Managing a Weak Power Supply

As the stability of local and regional grids comes under increasing pressure, the impact of weak power supplies is hitting some businesses hard. Issues are often caused by short power outages or blackouts – particularly in smaller grid sectors or under island conditions.

In many industrial scenarios, these power fluctuations can halt processes and production. This can have significant effects, including:

  • capital loss, the loss of materials that might be rendered unusable when power supplies drop during a process, or;
  • production loss (sometimes referred to as “dead weight loss”), which is the output lost because processes are interrupted or delayed.

Fast Power Storage with DuraStor®

DuraStor is a smart power storage solution that can help overcome these power supply weaknesses, avoiding capital and production losses. Our modular power storage solution protects against unacceptable short-time voltage fails, and bridges the power supply to safely shut down your critical processes, or even to switch on additional power generators in standby.

Find out more about our DuraStor system, and how it can be customised and implemented for any business.


Customer Stories

A European food producer is based in a rural area, at the geographical limit of their regional grid. They have experienced regular and increasing instances of voltage disruption which, unfortunately, remains within the acceptable limits of their power supply contract.

In this situation, the DuraStor solution is able to iron out those interruptions, providing short term power on demand to help remove short term voltage drops, and keep the machines running and production processes in full flow.


When is Smart Uniterruptible Power Generation Better than Classic UPS?

Mission-critical industrial situations are often invariably protected by conventional uninterruptible power supplies (UPS). Such installations typically combine a battery backup device with an engine driven alternator. This conventional setup has two main drawbacks:

  1. The required battery power often results in wasted amounts of energy storage (e.g. more battery cells than required are installed, to overcome the delay of the local engine starting).
  2. The engine-driven alternator exclusively generates electrical power. The sector-coupled use of the also available thermal power (e.g. combustion heat) is not considered and, as a result, wasted.

Stornetic’s technology offers a different solution, supplying a power storage solution that protects processes or critical resources against short term outage through hybridisation, such as with modern combined heat and power (CHP) plants.

With this set-up, the back-up power solution is complemented by the continuous local production of electrical and thermal power to supply your local demands. This significantly increases the overall economical efficiency, sustainably reducing the CO2 footprint of a business’ energy portfolio.


How it Works

The system, with the inclusion of the smart power setup, may be connected to the external grid where power can be taken from, or even fed back to, the public low voltage (LV) network.

In case of any external grid supply failure, DuraStor ensures a smooth, uninterrupted transition into local island grid supply mode by compensating for any local power mismatches.

In local power supply mode, the CHP provides the required electrical mean power, while DuraStor ensures the quality of the electrical grid parameters by compensating for all volatile power fluctuation and residual loads.

As soon as the external network comes back, the smart power setup can resynchronise and switch back to the public network.

With its dynamic load management features, DuraStor additionally allows businesses to gradually include renewable assets into their local power generation portfolio.
