TWS Technology pitches batteries as the missing piece for commercial heat pumps

TWS Technology says pairing battery storage with commercial and industrial heat pumps can cut total electricity costs by 20% to 35% while easing peak demand, grid constraints and solar curtailment. The company is positioning its Max-Pro and Max-Solaris systems for European facilities ahead of The smarter E Europe 2026 in Munich.

Why it matters: - TWS Technology is targeting a big cost problem for factories, hotels, offices and supermarkets that use commercial heat pumps. - The company says adding battery energy storage can reduce total electricity bills by 20% to 35% while also improving resilience and solar use. - The pitch lands as European operators face peak tariffs, grid bottlenecks and tighter building electrification rules.

What happened: - TWS Technology said commercial heat pumps alone can trigger high demand charges, grid capacity limits and wasted solar energy. - The company outlined how its TWS Max-Pro and Max-Solaris battery energy storage systems are designed to work with commercial and industrial heat pump loads. - TWS Technology is promoting the systems ahead of The smarter E Europe 2026 in Munich, where the company plans to show the Max-Pro and Max-Solaris at Booth C1.470.

The details: - TWS Technology says winter electricity costs in Germany can reach nearly twice summer rates, citing Electricity Maps grid data. - The company says hourly power prices often peak from 16:00 to 20:00 and from 04:00 to 08:00, when many commercial facilities need heating most. - TWS Technology says capacity-congested regions face long grid connection queues, and cites an Eurelectric report that says complex approvals can add years to infrastructure timelines. - The company cites Norway as an example, saying grid upgrade files have faced eight-month waits just to get a case manager. - TWS Technology says rooftop solar often peaks at the wrong time for heating demand, with midday generation not matching morning and evening load. - The company cites Electricity Maps data showing 576 hours of negative electricity prices across 104 days in Germany. - TWS Technology says a BESS can shave peak demand by charging off-peak or from midday solar and discharging during expensive hours. - The company says storage can lift solar self-consumption from about 30% to 70% to 80%. - TWS Technology says a 200 kWh-plus system can support critical heating, cooling or cold-logistics loads for 2 to 8-plus hours during a grid outage. - The company says its Max-Pro and Max-Solaris systems use high-power discharge, liquid cooling thermal management and an intelligent energy management system. - TWS Technology says the systems can operate in temperatures as low as -20°C and as high as 50°C. - The company says the technology can absorb multi-pump startup surges in milliseconds and help prevent breaker trips. - TWS Technology says installed commercial and industrial storage costs now typically range from $250 to $450 per kWh, citing BSLBATT market data. - The company cites International Energy Agency wholesale market projections that show a higher European power-price baseline through late 2027 than the 2018 to 2020 period. - TWS Technology also points to stricter EU policy, including the updated Energy Performance of Buildings Directive, as a driver for faster electrification. - The company explains that heat-pump sizing must account for coefficient of performance, battery depth of discharge, round-trip efficiency, degradation and the facility’s full electrical load, not just the heat pump. - TWS Technology says a 400 kW heat load with a COP of 4 would require 100 kW of electrical power. - The company says a 100 kW heat pump needing four hours of backup would require about 400 kWh of usable storage, before accounting for battery margins.

Between the lines: - The message is less about batteries as a standalone product and more about batteries as a financial tool for making heat pumps workable at commercial scale. - TWS Technology is framing storage as a way to turn heat pumps from a pure decarbonization play into a cost-management and grid-management asset. - The timing suggests vendors see an opening in Europe as power volatility, electrification mandates and slower grid upgrades collide.

What's next: - TWS Technology is asking facility operators to request a preliminary evaluation and to discuss custom integration layouts with the company. - The company directs interested customers to its website and email contact for consultations. - TWS Technology plans to meet visitors at The smarter E Europe 2026 in Munich to present the Max-Pro and Max-Solaris systems in person.
