Uncertainty Is Not a Reason to Wait. It's a Reason to Act.

Why current market uncertainty around energy prices is the strongest argument for commercial solar.

There is a conversation happening in boardrooms across the UK right now, and it goes something like this:

"We know we need to do something about energy costs and also our carbon footprint. But with so much uncertainty out there, policy changes, price volatility, the net zero debate, maybe we should wait and see how things settle before committing to anything."

It is an understandable instinct. Uncertainty makes people cautious. Caution feels responsible. But in the context of energy strategy (especially for high-consumption businesses) waiting is not a neutral position or a particularly good strategy. By waiting, a business is taking a choice to remain exposed to the very forces creating the uncertainty in the first place.

This article is for Finance Directors, Operations Directors, and Sustainability Managers who are weighing-up the timing of a move to on-site solar generation (or need to convince their board). It sets out honestly what the uncertainties actually are; what we can and cannot predict; and why the case for acting now does not depend on being able to predict the future.

What Are We Actually Uncertain About?

Let's be specific. There are three distinct sources of uncertainty that businesses in energy-intensive sectors are navigating simultaneously, and it is worth separating them.

The first is energy price uncertainty. Wholesale gas and electricity prices have been structurally elevated since 2021 and remain volatile. Price swings in recent years have proved that wholesale markets can move 30% or more within weeks! A mild, windy fortnight can send prices tumbling, while a cold, calm spell pushes them back up.

Geopolitical events such as conflict in the Middle East, disruption to LNG supply routes, shifts in Russian gas flows into Europe etc., can and do change the picture rapidly. Nobody has a reliable crystal ball on where energy prices will sit in 2027 or 2028 and anyone claiming otherwise is not being honest with you or themselves.

Perhaps the biggest uncertainty (and one that has recently come into sharp relief) is energy security. Very simply, this is about energy availability and the possibility of power rationing. It may sound a bit of an exaggerated risk, but it has happened before including across Europe in 2022 when the Ukraine conflict started. And once again, with the current conflict in the Middle East, it is being talked about as a real and imminent risk.     

The third risk is net zero policy uncertainty. The UK government's commitment to net zero by 2050 is legally binding, and the Clean Power 2030 target is government policy. But the path to get there (the specific regulations, reporting requirements, incentives, and timelines that will affect individual businesses) has been, and continues to be, subject to revision. The Climate Change Committee's 2025 progress report found that 61% of required emissions reductions are covered by credible plans, but 39% remain at risk. Market confusion is increasing, with a growing divergence between stated ambition, published plans, and actual delivery. What some analysts are calling a Net Zero Reality Index.

These are real uncertainties. We are not going to pretend otherwise. But uncertainty cuts both ways, and in this case, it cuts much more sharply against inaction than against action.

What Waiting Actually Costs

When businesses describe waiting as a cautious or prudent strategy, they often mean it in the sense of financial caution and not spending money until the picture is clearer. However, there is both an opportunity and a direct financial cost to waiting.

Every month a business continues to purchase all of its electricity from the grid at current commercial rates is a month of full exposure to a market that remains structurally elevated and volatile. For any business that is serious about competitiveness, profitability and resilience, tactical fixes are no longer sufficient. Strategic energy procurement is the only sustainable path to managing the cost risk, commercial risk and operational risk.

Energy has become a material strategic risk for Finance Directors. A typical 200-bedroom London hotel is now seeing annual energy costs approaching £1 million, making it the second largest operating expense after staffing. For cold storage facilities running refrigeration around the clock, or food production sites with continuous process loads the P&L impact is similar.

The other cost of waiting is procurement lead time. A commercial solar project (from initial feasibility assessment through design, planning, grid connection application, and installation) takes time. DNO (grid connection) queue times have lengthened. Planning processes have their own timelines. Businesses that decide to act in eighteen months' time will not have a system operational in eighteen months' time. Businesses that start the conversation now are materially ahead of those who don't.

The Net Zero Direction Is Not in Doubt. Only the Detail Is

It is important to distinguish between uncertainty about direction and uncertainty about detail. On the direction of travel, there is no meaningful ambiguity. The UK is committed to net zero. Sustainability reporting obligations for larger businesses are tightening. Businesses should prepare for ISSB S1 and S2 sustainability reporting standards to become the new framework from 2026 onward. The Carbon Border Adjustment Mechanism, which will affect businesses exporting to the EU, is coming in 2027. Supply chain emissions scrutiny is intensifying. Customers, investors, and lenders are asking harder questions about carbon credentials.

Net zero is not a fad. It is the defining economic transformation of our era, as seismic as electrification or the internet. Treat it as a box-ticking exercise and you will find that markets and reputations have moved on without you.

The uncertainty is in the detail. Exactly which regulations will apply to which businesses, on which timelines, with which exemptions. That detail will continue to evolve. However, businesses that build their energy strategy around waiting for the detail to settle before acting are likely to find that by the time it settles, they are behind the curve. Simply reacting to obligations rather than already ahead of them.

What is already clear is that on-site renewable generation is not going to become a less valuable strategic asset as net zero policy tightens. It is only going to become more valuable, both in terms of the cost savings it delivers and the compliance and reporting advantages it provides.

An Honest Word on PPAs and What They Can and Cannot Promise

A Power Purchase Agreement (PPA) is, in many ways, the most intelligent financial response to energy uncertainty available to commercial businesses right now. But we want to be honest about what a PPA is and what it is not.  

A PPA is, at its core, a long-term agreement to buy the electricity generated by a solar installation on your site at a pre-agreed rate, typically for 10 to 25 years, without any upfront capital outlay. A fixed or indexed rate over the life of the PPA provides certainty and a hedge against volatile energy markets, allowing Finance teams to forecast energy costs with genuine confidence. For businesses that have been hurt by energy price volatility, the ability to know what a proportion of your electricity will cost over the next decade is genuinely valuable.

Think of it like a mortgage. When you take out a fixed-rate mortgage, you are not betting that interest rates will rise, you are buying certainty, because certainty has value in itself. You are accepting that you might pay slightly more than the cheapest available rate at any given moment, in exchange for knowing exactly what you will pay. A PPA works in the same way. You are not trying to time the energy market. You are removing a portion of your exposure to it altogether.

However, and this is important, a PPA rate is not set in stone forever without any movement. The starting unit rate under a PPA is typically fixed until the end of the year in which the agreement begins and thereafter adjusted annually by some index (e.g. RPI) for the remaining period. That indexation mechanism means PPA rates do move over time. What they do not do is spike unpredictably in response to a conflict in the Middle East or a cold snap in January. That is the protection on offer. Not a guarantee of the lowest possible price in every future year, but a guarantee of predictability and insulation from the sharpest market movements.

We cannot tell you exactly what grid electricity will cost in 2030. Nobody can. What we can tell you is that on-site solar generation under a PPA will cost you less than grid electricity on the day you switch it on (typically the PPA rate is 30% to 40% below the grid rate), and that the gap between your PPA rate and your grid rate is highly likely to widen over time rather than narrow.

The Opportunity That Uncertainty Creates

Here is the counterintuitive part. The same uncertainty that makes some businesses hesitate is precisely what makes the opportunity so significant right now.

The private sector is expected to provide between 65% and 90% of the nearly £40 billion needed annually to meet the UK's 2030 clean power target. Investment is flowing into renewable energy infrastructure at a scale and pace not seen before. The financing structures available to commercial businesses (PPAs, lease arrangements, asset finance) have matured significantly. The cost of solar technology continues to fall. The case for on-site generation has never been stronger, precisely because the energy market has never been more volatile.

Understanding your estate's potential and acting strategically delivers results regardless of what policy does next. Waiting for government support means missing opportunities that exist right now through private finance partnerships.

For logistics operators managing large distribution centre rooftops. For food producers running continuous day-shift operations that align perfectly with peak solar generation hours. For cold storage businesses whose refrigeration loads make grid electricity their single largest operating cost. The opportunity is real, it is commercially proven, and it does not require certainty about the future to make sense.

It requires only clarity about the present, and the present is clear enough.

What Eden Sustainable Does

Eden Sustainable is a commercial solar and PPA specialist, certified B Corp, and part of AMPYR Distributed Energy, one of Europe's leading distributed energy businesses. We work exclusively in the commercial and industrial sector, with businesses whose energy consumption, roof or land footprint, and operational profile make solar a financially meaningful decision.

We do not offer certainty about future energy prices, because nobody can. What we offer is a rigorous, honest assessment of what solar can deliver for your specific site,  in terms of generation output, cost reduction, and return on investment. We also offer the expertise to design, install, and support a system built to perform for 25 years.

If you are in logistics, warehousing, food production, manufacturing, or cold storage and you are considering your energy strategy, the best time to start that conversation is before your next contract renewal, before the next price spike, and before your competitors have already made the decision you are still deliberating over.
