Saving energy is like carrying an adapter
Maybe this has happened to you before, or maybe not, because you’re a forward-thinking person.
You arrive in another country, the hotel is fine, and everything goes according to plan.
You have an important meeting the next day.
Everything is under control.
You take out your phone charger, plug it in, and it doesn’t fit.
You look at the outlet, you look at the charger.
At that moment, you remember that they use a different system in that country. And you forgot the adapter.
Electricity exists. But the system is different.
Something very similar happens in corporate energy.
Many companies believe the issue is resolved because there is a signed contract and a guaranteed supply. But energy isn’t a plug. It’s a changing system.
And the problem isn’t that there’s electricity. It’s not being prepared for how the system works when it changes.
Energy is a changing system, not a stable cost.
Many companies still treat energy as a fixed budget item: they negotiate the contract, lock in the price, and file away the bill until the following year. But the energy market doesn’t work that way. It is volatile. It is regulated. And it responds to dynamics that behave not like rent, but like a financial market.
An ERA Group article on energy costs presents a statistic that should give more than one executive committee pause: the volatility of European gas prices can exceed 100% in very short periods. And although we’re talking about gas, the effect carries over to electricity and associated costs. This is not a stable factor. It is a strategic variable. And this is where the first strategic mistake arises: thinking that having a signed contract means you are protected. A contract does not eliminate volatility. It only defines how you manage it.
Fixed or Indexed Pricing and the False Sense of Control
Many companies are unaware of or oversimplify this decision.
Generally speaking, there are two main energy billing models: fixed-price and indexed.
A fixed price offers apparent stability.
Indexed pricing may be more competitive, but it requires understanding how the bill is constructed.
And this is where one of the biggest disparities arises.
Validating an indexed bill is no trivial matter.
It involves downloading multiple hourly files, cross-referencing them with actual consumption curves, and reviewing line items that aren’t always transparent.
In practice, many companies pay bills that are very difficult to verify accurately.
In practice, many companies pay bills that are very difficult to verify accurately.
We’re not talking about sophisticated optimization.
We’re talking about something more basic: verifying that what you’re paying is correct.
Undetected billing errors can amount to thousands of euros a year.
It’s not a market problem. It’s a control problem.
The real energy risk is dependence.
The market changes every day; that is a fact.
The question is not whether it will change.
The question is how your system is designed to absorb that change.
If your energy structure depends on:
- A single type of contract;
- A single supplier;
- A single purchasing strategy;
- a single supply source;
then the risk isn’t in the price.
It’s in the design.
Because when regulatory conditions change, new mechanisms like CAEs emerge, incentives are modified, or compensation models shift, those who aren’t prepared don’t just pay a little more.
They pay for a long time.
The dependency isn’t visible while the system is working. But when the environment shifts, it becomes a structural cost.
Self-consumption, CAEs, and HVAC systems
When we talk about real energy optimization, there are three areas that many companies are still not analyzing in sufficient depth. These are not tactical measures. They are design decisions.
- Self-consumption: Photovoltaic installations reduce dependence on the grid, improve the carbon footprint, and may qualify for subsidies. They change the company’s strategic position in the energy market.
- ESCs (Energy Saving Certificates): Many companies are unaware that they can monetize energy savings already achieved. Investments with estimated seven-year payback periods can be reduced to three years thanks to savings certification.
- HVAC Optimization: Controlling motors using variable frequency drives and smart controls can generate savings of around 9% of electricity consumption. In a 180-room hotel, that can translate to approximately €50,000 in annual savings, with investments recouped in six months.
If energy is strategic—and it is—the questions to ask are: Are invoices being verified correctly? Has contracted power capacity been optimised? Is energy risk being measured? Have CAE opportunities been analysed? Is there real self-consumption potential with comprehensive financial analysis?
Optimizing energy means being prepared. When you travel with an adapter, the system change doesn’t affect you. The same applies to energy—circumstances change, but design keeps you ready.
If you want to check whether your company is prepared or just coasting along, let’s talk.
