Energy Storage Units – The Key to Energy Independence

The Rise of Energy Storage in the Modern Energy Landscape

The global energy transition is accelerating faster than ever, driven by the need to reduce carbon emissions, integrate renewable energy sources, and achieve grid stability. However, renewable energy – particularly solar and wind – is inherently intermittent. The sun doesn’t always shine, and the wind doesn’t always blow.

This is where energy storage units come in — acting as the critical bridge between energy production and consumption. By storing excess electricity when generation is high and releasing it when demand increases, these systems enable both individuals and energy operators to optimize usage, maintain stability, and reduce dependency on centralized grids.

For INOWATTIO, energy storage is not just about batteries — it’s about intelligence, integration, and innovation.

What Are Energy Storage Units?

An energy storage unit (ESU) is a system designed to capture and store electrical energy for later use. In modern renewable systems, this usually takes the form of lithium-ion or LFP batteries, managed through advanced digital controls and connected to solar PV installations, inverters, and smart meters.

INOWATTIO’s approach to storage goes beyond hardware. It merges IoT devices, cloud microservices, and SCADA-grade control into a unified architecture, allowing precise command, real-time monitoring, and seamless aggregation across thousands of units.

The company’s hybrid architecture combines:

• ARES – SCADA control and command loop
• ORION – capacity and slot management
• HEMERA – real-time data collection
• ARTEMIS – metadata and configuration engine
• NEMESIS – IoT field device for local regulation

This ecosystem enables INOWATTIO to operate as a certified energy aggregator, validated by Transelectrica, Romania’s transmission system operator.

How INOWATTIO’s Storage Units Work

INOWATTIO’s smart storage units combine cloud-based control with local execution to ensure both speed and resilience.

1. Energy Generation and Capture

When solar panels produce more energy than the household or business consumes, the surplus electricity is routed to the storage unit instead of being lost to the grid.

2. Local Optimization (Nemesis IoT)

The Nemesis IoT device acts as the local brain of the system. It receives real-time commands from INOWATTIO’s control center via MQTT, adjusting inverter output, charging or discharging rates, and managing priorities between photovoltaic input, battery level, and consumption demand.

3. Centralized Control (ARES SCADA)

At the operational level, the ARES system communicates directly with Transelectrica using the IEC 60870-5-104 protocol. This allows INOWATTIO to receive dispatch signals for the balancing market and execute them in less than one second.

4. Data Collection and Analysis (Hemera)

Meanwhile, Hemera collects telemetry data every two seconds from all active units. This data is analyzed in real-time to evaluate performance, ensure compliance, and detect deviations from setpoints.

5. Smart Aggregation (Orion)

Finally, Orion aggregates the available capacity of all units — prosumers, industrial sites, or energy communities — into “energy pools.” These aggregated units can then act as a single flexible resource, participating in Romania’s balancing market.

Through this multi-layered system, each battery becomes part of a national virtual power plant, contributing to grid flexibility, energy efficiency, and sustainability.

The Benefits of Smart Energy Storage

1. Energy Independence

With an efficient storage unit, users can store energy during the day and use it at night — dramatically reducing reliance on grid electricity and mitigating the effects of rising energy prices.

2. Financial Optimization

By combining solar power with intelligent storage, homeowners and businesses can lower their energy bills, shift consumption to low-tariff hours, and even generate income by providing flexibility services to the grid.

3. Grid Stability and Flexibility

INOWATTIO’s technology enables distributed units to react instantly to grid imbalances, helping Transelectrica maintain frequency stability and reduce the need for fossil-fuel-based reserves.

4. Sustainability and Decarbonization

Every stored kilowatt-hour of renewable energy reduces the need for carbon-intensive backup generation. At scale, this helps countries achieve their decarbonization and net-zero goals faster.

5. Intelligent Monitoring and Control

All data can be accessed through INOWATTIO’s web dashboard and mobile apps for iOS and Android. Users can monitor real-time performance, visualize savings, and control their units remotely.

From Prosumers to Active Market Participants

Romania’s energy market is evolving rapidly, with regulatory frameworks now supporting aggregators and flexibility operators. INOWATTIO’s validated system allows communities of prosumers — residential users, industrial facilities, or municipalities — to combine their capacity and participate directly in the balancing market.

This shift transforms consumers into energy contributors, opening new revenue streams and strengthening national grid resilience.

INOWATTIO’s role is to connect, coordinate, and optimize these distributed assets through a secure, cloud-native platform that meets the strictest operational standards defined by Transelectrica’s TEL-07.VI ECH-DN/25 procedure.

Technology Meets Security

Because energy data and control signals are mission-critical, INOWATTIO implements advanced cybersecurity protocols:

• VPN-encrypted SCADA communication
• TLS 1.3 with mutual authentication for MQTT
• OAuth2 + JWT token-based access for APIs
• Network segregation through Kubernetes namespaces
• Automatic fallback and LTE/5G redundancy

This ensures that energy commands are secure, traceable, and uninterrupted, even during connectivity loss.

A Scalable Future

With over 22,000 simulated units successfully tested and latency below 1 second per dispatch command, INOWATTIO has proven the scalability and robustness of its aggregation technology.

Its platform is ready to integrate thousands of prosumers, storage systems, and renewable assets — turning Romania’s distributed energy resources into a digitally coordinated ecosystem of efficiency and sustainability.

Conclusion: Empowering Energy Independence

Energy storage is no longer a luxury — it’s a necessity for a sustainable, reliable, and autonomous energy future.

Through smart technologies like Nemesis, ARES, Hemera, and Orion, INOWATTIO empowers both individuals and industries to control their energy destiny — to store power intelligently, use it efficiently, and support the grid collaboratively.

In the age of digital energy, independence is powered by intelligence.
