Flexible Balancing Services

Demand, Generation and Storage.

What are Electricity Balancing Services?

Electricity balancing services bring together the actions of consumers, producers, and storage assets across different timeframes to support the power system. Their purpose is to maintain the balance between generation and demand, ensuring system stability and security of supply. REE Servicio de Balance.

Participants generate additional revenue by modulating their consumption and monetizing their flexibility, while the system operator gains valuable tools to manage peak demand and optimize network planning.

It supports the integration of renewable energy sources and strengthens the participation of consumers and producers in the energy market by aggregating offers and enabling more flexible market mechanisms.

Who can take part in balancing services?

As demand and storage participation in balancing services becomes available, many consumers will be able to aggregate their flexible consumption and actively participate in the market.

For instance, facilities that can adjust their consumption for at least one hour with a 15 to 30-minute notice period.

Flexibility can be achieved in multiple ways, such as turning production lines on or off, managing water pumps, or adjusting temperatures in HVAC systems, freezers, furnaces, and boilers.

How can you participate in Balancing Services?

Through a Balancing Service Provider (BSP). The minimum bid size is 1 MW, and you can participate either individually or through aggregation with a representative. Representante.

Providing these services requires adapting your facilities and certifying their capabilities.

We support you in identifying your flexibility potential and equipping your installations with monitoring systems, making it easy for you to participate.

Balancing Service Types

Balancing services vary across different time horizons, from several hours ahead of energy delivery to real-time operation.

Secondary Control Reserve

Secondary Control Reserve: designed to maintain the balance between generation and demand, it is automatically activated and operates within a timeframe of 20 seconds to 15 minutes.

Replacement Reserve Balancing Energy

Read more

Replacement Reserve Balancing Energy: a service that activates active power reserves to correct imbalances between generation and demand identified after the intraday market closes, while restoring or maintaining frequency restoration reserves through both automatic and manual activation.

It is manually activated within 30 minutes and managed via the European LIBRA platform.

Tertiary Control Reserve

Capacity Reserves: the regulation establishes two types of capacity auctions—main auctions, held annually with a five-year delivery period, and adjustment auctions, also held annually, with a 12-month service period.

Renewable energy aggregation through long-term contracts.

Directly from producers to direct market consumers, tailored to your energy needs.

Balancing Service Provider (BSP)

Read more

Balancing Service Provider (BSP): An entity that delivers balancing services via one or more qualified scheduling units and is responsible for the settlement of balancing energy.

Balancing Services Provision via Scheduling Units and Control Areas

Read more

Balancing services are provided at the level of the Scheduling Unit, with a minimum bid size of 1 MW. This threshold can be met through the aggregation of multiple installations that comply with the required criteria.

A key development concerns demand and storage, which require dedicated scheduling units to enable their participation in balancing services, while maintaining the Market Participant as the asset owner. This also applies to storage systems. For secondary control reserve, service delivery compliance and settlement are managed at the Control Area level.

Balance Responsible Party (BRP)

Balance Responsible Party (BRP): The entity responsible for imbalance settlement and system balancing. A key principle of these balancing conditions is to ensure equal access for all providers to the same balancing products and services, regardless of the type of installation, provided they have completed the relevant qualification process.

Testing Simplification

Read more

Installations may be integrated into a scheduling unit qualified for balancing services without having completed all specific service tests, provided that a sufficient share of the unit’s installed capacity has already passed the required qualification tests.

This enables faster integration of new assets, as long as their capacity does not adversely affect service delivery. It is especially beneficial for incorporating smaller demand-side installations as balancing service providers.

They are at the heart of the energy transition. To participate in the market, they need advanced technological tools and the right infrastructure to enable secure data exchange and access to the resources and services the market offers.
