As the proportion of untimetabled renewable energy being fed into the National Grid increases so the problem of balancing electrical supply and demand becomes more acute.
This problem has negative implications for energy sustainability, affordability and security.
EnergiVault Thermal Energy Storage (TES) is the smartest cooling technology available, complementing and supporting the ever increasing uptake of unpredictable renewables.
SOLVING THE PROBLEM - LOW REFRIGERATING CAPACITY
All refrigeration users will have at some time suffered from insufficient capacity. This can be prevalent in industries where production activity has improved year upon year, or where particularly warm weather has stressed refrigeration plant or event of mechanical failure compromises productivity.
Banking with EnergiVault can irradiate these problems by always having sufficient cooling effect in storage. Withdrawals from the bank will be precisely controlled to combat any peaks or deficits in load handling capability.
EnergiVaults dynamic banking allows unrestricted discharge rates due to EnergiVaults patented Organic Heat Exchanger. A unique feature of the EnergiVault system.
SOLVING THE PROBLEM - LOAD SHIFTING
Peak demand periods attract significantly higher tariffs. The problem is how to shift the refrigeration electrical load out of the peak demand periods and into low tariff time zones.
EnergiVault (TES technology) enables effective Load Shifting. Thermal Energy banking can occur any time of day or night and can be programmed to coincide with low energy tariffs and avoid periods where energy costs are prohibitive.
EnergiVault enables users to enjoy the benefits of financial incentives for this type of support.

SOLVING THE PROBLEM - FREQUENCY RESPONSE
Power Generators in the UK have to ensure that 50Hz frequency is fed into the National Grid at all times in order to reduce the risk of blackout and damage to downstream energised electrical equipment.
Standby generation assets are used to provide support, but their reaction time is too slow to match frequency variations, often occuring in milliseconds.
Virtual power station technology allows remote disconnection of load users and can make available reciprocal energy immediately supporting frequency response in the best way available.
EnergiVault TES technology enables refrigeration users to provide Fast Frequency Response support and to receive the high financial rewards paid by the grid operator.
