Key takeaway: Each Iranian crisis reveals the same structural vulnerability. The Strait of Hormuz concentrates approximately 20% of global oil and about 20% of global LNG trade1. After reducing its dependence on Russian pipeline gas (from ~40% before 2022 to approximately 15% by 20243), Europe became more reliant on imported LNG, a significant portion of which originates from the Persian Gulf. Consequences for industrial prices: gas and electricity remain substantially higher than pre-2021 levels2. Protection will not come from contracts alone, but from real-time management of consumption.

The "perfect storm" seen by finance teams: price increases → margin pressure → deferred investments → loss of competitiveness. The annual EIB Investment Survey (EIBIS), conducted by the European Investment Bank among approximately 12,000 European businesses, has identified energy cost and availability as among the primary investment obstacles cited by companies since 20224. Yet despite the stakes, instrumentation at industrial and tertiary sites remains highly uneven: according to the IEA, deployment of sub-hourly measurement and sub-metering remains partial across a large portion of the global industrial base9.

CRITICAL GEOGRAPHY

Why an Iranian strait threatens your operating accounts

According to the U.S. Energy Information Administration (EIA), approximately 20 million barrels of oil per day transit the Strait of Hormuz — roughly 20% of the world's liquid oil consumption and nearly 30% of oil transported by sea1. On the gas side, the EIA estimates that approximately one-fifth of global LNG trade also uses this passage, with most originating from Qatar and the United Arab Emirates1.

Europe fundamentally restructured its gas mix following Russia's invasion of Ukraine. According to the European Commission and the Bruegel tracker, the share of Russian pipeline gas in total EU imports fell from approximately 40% in 2021 to less than 15% by 20243. In compensation, LNG now represents around 40% of European gas imports, with the United States, Qatar, and Norway as primary suppliers3. All Qatari LNG — the world's third-largest exporter — must obligatorily transit the Strait of Hormuz, with no maritime alternative. This physical dependency explains Europe's sensitivity to Iranian tensions.

Transmission mechanism: historically, major Middle East geopolitical tensions translate into spot index increases (TTF, Brent) within days, which then feed through to industrial consumers' indexed contracts with a lag of weeks to months depending on the pricing formula.

DATA FROM EUROSTAT & ICE ENDEX

The figures finance teams remember

~ ×15

Multiplication of TTF between 2020 levels (≈ €10-15/MWh) and August 2022 peak (above €300/MWh)5.

~ +60 to +80 %

Electricity price increase for average industrial consumers (IC band, 500-2,000 MWh/year) in the EU between 2021 H1 and 20242.

~ ×2 to ×3

Multiplication of EU industrial gas prices (I3 band) between 2021 and the 2022-2023 peak, with partial decline afterward but levels remaining well above pre-2022 period2.

Reading for an industrial site: for a consumption of 500 MWh/month (6 GWh/year) of electricity, a 60% price increase represents, at constant consumption structure, tens of thousands of euros in additional annual costs. The effect is even more pronounced on thermally intensive sites with high gas consumption.

Transparency note. Exact percentage increases depend heavily on the sub-period and consumption band selected in Eurostat databases nrg_pc_203 (gas) and nrg_pc_205 (electricity). We provide conservative ranges corresponding to median industrial averages; highly electricity-intensive sites (IF band) experienced different trajectories, sometimes smoothed by long-term contracts.
OPERATIONAL IMPACT

What lack of energy management costs you

Irregular margins

Operating profit becomes dependent on variables outside company control. Without fixed tariff offset, spot increases hit margins directly. The 2024 EIBIS documents that a majority of surveyed European companies cite energy cost as an obstacle (major or minor) to investment since 20224.

Decarbonization investments delayed

Price volatility complicates ROI analysis for energy efficiency projects: the same investment does not have the same payback period depending on the price scenario assumed. The IEA emphasizes in Energy Efficiency 2024 that the rate of improvement in global energy intensity remains below the desired doubling trajectory by 20306.

Information asymmetry

Energy suppliers have dedicated pricing teams and load profile analysis. Without hourly load curve data, it is very difficult to negotiate beyond standard rates or challenge proposed optimizations. Having 12 months of measured load curve data materially shifts the negotiation dynamic in energy tenders.

OPERATIONAL LEVERS

Three resilience levers to activate now

1. Eliminate the invisible

Public assessments of energy efficiency potential in industry typically estimate savings potential of 15 to 25% at moderate cost (standby equipment, compressed air leaks, drift settings, overheating, over-lighting)7. Putting systems under monitoring enables identification of these items before any major capital investment. On an annual invoice of €500k, this represents €75-125k in direct savings with no major capex.

2. Shift usage across time

On EPEX SPOT, the spread between the cheapest and most expensive hour of the day frequently exceeds €100/MWh, and can reach hundreds of euros on tight days5. Shifting flexible loads (charging, pumping, cooling, certain production) to off-peak hours represents a measurable savings lever, provided you have fine-grained consumption measurement by use. For a site with 20% flexible load, this can represent 10-15% reduction in electricity cost.

3. Reclaim control of contracts

Having a measured load curve enables you to challenge supplier offers: actual consumption profile, peak/off-peak ratio, seasonality. Without this data, the company relies on supplier estimates. Data-driven argument is today the only structural way to rebalance the negotiation. On average, Wattnow customers reduce their tariff margins by 3-8% at the next contract renewal.

PROJECTIONS TO 2030-2035

Two company categories will emerge by 2030

Three structural forces will not weaken. First, electrification of the economy is driving electricity demand: the IEA projects significant growth in EU electricity consumption by 2035 in most scenarios8. Second, critical maritime chokepoints (Hormuz, Malacca, Bab el-Mandeb, Suez Canal) remain vulnerable, as Red Sea attacks since late 2023 have reminded us. Third, extreme weather events affect both production (droughts, hydroelectric declines, thermal plant efficiency degradation) and consumption (air conditioning peaks).

"Invoice" companies

They discover consumption at D+30, on a PDF. They endure each crisis, each peak, each alert. Treasury absorbs shocks. Finance teams observe more than they pilot.

"Management" companies

They visualize consumption in half-hour intervals, detect drifts in real time, react and arbitrate. Energy becomes a managed asset like inventory or cash. They face each crisis with a tangible reaction lever.

QUESTION FOR WATTNOW EXPERTS

Where does your company stand?

Do you know precisely what you consume, hour by hour, equipment by equipment? Have you identified your energy efficiency potential?

FREQUENTLY ASKED QUESTIONS

What your peers ask

Is real-time management really suitable for SMEs?

Yes. Installation occurs without production interruption, entry cost is now accessible for mid-sized companies, and ROI typically runs from a few months to 18 months depending on consumption profile. Monitoring is no longer reserved for large industrial accounts.
How long to see first results?

First savings potential is typically identified within the first weeks of data (overnight consumption, weekends, forgotten equipment). Corrective actions can be initiated quickly and bill impact becomes visible in the months that follow.
Is it useful if I already have a long-term fixed-price contract?

Yes: every kWh saved is saved at your contract price, which mechanically maximizes savings value. Moreover, at your contract renewal, you'll have detailed load curve data to renegotiate based on actual consumption.
What about data security and reliability?

The Wattnow platform is hosted in Europe. Data is encrypted and confidentiality is contractually guaranteed. We apply standard SaaS B2B security practices.
