Spanish Plaza Outdoor Communication Power Supply BESS

What is the current situation of the Spanish Bess market?

The current situation of the Spanish BESS market confirms that both of these factors are required to gain market attraction: Despite a high penetration of renewable energy, the Spanish regulatory framework has been lagging and the first BESS projects of significant size have yet to be built.

What auxiliary loads are needed for a Bess project?

Fire safety systems, such as fire alarms, control panels and gas ventilation systems (if present). These auxiliary loads are essential for ensuring the safe and efficient operation of BESS projects. Therefore, providing a reliable power supply for these auxiliary loads is crucial.

Why do companies need a Bess system?

Sustainability: By charging batteries during off-peak hours, when energy is generated using cleaner technologies, and discharging them during peak hours, when more polluting sources are used, BESS systems help reduce companies’ carbon footprint.

How much power is in the Bess pipeline?

According to BloombergNEF, the total capacity currently in the BESS pipeline is around 3GW. However, Red Electrica’s (the Spanish TSO) registry of requested connection capacity, shows that accumulated requests add up to 22.1GW.

Do I need backup power for a Bess auxiliary load?

For certain projects, backup power must be provided for the BESS auxiliary load as required by the BESS supplier or fire codes. Some BESS suppliers mandate uninterrupted power to maintain the operation of thermal management systems, ensuring battery temperatures remain within desired limits to minimize degradation.

What are the technical requirements and financial implications of Bess auxiliary power?

One critical but often overlooked aspect of BESS project development is the technical requirements and financial implications of BESS auxiliary power. In addition to the power required to charge its batteries, a BESS also requires power for its auxiliary loads. BESS auxiliary loads typically fall into the following three categories:
