Key Points
SPACE is E.ON's major IT transformation program modernizing Westnetz's customer service and billing.
Thousands of customers report delayed payments, unprocessed applications, and months-long processing backlogs.
Solar panel operators particularly affected by unpaid feed-in compensation and stuck connection requests.
Project's broad scope across multiple business areas created operational bottlenecks instead of promised efficiency gains.
Westnetz, the grid operator for western Germany, is under pressure after its major IT transformation project called SPACE has created chaos for thousands of customers. The modernization program, designed to automate customer service and billing, has instead caused long processing delays, unpaid invoices, and unresolved cases. Solar panel owners report months-long waits for feed-in payments and stalled applications, raising questions about the project’s execution and timeline.
What the SPACE Project Was Supposed to Do
SPACE is a comprehensive IT transformation program within the E.ON Group designed to modernize Westnetz’s operations. The project aims to create standardized processes and unified systems across customer service, metering, energy data management, market communication, and billing. According to Westnetz’s 2023 and 2024 reports, the program integrated energy data management and metering first, followed by back-office and front-office solutions. The project touches critical areas where customer data, meter readings, invoices, and market processes intersect.
Customer Complaints Mount Over Delays and Unpaid Invoices
Solar panel operators have reported serious problems since SPACE’s rollout. Customers complain of delayed feed-in payments for electricity supplied to the grid, unprocessed applications, and cases stuck in limbo for months. A recent Spiegel report cited thousands of complaints linked to the SPACE project, though independent official confirmation of the exact number was not immediately available. The delays affect households with solar panels, heat pumps, wallboxes, and new metering systems, where proper data processing is essential for payments and connections.
Why the Modernization Backfired
The SPACE project’s problems highlight the risks of large-scale IT transformation in regulated industries. When processes for customer service, metering, and billing malfunction, the impact spreads quickly across interconnected systems. Customers cannot get answers, payments are stuck, and applications languish. The project’s scope—touching multiple business areas simultaneously—appears to have created bottlenecks rather than the promised efficiency gains. Westnetz has not publicly disclosed a timeline for resolving the issues or compensating affected customers.
Final Thoughts
Westnetz’s SPACE project demonstrates how IT modernization can backfire when execution falters. With thousands of customers facing payment delays and unprocessed applications, the grid operator faces reputational and operational damage that could take months to repair.
