About Ib Vogt

Based in Berlin, Germany, ib vogt operates as a global developer of utility-scale solar photovoltaic (PV) plants and battery energy storage systems (BESS). Founded in 2002 by chemical engineer Dagmar Vogt, the company initially focused on engineering and project management for PV factory construction. Vogt's background in plant construction since 1991 and her entry into the solar industry in 1998 laid the foundation for the firm's establishment. Anton Milner, former CEO of Q-Cells, joined in 2011 and became Managing Director in 2012, eventually taking the CEO position, which he held for 15 years before Andreas Schell was appointed in June 2025.

The firm's business model is vertically integrated, covering the entire project lifecycle. This includes project development, design, engineering, financing, Engineering, Procurement, and Construction (EPC), as well as ongoing Operations and Maintenance (O&M) and asset management. In 2009, the company shifted its strategic focus from factory engineering to the development of large-scale turnkey PV plants, initially in Germany and the UK. A significant part of its strategy is its evolution into an Independent Power Producer (IPP), which involves owning and operating a portfolio of renewable energy assets to generate recurring revenues. This IPP model, enhanced by an asset rotation strategy, allows the company to capture value throughout the project's life and offers opportunities for capital deployment.

ib vogt serves a diverse client base that includes utility-scale customers, independent power producers, and industrial clients. Revenue is generated through multiple streams, including the sale of fully developed and constructed solar projects, long-term O&M contracts, and returns from its IPP portfolio through power purchase agreements (PPAs) with partners like Google. The company has a substantial global presence, with offices across Europe, the Americas, Africa, and Asia Pacific, operating in over 35 countries. It has secured significant financing from institutions like Santander CIB, Commerzbank, BAE Systems Pension Funds, and EIG Global Energy Partners to fuel its expansion. In early 2025, Qualitas Energy acquired the company.

The company's core offering is the delivery of high-performance turnkey solar power plants and, increasingly, co-located or stand-alone battery storage solutions. Its project pipeline is substantial, with over 4.7 GW of PV power plants built or in construction and a development pipeline exceeding 55 GWp, including a 12 GW BESS pipeline. The firm manages projects from site identification and permitting to grid connection and long-term operation, aiming to de-risk projects through meticulous planning and execution. This comprehensive service model allows clients to minimize risks while maximizing the operational efficiency and financial returns of their solar investments.
