Technical EPC tendering for

\n
\n

Photovoltaics (PV)<\/h3><\/div><\/div><\/div>\n\n

For photovoltaic projects, we prepare structured technical tender documents covering all essential aspects of design, component selection, DC\/AC design, yield assumptions, and construction quality. We define clear minimum technical requirements, check incoming EPC bids for plausibility and comparability, and evaluate, among other things, plant design, string concepts, cable lengths, yield simulations, and quality approaches. The goal is a reliable decision-making basis that considers both economic efficiency and long-term operational reliability.<\/p>\n<\/div><\/div>\n<\/div>\n\n

\n

Battery Storage (BESS)<\/h3><\/div><\/div><\/div>\n\n

For battery storage projects, the focus is on the clear technical definition of system architecture, performance, capacity, operating strategy, and grid integration. We structure the tender so that storage technology, inverter concept, control and protection technology, safety requirements, as well as warranty and degradation assumptions can be evaluated transparently and comparably. We analyze the bids particularly with regard to technical design, interfaces to the grid connection and the superordinate plant control, and the feasibility of the intended operating mode. <\/p>\n<\/div><\/div>\n<\/div>\n\n

\n

Substations (SS)<\/h3><\/div><\/div><\/div>\n\n

For substations, we support the preparation of technical tenders that focus on AC-side system integration. This includes switchgear concepts, protection and control technology, transformer design, measurement concepts, and compliance with grid operator-specific and normative requirements. We check bids for technical completeness, interface clarity, and feasibility, thereby creating a sound basis for a secure, compliant, and timely connection of PV and BESS projects to the grid. <\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

Tendering with a focus on implementation and certification<\/span><\/h2>\n<\/div><\/div>\n\n

greentech consistently thinks beyond the bidding phase in technical EPC tendering. Already during the preparation of the tender documents, we consider requirements for grid connection, plant certification, acceptance, and trial operation. This ensures that the proposed solutions are not only technically comparable but also realistically implementable and certifiable \u2013 and avoids later discrepancies, additional claims, or costly adjustments during the realization phase.<\/p>\n<\/div><\/div>\n<\/div>\n\n
