Renewable energy 24/7
Use your renewable energy 24 hours a day, 365 days a year for over 25 years
Renewables are intermittent. This means you cannot always rely on them to produce energy when its required. redT’s machines provide the solution by storing your renewably generated energy until you need it.
Video: firming solar at a UK agri-business gives a 10% Internal Rate of Return (IRR, unlevered).
One mid-sized 45-225 redT machine stores 225kWh of energy and discharges 45kW of power for 5 hours. Add more machines to scale up. redT machines handle discharge durations from seconds to days, and power ratings from 5kW to 10MW.
You can save money by using significantly more, if not all, of your on-site generated electricity.
According to our customer data in the UK, by using a redT 300kWh system to store self-generated energy instead of exporting it, a commercial site owner can make a net gain of 8.5p per kWh. An average UK site pays approximately 12.5p per kWh to import electricity whilst being able to export at approximately 4p per kWh.
The average saving in this example is £7000 per year, which does not include additional revenue creating services such as frequency response, grid balancing and energy trading which can also be ‘stacked’ on top of self-generation returns.
This business case is not limited to the UK. Australia, for example, combines some of the highest electricity prices with low-cost solar generation, making self-utilisation of renewables highly attractive. The same is true for South Africa, where demand charges are a significant business cost.

Firming renewables with redT energy storage machines means:
- Cheap, reliable renewable energy
- Additional revenue streams via grid services and energy trading
- Increased energy independence
- Significant savings on annual energy costs
- Hedging against future energy price increases
