Case Study Amba Operations

Amba Operations GmbH – Cost Efficiency through the reev Electricity Tariff

For a large-scale project in Nuremberg, Amba Operations was looking for an economical and future-proof solution to reduce energy costs and avoid expensive load peaks.

Economical. Sustainable. Future-ready.

Amba Operations GmbH is a full-service provider for charging infrastructure based in Munich. For the past six years, the company has been planning, installing and operating charging stations in semi-public environments – from small business sites to complex depot solutions. With more than 2,500 charging points under management, Amba supports the professionalisation of electric mobility, combining strong technical expertise with a clear commitment to sustainability.

Challenge: rising energy costs and high administrative effort

As part of a client project in Nuremberg, Amba Operations faced the challenge of reducing operating costs for the charging infrastructure while making energy usage more efficient. Until then, electricity procurement was based on traditional fixed-price tariffs — resulting in high administrative workload and limited transparency.

A particular issue were the RLM-based demand charges: in larger installations, electrical power is continuously measured, and high load peaks directly lead to significantly higher costs. Amba was therefore looking for a solution that was economical, automated and fit for the future.

Solution: the reev Electricity Tariff – intelligently integrated into the reev Platform

Amba Operations decided to use the reev Electricity Tariff for the customer project at the Nuremberg site. The dynamic tariff is based on the quarter-hourly electricity exchange prices and is controlled directly via the reev platform.

Charging processes are automatically controlled via the integrated reev Energy Management System (EMS), which not only prevents costly load peaks but also adjusts the charging power to the current price situation.

A prerequisite for using the reev Electricity Tariff is the installation of a smart meter (iMSys or RLM meter) that allows for quarter-hourly billing. This ensures that electricity is consumed precisely when it is available, cost-effective and particularly green — for example during periods when a high share of renewable energy is fed into the grid.

This approach not only shifts energy consumption into economically favourable time windows, it also directly improves the CO₂ footprint of the companies whose charging points Amba operates.

Project Overview

• Location: Nuremberg, Business Tower underground car parks 1 & 2
• System: 38 AC charging points
• In operation since: August 2025
• Annual consumption: approx. 50,000 kWh p.a.
•Savings: up to 30 % lower energy costs
•Technology: RLM metering, dynamic tariff model

Results: measurable cost benefits & higher operational efficiency

By combining the reev Electricity Tariff with the reev Platform, energy costs at the Nuremberg site were significantly reduced.
While traditional fixed-price tariffs allow little flexibility, the dynamic tariff takes advantage of price fluctuations — sustainably lowering procurement costs.

The outcome:
• Up to 30% lower energy costs
• Optimised load management through automated control
• No additional effort required for monitoring or intervention

For Amba Operations as the operator, this results in a noticeable increase in efficiency in daily operations.

Sustainability: 100% renewable energy & eligibility for funding

The reev Electricity Tariff is based entirely on 100% renewable energy generated in Germany.
This not only strengthens the sustainability profile of the projects, but also meets a key requirement for eligibility in many public funding programmes for charging infrastructure.

Amba Operations and its clients therefore benefit twice: from lower energy costs and a measurably improved environmental balance.

Outlook: potential for further projects

Following the positive results in Nuremberg, Amba Operations is evaluating the use of the reev Electricity Tariff in additional projects — wherever the technical conditions are met.
In the future, PV systems and battery storage solutions are also planned to further integrate on-site energy generation with consumption.

“The reev Electricity Tariff is a real game changer for us. We reduce energy costs, cut administrative effort and make efficiency measurable – all integrated within one system.”
