Frequenz is a German company operating in the renewable energy and clean
technology sector, headquartered in Berlin, Germany. The company focuses on
developing software and platform solutions that enable the management,
optimization, and orchestration of distributed energy resources. As the
global energy landscape transitions away from centralized fossil-fuel-based
generation toward decentralized renewable sources, Frequenz positions itself
at the intersection of energy and digital technology, building the
infrastructure required to make modern electricity grids more flexible,
resilient, and sustainable.
The name "Frequenz" is the German word for "frequency," a fitting reference
to one of the most critical parameters in electrical grid management. Grid
frequency must be kept stable and balanced in real time as supply and demand
shift, and the increasing share of variable renewable energy makes this
balancing act more challenging. Frequenz aims to help solve this challenge
through intelligent software systems.
What the Company Does
At its core, Frequenz develops a software platform and ecosystem designed to
integrate and coordinate distributed energy assets. These assets include
solar photovoltaic installations, battery energy storage systems, electric
vehicle charging infrastructure, and other flexible loads and generators that
are spread across many physical locations rather than concentrated in a
single large power plant.
The company's mission centers on accelerating the energy transition by making
renewable energy sources more controllable and economically viable. By
aggregating and intelligently dispatching distributed resources, Frequenz
enables these assets to participate in energy markets, provide grid services,
and operate more efficiently than they could in isolation. This approach
helps unlock value that would otherwise be lost when renewable generation and
storage operate without coordination.
Frequenz emphasizes an open and collaborative approach to building energy
software. The company has invested in open-source tooling and frameworks,
recognizing that the complexity of the energy transition requires shared
standards and interoperable systems rather than proprietary silos. This
philosophy is reflected in the developer-oriented resources and software
development kits the company has made available to the broader community.
Products and Services
Distributed Energy Resource Management
Frequenz provides a platform for managing distributed energy resources at
scale. This involves connecting to physical hardware such as batteries,
inverters, meters, and charging stations, gathering real-time operational
data, and applying control logic to optimize their behavior. The platform
abstracts away much of the complexity of dealing with heterogeneous hardware
from different manufacturers, providing a unified interface for monitoring
and control.
Microgrid Software and Control
A significant portion of Frequenz's technology focuses on microgrids, which
are localized energy systems that can operate independently or in conjunction
with the main grid. The company offers software that orchestrates the
components of a microgrid, balancing generation from solar panels, storage in
batteries, and consumption by local loads. This enables sites such as
commercial facilities, industrial campuses, and community installations to
maximize self-consumption of renewable energy, reduce reliance on grid power,
and increase energy independence.
Frequenz SDK
The company has developed and released a software development kit known as the
Frequenz SDK. This is an open-source toolkit aimed at developers building
applications for microgrids and distributed energy systems. The SDK provides
high-level interfaces and building blocks for reading data from energy assets,
performing calculations on power flows, and implementing control strategies.
By offering these tools openly, Frequenz lowers the barrier for engineers and
organizations seeking to create custom energy applications without having to
build foundational infrastructure from scratch.
Energy Market Participation and Optimization
Frequenz's platform supports the participation of distributed assets in
electricity markets, including markets for balancing services and frequency
regulation. By aggregating capacity from many small resources, the company can
help these assets act collectively as a virtual power plant. This allows
owners of batteries and other flexible resources to generate revenue by
providing valuable services to grid operators, such as helping to keep grid
frequency stable and responding to fluctuations in supply and demand.
Data and Analytics
The platform incorporates data collection, processing, and analytics
capabilities that give operators insight into the performance of their energy
assets. Real-time and historical data allows for monitoring asset health,
tracking energy flows, measuring financial performance, and informing
operational decisions. These analytics underpin the optimization algorithms
that decide when to charge or discharge batteries, when to draw from or feed
into the grid, and how to schedule flexible loads.
Technology and Approach
Frequenz combines expertise in electrical engineering, software development,
and energy markets. The company builds systems that must operate reliably in
real time, since energy control decisions often need to be made within
seconds or even fractions of a second to maintain grid stability and capture
market opportunities. This demands robust, low-latency software architectures
capable of handling streaming data from physical hardware.
The emphasis on open-source development distinguishes Frequenz within the
energy technology space. By contributing tools and frameworks to the public
domain, the company fosters a community of developers and partners who can
collaborate on advancing distributed energy software. This open approach also
aligns with the broader goals of the energy transition, which benefits from
shared standards and interoperability across the many actors involved in
modern energy systems.
Market Context and Significance
The transition to renewable energy is one of the defining challenges of the
current era. As more solar and wind capacity is installed and as electric
vehicles and electrified heating increase electricity demand, the traditional
model of centralized power generation becomes insufficient. Grids must become
smarter and more flexible, capable of integrating millions of distributed
devices that both consume and produce electricity.
Frequenz operates squarely in this space, providing the software intelligence
needed to coordinate these distributed resources. Germany, where the company
is based, has been a leader in renewable energy adoption through its long
standing energy transition policies. This environment provides both a strong
market for Frequenz's solutions and a wealth of technical and regulatory
experience that informs the company's work.
By enabling distributed energy assets to be managed efficiently, monetized
through market participation, and integrated into a stable grid, Frequenz
contributes to making renewable energy more practical and financially
attractive. This supports the broader goal of decarbonizing the electricity
system and reducing dependence on fossil fuels.
Summary
Frequenz is a Berlin-based energy technology company focused on software for
managing distributed energy resources, microgrids, and battery storage
systems. Its offerings include a distributed energy resource management
platform, microgrid control software, the open-source Frequenz SDK for
developers, tools for participating in energy and grid-balancing markets, and
data analytics capabilities. Through a combination of real-time control
technology, energy market expertise, and an open-source philosophy, the
company works to accelerate the global transition to renewable energy by
making decentralized clean energy systems more intelligent, coordinated, and
economically viable.
