Die aktuelle Situation bei der Entwicklung von BESS-Projekten, insbesondere im Hinblick auf die Erreichung der Rentabilität, wird zunehmend durch volatile Märkte, zunehmende Netzbeschränkungen und sich rasch ändernde gesetzliche Rahmenbedingungen erschwert. Bestehende Lösungen sind oft veraltet und unzureichend (Excel-basierte Arbeitsabläufe), unangemessen und voreingenommen (Händler) oder teuer und langsam (Berater). Re-Twin begegnet diesem Problem durch fundierte, projektspezifische Analysen und Prognosen, die alle technischen Spezifikationen, finanziellen Eventualitäten und auferlegten Einschränkungen berücksichtigen. Die Ergebnisse werden in übersichtlichen, umsetzbaren Gegenüberstellungen dargestellt und ermöglichen so eine schnelle Entscheidungsfindung auf der Grundlage einer transparenten und fundierten Methodik.
