The energy transition in a volatile world: how companies can plan for multiple scenarios in 2026

Leave a Comment / Article / By

The energy transition in 2026 is no longer a straight-line decarbonisation story; it is a resilience challenge shaped by war risk, volatile fuel prices, and a moving regulatory target. Companies that plan for a single future will likely be caught out, while those that build flexible, scenario-based strategies can protect margins and keep their transition credible.

Why 2026 feels different

The US-Israel-Iran conflict has already shown how quickly geopolitical shocks can transmit into energy markets, with Brent and European gas prices swinging sharply as Middle East supply routes and LNG flows are disrupted. Reuters reported Brent at $105.33 per barrel in late April, while European gas and electricity markets have also seen large spikes as the conflict raised the risk of tighter LNG supply and higher competition for cargoes.

For companies, the implication is simple: energy transition planning can no longer assume stable input costs or smooth policy implementation. The same investment case that looked compelling at lower fuel prices may now need to survive a prolonged period of expensive power, fragile supply chains, and pressure from customers and regulators to keep decarbonising anyway.

Scenario planning that works

A useful approach in 2026 is to build three to four plausible scenarios rather than a single forecast. For example: a high-price, high-volatility case; a de-escalation case with easing fossil-fuel prices; a regulation-tightening case; and a fragmentation case where rules diverge across the UK, EU, and other jurisdictions.

Each scenario should test the same core questions: what happens to operating costs, capital expenditure, product pricing, supplier reliability, and emissions reduction timelines? The point is not to predict the future precisely, but to identify which investments are robust across several outcomes and which ones only work under one optimistic assumption.

What to prioritise

Companies should focus first on actions that reduce exposure regardless of scenario. These include energy efficiency, on-site generation, demand response, long-term renewable procurement, storage, and tighter procurement contracts with clear pass-through and hedging rules.

It also makes sense to map “transition resilience” alongside physical resilience. That means asking whether a project still works if gas stays expensive, if grid upgrades are delayed, if carbon prices move, or if a key market tightens disclosure rules faster than expected.

Regulatory direction

Regulation is still moving, even if the direction differs by jurisdiction. In the UK, the government has been consulting on transition plan requirements and broader sustainability reporting expectations, while the final UK Sustainability Reporting Standards are now available for voluntary use as the government decides who will be required to report under them.

In the EU, the Omnibus changes have reduced some mandatory climate-transition-plan obligations under CSDDD, but companies in scope of CSRD still need to report on transition plans where they have them, and the reporting landscape remains active and subject to further change. IFRS S2 guidance also reinforces the expectation that companies disclose relevant climate-related transition information, including assumptions and dependencies.

A practical company playbook

A strong 2026 transition plan should do five things:

  • Set investment gates tied to multiple price and policy cases, not a single base case.
  • Separate “must-do” resilience investments from “nice-to-have” decarbonisation projects.
  • Build flexibility into energy procurement, including hedges and contract optionality.
  • Link climate strategy to financial planning and balance-sheet resilience.
  • Refresh the scenario set regularly as geopolitics and regulation evolve.

The best plans will be explicit about trade-offs. For instance, a company may accelerate electrification in one business line while delaying another project until power prices stabilise or grid capacity improves; that is not a retreat from transition, but a more disciplined sequencing of capital.

What boards should ask

Boards should press management on whether the transition plan is still investable under stress. Good questions include: how much of the portfolio depends on cheap gas, what level of electricity price would break the business case, which regulatory changes could accelerate capex, and how quickly the company can pivot if a scenario becomes reality.

They should also ask whether disclosures are consistent across strategy, risk, and finance teams. A transition plan that looks ambitious in sustainability reporting but is not reflected in procurement, capital allocation, or treasury assumptions will not withstand investor or regulatory scrutiny.
