The German energy market has experienced a dramatic development in recent years, which led to significant distortions, especially among discount electricity providers. immergrün Strom stands as an example of the challenges faced by consumers and companies. The list of problems ranges from unlawful advance payments to sudden delivery stops and massive customer protests. For companies, this means not only uncertainty in energy supply, but also considerable administrative effort in document management, contract monitoring, and communication with suppliers. Automating these processes thus becomes a decisive competitive factor.
The history of immergrün Strom
Immergrün Energie originally positioned itself as a low-cost electricity and gas supplier on the German market. The business model was based on low entry prices and aggressive marketing to quickly gain market share.

The turning point in 2021/2022
The 2021 energy crisis marked a drastic turning point. Exploding procurement costs in the energy markets put many discount providers in existential difficulties. Handelsblatt analyzes the impact of discount electricity providers and highlights the systemic problems of these business models.
Legal disputes and consumer protection
The Federal Network Agency and consumer protection organizations became aware of problematic practices at immergrün Strom. The regulatory measures had far-reaching consequences for customers.
Prohibitions and cease-and-desist letters
The consumer advice center provides information about the Federal Network Agency’s ban on charging unlawful advance payments. This regulatory intervention was intended to protect customers from excessive demands.
In addition, immergrün was issued a cease-and-desist notice by Verbraucherzentrale NRW. A report on the cease-and-desist cites unlawful price increases and short-notice delivery stops as key points of criticism.
| Legal measure | Year | Reason | Impact |
|---|---|---|---|
| Cease-and-desist notice from Verbraucherzentrale NRW | 2021 | Unlawful price increases | Public pressure |
| Ban by Federal Network Agency | 2022 | Excessive advance payments | Payment stop for affected customers |
| Supply stoppages | 2021/2022 | Liquidity problems | Switch to substitute supply |
Impact on business customers
For companies, these developments meant considerable operational challenges:
- Unplanned additional costs due to a switch to the more expensive substitute supply
- Administrative effort for contract changes and provider search
- Documentation obligations to tax advisors and auditors
- Communication overhead with energy suppliers and authorities
Managing these processes requires systematic document management. Automated invoice download solutions help centrally capture and process all energy-related documents.

Automation of energy documents
The complexity of energy supply requires professional document management. Especially with problematic providers like immergrün Strom, seamless documentation is essential.
Automatic retrieval of energy documents
Modern automation platforms can retrieve documents directly from customer portals. Web retrieval features enable the automated download of:
- Monthly advance payment invoices

Alternatives to immergrün Strom
After the experiences with immergrün Strom, many companies are looking for more reliable alternatives. The selection should be systematic.
Selection criteria for energy suppliers
When evaluating alternative providers, companies should consider the following criteria:
- Financial stability: Review balance sheet metrics and company history
- Price guarantees: Fixed prices for at least 12 months
- Contract transparency: Clear notice periods and price adjustment clauses
- Customer service: Availability and response times
- Reputation: Independent reviews and complaint statistics
Regional vs. nationwide providers
Municipal utilities and regional suppliers often offer more stable conditions than nationwide discount providers. Prices are often higher, but planning security is valuable for companies.
| Provider type | Price level | Stability | Service | Recommendation |
|---|---|---|---|---|
| Municipal utilities | Medium–High | Very high | Personal | High priority |
| Regional suppliers | Medium | High | Good | Recommended |
| Established nationwide | Medium | Medium–High | Variable | Subject to review |
| Discount providers | Low | Low–Medium | Often problematic | Caution |
Managing multiple energy contracts
Companies with multiple locations often need contracts with different suppliers. Centralized management of all energy-related documents thus becomes complex.
Finance solutions for automation help process invoices from various suppliers uniformly. All documents flow into a central system, regardless of the sender.
Process optimization in energy management
Beyond pure document management, companies can fundamentally optimize their energy processes. Automation plays a key role here.
Monitoring consumption and costs
Systematic energy controlling requires:
- Regular recording of all consumption data
- Comparison with prior periods and benchmarks
- Identification of anomalies and savings potentials
- Reporting for management and controlling
Operations automation enables the automatic extraction of consumption data from energy invoices and their transfer into analytics tools.
Early warning systems for price changes
Experiences with immergrün Strom show in particular: Unannounced price increases can cause significant additional costs. Automated systems can trigger alerts immediately when changes occur.
Components of an early warning system:
- Automatic retrieval of new documents from customer portals
- Text analysis to detect price changes
- Immediate notification of relevant employees
- Documentation for objection deadlines
The connection features of modern automation platforms link energy portals with internal communication channels such as Microsoft Teams or email.
Optimization of procurement processes
Companies should manage energy contracts proactively rather than reactively. This means:
- Timely termination before automatic renewal
- Comparison offers at least 3 months before contract end
- Documentation of all offers for later evidence
- Systematic evaluation of new providers
Procurement solutions automate these processes and ensure that no deadlines are missed.
GDPR-compliant document management
Data protection is central when automating energy-related documents. Energy documents contain personal and business-critical information.
Requirements for data security
German companies must comply with the following standards when processing energy documents:
- Encryption during transmission and storage
- Access controls on a need-to-know basis
- Audit-proof archiving in accordance with GoBD
- Server location in Germany or the EU
- Data processing agreements with all service providers
Platforms with a focus on data security and German server locations offer advantages here. GDPR compliance should be the top priority when selecting automation tools.
Role-based access control
Not every employee needs access to all energy documents. Differentiated permissions are necessary:
- Finance department: Full access to invoices and payment data
- Facility management: Access to consumption data and technical documents
- Executive management: Read access to overviews and reports
- External service providers: Restricted access only to relevant documents
The future of energy supply and documentation
The energy market is in a state of flux. Digitization and automation will become even more important in the future.
Trends in the energy sector 2026
Several developments shape the current situation:
- Volatile prices due to geopolitical uncertainties
- Regulatory changes to promote renewable energies
- Digital customer portals as standard for all suppliers
- Smart metering for detailed consumption analyses
- Dynamic tariffs with hour-by-hour pricing
These trends significantly increase the amount of data. What used to be a monthly invoice will in future be thousands of data points per year.
Scalable automation
Handling this data flood requires scalable solutions. Manual processes reach their limits. Management solutions for document automation grow with the requirements.
Future-proof automation architecture:
- Cloud-based platforms for flexible scaling
- API integrations with all relevant systems
- AI-powered data extraction even from unstructured documents
- Automatic adaptation to new document formats
- Predictive analytics for cost forecasts
Best practices for sustainable energy management
Successful companies establish systematic processes:
- Centralized data storage: One system for all energy-related documents
- Automation first: Manual processes only where absolutely necessary
- Regular reviews: Quarterly review of contracts
- Documentation: Seamless traceability of all activities
- Continuous optimization: Annual review of the automation strategy
