PROJECT · GLASS & CERAMICS

Electrifying process heatacross six manufacturing sites.

A European manufacturer needed to understand where electrification could replace fossil-fired process heat across a diverse production portfolio — and which investments should happen first.

Terravia developed a multi-site pathway combining technical feasibility, energy-system modelling and investment sequencing.

THE CHALLENGE

The question was notwhether to electrify.It was where, howand when.

The company operated six manufacturing sites with different thermal processes, asset ages, electricity infrastructure and production requirements.

Some applications appeared ready for direct electrification. Others required hybrid technologies, infrastructure upgrades or further technology development.

A single technology assumption across the portfolio would have produced the wrong investment plan.

THREE QUESTIONS

  1. 01

    Where is electrification technically viable?

    Determine which thermal processes could move away from fossil fuels without compromising temperature, throughput or product quality.

  2. 02

    Where does it make economic sense?

    Understand how capital costs, electricity prices, gas prices and carbon costs affect the business case.

  3. 03

    What should happen first?

    Sequence investments around asset replacements, grid capacity and the maturity of each technology.

PORTFOLIO BASELINE

Six sites.Six different starting points.

Terravia established a common baseline across the portfolio before comparing technology options.

Each site was assessed at process level to understand where energy was consumed, how heat was generated and which constraints would affect electrification.

BASELINE INCLUDED

  • Thermal energy demand
  • Operating temperatures
  • Load profiles
  • Existing furnace and kiln assets
  • Electrical infrastructure
  • Asset age and replacement cycles
  • Site emissions
  • Production constraints

WHERE TO ELECTRIFY

Not every megawattof heat is equal.

The assessment separated process heat into applications with different levels of electrification readiness.

This allowed the company to focus capital on opportunities where the technology was credible while preserving optionality elsewhere.

NOW

Ready to electrify.

APPLICATIONS

  • Low- and medium-temperature drying

TECHNOLOGY & ECONOMICS

Compare the optionson the same basis.

Terravia screened electrification technologies against the technical requirements of each process before modelling the strongest candidates in greater detail.

Electric Resistance

Mature and flexible electrical heating for suitable thermal applications.

Induction

High-efficiency direct heating for compatible materials and processes.

Electric Furnaces

Full or substantial replacement of combustion-based thermal systems.

Electric Boosting

Additional electrical energy introduced into existing furnace configurations.

Hybrid Systems

Electricity combined with combustion to reduce fossil demand while maintaining operational flexibility.

Industrial Heat Pumps

Efficient electrification for lower-temperature thermal demand and heat recovery.

THE BUSINESS CASE

Electrification changesthe economics of heat.

Replacing gas with electricity changes both capital requirements and long-term operating exposure.

Rather than relying on one energy-price forecast, Terravia tested each technology across multiple futures.

Electricity price

The largest operating-cost driver for many electrified processes.

Gas price

Determines the competitiveness of retaining conventional thermal systems.

Carbon price

Changes the long-term cost of continued fossil-fuel consumption.

Utilisation

High operating hours can amplify relatively small differences in energy efficiency.

Asset timing

Replacing equipment at the natural end of its life can materially improve the investment case.

PORTFOLIO PRIORITISATION

One pathway.Different timing by site.

The six sites were positioned according to emissions impact, technical readiness and investment attractiveness.

PRIORITY 01 · SITE B

Electrify at next replacement.

Mature technology, approaching asset replacement and sufficient electrical capacity.

IMPACT

  • High readiness
  • Strong economics
  • Near-term deployment

PRIORITY 02 · SITE E

Integrate electrification into the furnace rebuild.

The upcoming rebuild creates a rare opportunity to increase electrical contribution without premature asset retirement.

IMPACT

  • High emissions potential
  • Strategic asset window
  • Infrastructure preparation required

PRIORITY 03 · SITES C & F

Deploy targeted measures.

Multiple smaller applications can electrify using mature technologies with relatively limited integration risk.

IMPACT

  • Fast implementation
  • Moderate investment
  • Portfolio-wide learning

PREPARE · SITES A & D

Build the conditions for later conversion.

Major process constraints and asset timing make immediate full conversion unattractive.

IMPACT

  • Grid preparation
  • Pilot opportunities
  • Future decision gates

INVESTMENT ROADMAP

Move now where the case is clear.Prepare where it is not.
