Want investment? Be prepared to prove your energy performance

There was a time when sustainability reporting was largely about demonstrating good intentions.

That time is ending.

Today, some of Europe's largest investors, lenders, auditors, and regulators are asking tougher questions. They want evidence. They want consistency. Most importantly, they want to understand whether the numbers they are being shown can be trusted.

Sustainability is becoming a due diligence issue

The introduction of CSRD is accelerating a shift that was already underway.

Sustainability information is becoming more standardised, more transparent, and more closely examined. Companies are increasingly expected to produce information that can withstand external assurance, much like financial reporting.

This changes the conversation.

It is no longer enough to say energy consumption has improved. You need to show how you measured it, where the data came from, and whether someone else could verify the result.

Why energy data matters

For many organisations, energy sits at the centre of operational risk, carbon reduction plans, and future investment decisions. Investors understand this.

Energy performance influences operating costs. It affects exposure to future regulation. It impacts carbon reporting. It can even influence the credibility of wider sustainability commitments.

As a result, organisations are increasingly being asked to provide evidence rather than estimates. Not because investors suddenly care about meter readings. Because they care about risk.

Auditors are changing expectations

The major accounting firms are investing heavily in sustainability assurance services. At the same time, regulators are making it clear that sustainability information must become more reliable, consistent, and auditable.

Research from IMD examining some of the first CSRD reports found that organisations are being held to a more consistent standard, making sustainability disclosures easier to compare and scrutinise. As a result, sustainability reporting is moving out of the communications function and into the boardroom.

The Dutch Authority for the Financial Markets (AFM) has explicitly stated that CSRD assurance exists to support reliable and consistent sustainability reporting so investors can make informed decisions.

Boards, audit committees, investors, and lenders are all asking variations of the same question. Can we trust the data?

From reporting to proof

This is why energy reporting is evolving into something much closer to energy accounting.

Not simply recording consumption, but creating a structured, traceable, and auditable record of performance. The organisations that will be best positioned for future investment will not necessarily be those making the biggest promises.

They will be the organisations that can prove what is actually happening. Because increasingly, investors are asking the same question as auditors.

"Can you show me the evidence?"

The most expensive energy project is the one you never needed

When people talk about expensive energy projects, they usually mean the ones that ran over budget, or the ones that didn’t deliver the savings promised on the slide deck.

There’s a bigger cost that almost never gets discussed: the infrastructure that should never have been built at all.

The mistake happens long before anyone signs a contract

Right across Europe, organisations are pouring millions into bigger electrical connections, oversized heat pumps, extra plant, and energy upgrades because they believe their buildings need it.

Often, they don’t.

It usually starts innocently enough. A historic design calculation here. A consultant’s estimate there. A generic demand profile borrowed from a similar building. A few gaps in the operational data, filled in with best guesses.

None of these decisions feel reckless in the moment. Each one looks reasonable on its own. Stack them together, though, and you get a business case that sails through the boardroom — built almost entirely on assumption.

By the time anyone finds out, the money is already spent

It’s usually much later that the real operational demand turns out to be a fraction of what was planned for. By then, the capital is already committed. There’s no getting it back.

This is exactly why better technology was never going to fix this. Better evidence is what fixes it.

Measure first. Invest second.

At Dublin Airport, actual operational measurements showed demand was significantly lower than the figures used during planning. That single piece of evidence changed the infrastructure specification before any money was committed, and avoided capital expenditure the organisation never needed to spend.

The cheapest project isn’t always the smartest investment.

Sometimes the smartest investment is the project you never have to build.

Why energy data quality matters more than volume

The biggest problem with energy and carbon data isn’t that it’s missing. It’s what we think is reliable.

Most organisations genuinely believe they have their numbers under control. Spreadsheets, smart meters, and automated reports give the reassurance that everything adds up. But scratch beneath the surface, and you’ll often find gaps, inconsistencies, and figures that can’t be traced back to the source. The data looks solid, but can you rely on it and more importantly, will it pass an independent audit process? When it comes to energy data, quality will always trump quantity.

The illusion of reliability

We live in the era of data. Most of us are surrounded by more information than we can process, and we’ve come to assume that volume equals truth. But we rarely stop to ask where the data comes from, how it’s managed, or what quality checks exist behind it.

Many of the processes we still use to gather and manage data were designed long before digital systems — some even before the advent of the personal computer. Over time, we’ve layered technology on top, automated the routines, and made them faster. But we haven’t always made them better.

This is especially evident in how we handle energy and carbon information. The systems most organisations use are patchy at best, far below the standard we’d ever accept for financial data.

What finance gets right

Executives in well-run businesses expect accuracy, traceability, and confidence in their financial reporting. Every figure is tied to a source. Every record is auditable.

Imagine managing company finances using only monthly bank statements — with no insight into what those transactions comprised, no ledger, and no verification. Most of us would call that unthinkable and predict the business wouldn’t last long. Yet that’s precisely how many are still managing their energy and carbon performance.

Yet, in our experience, most organisations have plenty of data. The problem is that it’s often siloed, inconsistent, outdated or unverified. You’d never accept unverified figures when acquiring a new business. You’d check every assumption, every claim, every piece of supporting data before signing the deal. If anything didn’t add up, you’d walk away. The same scrutiny needs to be applied to our energy data.

Moving from assumption to assurance

The first step is straightforward enough: structure. Following an established framework such as ISO 50001 is a good start. It gives us a system for collecting, validating, and reporting energy and carbon data. But structure alone isn’t enough. Data quality has to be actively managed.

This means having the right systems that make the data visible, trustworthy, and insightful for planning, monitoring, and reporting purposes, as well as validating what’s already there.

Because in the end, sustainability decisions are only as good as the data behind them. Treating energy and carbon data with the same rigour as financial data isn’t bureaucracy — it’s credibility. Because the real risk isn’t having too little data, it’s trusting data that can’t be trusted.

When the grid says no: why energy capacity is becoming a business risk

Electricity demand is rising faster than supply. Networks are struggling to cope, and for many organisations, the promise of full electrification now comes with a hidden constraint: the grid itself. Most companies are investing in electric systems for heat, cooling, and mobility. But every site has a contractual limit on how much power it can draw from the network, known as its Maximum Import Capacity (MIC). Breaching that limit comes with penalties, and getting approval to increase it is becoming harder by the month.

This isn’t a distant challenge. It’s already happening. In many regions, requests for higher MIC are being delayed or rejected because grid capacity is simply unavailable. That means organisations electrifying too quickly — or without understanding their true demand profile — could face costly load restrictions, financial penalties, or even supply interruptions. Without proper planning, forecasting and management, your organisation is at risk.

What if millions of investment can't be supported by the grid?

Electrifying heat or cooling may look like a straightforward decarbonisation win. In reality, it often creates sharp peaks in electricity demand. A cold spell, for example, can send power use soaring beyond contractual limits. Without careful planning, the systems designed to reduce emissions can become a new source of operational and financial risk.

Where resilience begins

On-site generation often tops the list of decarbonisation efforts. But real resilience starts before implementation - it starts with understanding your demand and actively managing it. Knowing exactly how and when your organisation uses energy is the foundation for controlling exposure and planning upgrades responsibly.

Historical load data provides the baseline. Continuous monitoring adds visibility. Together, they reveal how demand shifts through the day and across seasons, and where the opportunities lie to spread or reduce peaks.

For operational leaders, this isn’t just about keeping the lights on. It’s about protecting day-to-day operations, financial stability and the capacity for growth. MIC penalties, unplanned downtime, or network restrictions can all cascade into cost, compliance, and credibility risks.

Clarity before capacity

Installing solar arrays or buying more hardware isn’t the solution. The first step is clarity: knowing what’s driving demand, where flexibility exists, and how to balance electrification with grid constraints.

With the right insight, organisations can plan their decarbonisation journey without creating new risks. Energy resilience becomes part of an organisation-wide strategy, not an afterthought.

Rethinking hot water safety in a net-zero context

In many organisations, compliance with Legionella regulations is a well-established routine: maintaining elevated water temperatures, flushing outlets regularly, and logging the activity. These measures are vital for safety, but they weren’t designed with energy or carbon efficiency in mind.

Domestic hot water systems are often significant energy users, yet their impact is frequently overlooked in broader sustainability strategies. Especially in large or complex buildings, maintaining consistently high temperatures across an entire network can come at a notable carbon cost.

A balance between risk and efficiency

Much of the current approach stems from a desire to avoid risk. Heating water above 60 °C offers reassurance that bacterial growth is being controlled. But this often results in systems running constantly, regardless of actual usage or need. In practice, that could mean heating and reheating water that’s never used, or flushing litres down the drain as part of routine checks.

"It raises a question worth exploring: are all the measures in place today still necessary in every context, or are some driven more by precedent than performance?"

Understanding actual demand, outlet use, and temperature trends may help reveal where adjustments are possible - without compromising safety. But doing so requires the right data and a willingness to reassess long-held assumptions.

A more integrated view

Rather than viewing compliance and carbon as competing priorities, there may be scope to align them. Tools now exist to monitor temperature patterns more closely, control systems more precisely, and target interventions where they’re most needed.

Some organisations are already starting to explore this intersection - using insight to reduce energy use while continuing to meet safety requirements. It’s not about lowering standards, but about working smarter within them.

For organisations aiming to reduce operational emissions, domestic hot water systems may offer more opportunities than previously thought. The question is no longer just how to stay compliant, but how to do so in a way that also supports broader sustainability goals.

Why energy security is now a business-critical issue

Some resources are so fundamental that without them, business comes to a standstill. Labour, capital, raw materials, and information are the obvious ones. Among those raw materials is electricity.

For decades, energy sat in the background—seen as dependable, low-risk, and almost invisible. It was treated like stationery or cleaning products: a routine cost, assumed to be unlimited and unproblematic. That mindset is shifting fast.

Because when the power cuts out, everything stops. The recent blackout at Heathrow and failures across Spain’s national grid made that reality impossible to ignore. Energy isn’t just another input—it’s the lifeblood of modern business. And when it fails, the consequences are immediate: no electricity means no business.

The hidden risk in your operations

Most business continuity plans mention electricity—but usually as a box to tick: a backup generator, maybe an untested system buried in the appendix. What’s often missing is a clear understanding of how and when you actually use electricity. Without that visibility, even minor interruptions can lead to significant disruptions.

And this isn’t just about sudden outages. Rising demand, pressure on grids, and uncertainty around renewables all contribute to a more fragile energy landscape. If electricity is a key input to your operations, as fundamental as money or people, it deserves the same strategic attention.

Energy visibility is risk resilience

You can’t control the grid, but you can control your demand. And that starts with insight. Understanding where energy is used, when it peaks, and where it’s wasted isn’t just about hitting sustainability targets—it’s about keeping your business running.

Reducing unnecessary demand strengthens resilience. It means your operations are less vulnerable to price spikes, infrastructure strain, or supply limitations. It might even mean your critical systems can run on a smaller generator if needed. If your business plans to grow, optimisation of current use means that growth is not restricted by an electrical grid connection, for example, and can be achieved with lower costs.

The businesses that do best in the face of energy volatility are those that don’t leave it to chance. They build clarity around demand, optimise what they control, and act before disruption hits.

Energy security isn’t just about supply. It’s about knowing how your business uses energy—and what happens when it’s no longer there.
