Commercial management: Maximum profitability and joint commitment to the energy transition.

Who advises you on optimisation and savings potential in current and future operations and also performs cost and performance benchmarking in the O&M area? For almost 15 years, greentech has specialised as an independent service provider in the commercial management of photovoltaic plants and transfers this knowledge to the field of battery storage systems.
We manage portfolios of utilities, renowned investment funds and also individual investors. Whether rooftop, large ground-mounted system or large scale battery storage systems, whether young or old – we are there for you personally and with advice at every stage of the system’s life. We are also guided by our conviction that plants that fully exploit their potential and demonstrate good profitability not only satisfy operators and investors – they also increase the attractiveness and reputation of renewables as a whole, thus ensuring greater PV and BESS additions in the long term.

REDUCE COSTS
Benchmarking by an independent operating guide
Professional operation of a solar power plant or a battery energy storage system is about technical and commercial expertise. It is obvious, that a reduction of the OPEX will pay off financially. However, in many cases costs, scope and contracts are a black box for the operator/investor.
In order to provide you as an investor with maximum transparency regarding operating costs and to identify cost reduction potential during the operating phase, we offer you independent cost benchmarking. In the first step, we look at your actual costs and compare them with the greentech benchmark, which has been determined through many years of experience. In a second step, your specific and individual scope of services for technical and commercial management is reviewed and appropriate target prices are calculated. This forms the basis for renegotiations and adjustments to the scope of services as a final step. The greentech experts accompany the entire process until you have achieved your ideal price-performance ratio for PV and BESS services.
