Estore: Demand response for cold storage
Reducing energy bills for cold storage and refrigeration
Intelligent demand response to optimise energy consumption
Reducing the costs of energy-intensive refrigeration
Energy-intensive refrigeration and chilling facilities
are a significant business overhead in a variety of industries. Cold storage operators
in logistics, pharmaceuticals, retail, electronics and food sectors need to minimise
their energy costs, while their energy suppliers want to reduce the impact of refrigeration
on power supply and grid assets.
Engie has developed Estore to meet both these needs.
Estore enables coldstorage facilities to automatically adjust their energy consumption
based on a combination of temperature and price signals without any loss of performance.
At the same time it allows energy suppliers to improve their load-balancing capabilities.
Demand response and load balancing for perfect performance
Estore is a controller for refrigeration systems
that automatically adjusts power consumption in response to price signals from
the grid, without impairing performance of the refrigeration unit.
Estore takes advantage of the natural storage capacity inherent in refrigeration technology
to draw power from the grid at the cheapest rate on the day-ahead market. Its selflearning
algorithms monitor the entire refrigeration process to understand how a freezer or refrigerator
behaves. It then uses that data, alongside price signals from the market, to safely adjust power
consumption. Using Estore, cold-storage operators consume energy at the lowest price while
ensuring temperatures remain consistent and compliant with relevant industry regulations.
Estore can be retrofitted into existing refrigeration and cold storage units, or built
into new machines as a key feature of an energy-efficient design.
Estore is a refrigeration control unit that enables
automatic demand response, with the following features:
Software controller to automatically adjust energy demand in response to grid price signals
Self-learning algorithms that guarantee consistent and compliant refrigeration levels
Cost-effective and compliant cooling
Using Estore guarantees cold storage operators the
lowest energy price for their refrigeration, significantly reducing their overheads
without compromising any aspect of performance.
Energy supply companies that offer Estore to their
customers benefit from greater load balancing capability, helping them to optimise use
of existing grid assets, and ensure continuous supply in the face of growing demand.
Effective load balancing makes it easier for
energy suppliers to integrate intermittent and non-dispatchable generation
into the energy mix, to meet public and political demand for greater use of
renewable energy sources.
