Market-optimized industrial heat. Cheaper than gas. Without the risk.
Lower heat costs, reduced CO₂ emissions and a reliable energy supply: ENERGYNEST power-to-heat solutions enable industrial companies to electrify process heat at or below the cost of natural gas.
Electrifying industrial heat takes more than replacing fossil fuels with electricity. It requires managing power price volatility, ensuring 24/7 availability and protecting operational reliability. Our systems deliver heat only when electricity is economically advantageous — while existing boilers remain available as backup.
By acting early, companies reduce exposure to gas price volatility, rising CO₂ costs and regulatory pressure and turn electrification into a financially sustainable infrastructure upgrade rather than a risk.
Does our power-to-heat solution fit your business?
- Your annual heat demand exceeds 5 GWh
- Sufficient grid connection capacity is available (around 1 MW per 5 GWh of demand)
- You want to reduce costs while cutting CO₂ emissions
- Process heat or steam is required from approx. 120 °C up to and beyond 300 °C
- You are looking for a dependable, lower-cost alternative to fossil-based heat
How we make electrification easy for you:
- We analyze your heat demand and energy data and provide a first economic feasibility check.
- We design your optimized system configuration, including storage, power-to-heat and all required technical components. We model savings under real energy market conditions and power price volatility.
- We deliver your solution either as Heat-as-a-Service (zero CAPEX) or as a turnkey EPC project.
Your power-to-heat system. Done right.
Upgrade your thermal infrastructure and existing boiler with an integrated system combining modular ThermalBattery™ storage, electric heaters and optional steam generators or heat exchangers.
Electricity is converted into heat only when it is cheaper than gas, stored and delivered on demand — ensuring reliability, flexibility and long-term cost competitiveness. Our modular system integrates with your current infrastructure, allowing you to switch between electricity and gas based on price, while maintaining the reliability of your existing assets.
Optimize fossil fuels and power your processes with electricity!

Our integrated power-to-heat solutions deliver a lower-cost, reliable alternative to fossil-based heat — without exposing your operations to market, performance or investment risk.
Why electrified industrial heat works
We’ve done the math.
ENERGYNEST solutions combine electrification, thermal storage and market optimization into a single, integrated system: designed to deliver industrial heat at lower cost than natural gas, without increasing operational risk.
Instead of relying on average electricity prices, we use electricity only when it is economically advantageous, store heat and deliver it when your process needs it. This turns volatile power markets and rising CO₂ prices into a stable, predictable heat supply.
Proof that cheaper-than-gas heat works
Case example: 10 MW hybrid heat system (electricity, gas, thermal storage), Germany
This example shows how combining power-to-heat, thermal storage and market optimization turns electricity price volatility into stable, lower-cost industrial heat.
Instead of replacing gas entirely, the system uses electricity only when it is cheaper than gas, stores the heat and supplies it when needed — while gas remains available as backup.
What this system delivers
- Operational impact: 52% electrification of heat
- ESG impact: 2,700 t CO₂ reduction per year
- Energy arbitrage: Heat cost reduced from 70 €/MWh to 24 €/MWh
- Bottom line impact: Annual savings of €2.0 million
- Speed to ROI: Payback in 2.9 years
The more flexibility is added through storage and market participation, the cheaper the delivered heat becomes.
ENERGYNEST systems typically electrify 30–70% of heat demand while delivering 50% fuel cost reduction — without increasing operational risk.
How your savings are created
ENERGYNEST systems generate savings through two compounding mechanisms:
What this system delivers
1. Reducing heat procurement costs
We replace part of your gas heat with electricity only during low-price market windows. Your average heat cost drops.
2. Generating additional income
Your thermal storage becomes a flexible grid asset. When the grid needs flexibility, the system can offer demand response, participate in balancing markets and even generate revenue without producing heat. Your system earns money while generating heat.
Savings are created by market mechanics, every day.
How we configure your solution
With a few data points, we can tell you how much we can save vs. natural gas or your current heat source.
We design every system to deliver measurable cost savings, stable heat supply and reduced CO₂ emissions — without exposing your operations to new technical, market or investment risk.

Why act now
Your heat is your biggest operating cost. We turn it into a controllable, lower-risk cost base — and a source of value. Industrial heat is no longer just a cost. It becomes a controllable asset.
Unlock new value
Turn flexibility into revenue.
Your thermal storage becomes a grid asset, generating additional income through balancing and flexibility markets without affecting production.
Take control of your heat costs
Stabilize your cost base.
Electrify heat only when electricity is cheaper than gas and store it for later use — reducing exposure to volatile fuel and CO₂ prices.
Become more resilient
Hedge fuel and market risk. Fuel switching and storage protect you from global LNG price swings, grid congestion and regulatory shocks.
Secure your competitive edge
Build cost leadership into your production.
Lower, more predictable heat costs directly improve margins, pricing power and long-term competitiveness.
