPO substation (g\u0142\u00f3wny punkt odbioru) and a 110 kV line to the operator&#8217;s substation.<\/p>\n<div class=\"tnb-tbl\">\n<table>\n<thead><tr><th scope=\"col\">Role<\/th><th scope=\"col\">What they do<\/th><th scope=\"col\">Examples<\/th><\/tr><\/thead>\n<tbody>\n<tr><td>Network owners<\/td><td>Issue connection conditions, own and maintain their substations and lines, accept the connection works<\/td><td>PSE (transmission, 220 and 400 kV); PGE Dystrybucja, Energa-Operator, Enea Operator, Tauron Dystrybucja, Stoen Operator (distribution)<\/td><\/tr>\n<tr><td>Plant builders<\/td><td>Build the solar farm or battery site: civil works, structures, MV infrastructure, integration, often the GPO<\/td><td>Onde, Electrum, Nomad Electric, Goldbeck Solar Polska, P&amp;Q<\/td><\/tr>\n<tr><td>Connection contractors<\/td><td>Build the GPO substation, 110 kV cable or overhead lines and bays in the operator&#8217;s substation<\/td><td>Elektrotim, Elfeko, Elmont Grupa, Energoaparatura, Enprom<\/td><\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>Network owners are not contractors. They do not build your plant, but their standards and acceptance procedure decide whether your plant is energised on time. Work on their own networks is procured separately: PSE, for example, contracted SPIE Energy Poland and Elfeko to extend the Gda\u0144sk B\u0142onia 400\/110 kV substation for over PLN 402 million (<a href=\"https:\/\/inwestycje.pl\/biznes\/pse-zlecily-rozbudowe-stacji-elektroenergetycznej-gdansk-blonia-za-ponad-402-mln-zl\/\" target=\"_blank\" rel=\"noopener\">Inwestycje.pl<\/a>), and Budimex to modernise the Pi\u0142a Krzewina 110\/220\/400 kV substation (<a href=\"https:\/\/www.gramwzielone.pl\/?p=20199976\" target=\"_blank\" rel=\"noopener\">Gramwzielone<\/a>). These 400 kV specialists matter for a typical solar or BESS project only when it connects directly to the transmission network.<\/p>\n<p>The buyers sit on the other side: utilities such as PGE and Enea, and independent producers and developers such as R.Power, Greenvolt, Polenergia, EDF and Green Capital.

Because the investor often buys the main equipment, approach the investor&#8217;s procurement team and the EPC&#8217;s procurement team in parallel.<\/p><\/div>\n<div><h3 class=\"tnb-h\">Can one EPC build both the plant and the grid connection?<\/h3><p>Some do, for example Goldbeck Solar Polska at Postomino or Onde at Dzi\u0119gielewo, where the scope includes the GPO and the high-voltage line.
