Digital Procurement Meets Green Innovation
HEJA Grüne Speicher and Digital Purchase Order (DPO) provide an efficient solution for procurement and budget management in large-scale renewable energy projects.
HEJA develops and operates tailored energy storage systems for industrial, agricultural, and residential use. With a modular portfolio ranging from 10 kWh to 10 MWh (LTO and supercaps), the company covers all stages—from feasibility studies and subsidy analysis to complex hydrogen solutions. The focus is always on balancing sustainability and return on investment.
Delivering such projects requires strict budget control. This is where DPO comes in: the software structures the entire procure-to-pay process and automates approvals from purchase request to invoice clearance—ensuring cost transparency, budget control, and full compliance.
