100% renewable electricity for businesses is an electricity supply backed by Guarantees of Origin, which certify that an amount of energy equivalent to your consumption comes from renewable sources. With ACCIONA Energía, you can choose different pricing options (fixed or indexed).

Switching supplier is done without interrupting your electricity supply: we’ll ask for your supply point details (CUPS) and a recent bill.

Switching to renewable electricity helps you move forward with decarbonization goals and strengthens the traceability of energy consumption across your organization.

Main reasons:

• Renewable attribution through Guarantees of Origin (useful for reporting and internal policies).

• ESG alignment: matching electricity consumption with climate commitments.

• Regulatory and market readiness: meeting requirements from customers, tenders, and supply chains.

In addition, the energy transition is an opportunity to improve competitiveness, as more sustainable companies are better positioned to respond to regulation and market expectations.

Companies that adopt renewable electricity position themselves at the forefront of sustainability. This not only reflects responsible management, but can also have a direct impact on competitiveness.

In a business environment that is increasingly aware of environmental challenges, companies implementing solutions such as renewable electricity for SMEs or for industrial sites may be better placed to win environmentally conscious customers and meet regulations that require emissions reductions.

One of the most important aspects when contracting renewable electricity for businesses is ensuring that the energy you consume comes from certified renewable sources. A Guarantee of Origin certifies that the electricity associated with your consumption has been generated from clean sources such as solar, wind, or hydro.

This certificate is not only a guarantee for your business—it also adds value by evidencing your commitment to the environment.

For offices and service businesses, switching to renewable supply is often one of the most straightforward actions to decarbonize electricity consumption without changing onsite installations.

You can also complement your supply with:

• Energy efficiency (lighting, HVAC, controls).

• Monitoring to understand peaks and consumption patterns.

• Electrification (e.g., heat pumps) where applicable.

Companies with high energy consumption-such as industrial sites or franchise networks-can benefit from renewable electricity tariffs designed for large consumers. These options aim to offer competitive pricing without compromising sustainability.

By contracting renewable energy to reduce a company’s carbon footprint, businesses not only meet environmental requirements, but can also benefit from more stable and predictable pricing-supporting long-term financial planning.

Contracting renewable electricity for your business means changing or defining your supply contract with an energy supplier and choosing the pricing model that best fits your consumption profile.

What we need to prepare a proposal:

• CUPS (Universal Supply Point Code) and the address of the site(s).

• A recent bill (contracted power, tariff, consumption).

• If you have multiple sites: a list of CUPS and estimated consumption per site.

Step-by-step process:

1. We collect your data and objectives (cost, predictability, sustainability, multi-site).

2. We analyze your profile and propose terms.

3. We manage the contractual switch and administrative registration.

4. Your supply continues as normal and you are billed under the new contract.

Yes. Switching supplier or contract type is an administrative process and should not interrupt supply. You typically only need the CUPS and a recent bill. Timelines may vary depending on your distribution company and the current contract status of the supply point.

Typically: CUPS, the customer’s tax details, the supply point address, and a recent bill to review contracted power, tariff, and consumption. If it’s multi-site, a list of CUPS per location is recommended and, if available, consumption history to refine the proposal.

Our digital products include a fixed-price tariff and an indexed-price tariff. For high consumption volumes, other long-term options may also be considered.

A Guarantee of Origin certifies that an amount of renewable electricity equivalent to your consumption has been generated and allocated accordingly, providing verifiable evidence to support your sustainability claims and reporting.

It can influence your energy strategy, but your final cost depends on the pricing model, contracted power, your load profile, and market conditions. If your goal is to optimize your bill, renewable supply is often combined with efficiency measures, monitoring, and-where relevant-onsite generation.
