by
Sistema de agrivoltaica con paneles solares integrados en un terreno agrícola o ganadero

La agrivoltaica combina generación solar fotovoltaica con agricultura o ganadería en una misma superficie. Conoce cómo funciona, los principales tipos de sistemas Agri-PV, qué cultivos y animales pueden integrarse y qué beneficios aporta al uso del suelo y a la producción energética.

CAPEX: what it is and what it includes in a renewable energy project

by

CAPEX is the initial investment required to develop, construct and commission an energy project. In the energy sector, it includes equipment, civil engineering works, electrical infrastructure, engineering and other capital costs essential to the asset’s viability.

Energy self-consumption: what it is, how it works and the different types

by
Self-consumption system with photovoltaic solar panels to generate renewable electricity

Self-consumption enables the generation of electricity to meet all or part of the energy needs of a home, business or industrial facility. Find out how it works, the differences between individual and collective self-consumption, the options with and without surplus electricity, and the main technologies used.

PPA: what is a Power Purchase Agreement and what types exist in the renewable energy sector?

A PPA (Power Purchase Agreement) is a medium- or long-term contract for the sale and purchase of electricity between a generator and a buyer. In the renewable energy sector, it can be structured as a physical, virtual, financial, on-site, off-site or sleeved PPA, depending on the method of delivery, settlement and location of the asset.

Net Metering: what it is and how net energy metering works

Net metering is a compensation system that allows for the accounting of energy consumed from the grid and the surplus renewable electricity that a facility feeds back into it. It is a key mechanism for self-consumption and distributed generation.

O&M: what is operation and maintenance in the renewable energy sector?

by

O&M (Operations and Maintenance) engloba las actividades de operación, supervisión y mantenimiento necesarias para garantizar el rendimiento, disponibilidad y seguridad de una instalación de energías renovables durante toda su vida útil.

LCOE: what it is and how the levelised cost of energy is calculated

by
A calculator, euros and an electric cable to illustrate the calculation of the LCOE and the cost of energy

The LCOE, or levelled cost of energy, enables the average cost of generating electricity over the lifetime of a facility to be estimated. Find out how it is calculated and which variables influence the LCOE of an energy project.

Redispatch: what it is and how it works in the electricity system

by
High-voltage pylons and power lines for grid management via redispatch

Redispatch is an operational mechanism within the electricity system that enables adjustments to generation or consumption in order to manage congestion and maintain grid stability. Find out how it works and why it is important for the integration of renewable energy.
