Abstract

Las instalaciones de autoconsumo fotovoltaico (ACFV) han aumentado de forma exponencial en el sistema eléctrico español desde 2021. Estas instalaciones y los sistemas de almacenamiento acoplados a ellas se han beneficiado también de importantes ayudas públicas durante el mismo periodo, las cuales han podido afectar tanto al desarrollo del sector como a la dinámica competitiva en el ámbito energético y en otros mercados. El estudio analiza las diversas ayudas públicas ofrecidas a nivel estatal, autonómico y local en forma de subvenciones, deducciones y bonificaciones. Se evalúa su impacto sobre la penetración del ACFV y, a partir de ahí, se valora su efecto sobre la competencia. Para reforzar la eficacia y los efectos procompetitivos de estas ayudas, así como para minimizar posibles distorsiones competitivas, la CNMC recomienda, primero, reforzar el marco institucional y la coordinación entre administraciones, asegurando que la intensidad de las ayudas combinadas no exceda un determinado umbral, instaurando soluciones de ventanilla única y agrupando incentivos. Segundo, se propone definir las ayudas en términos de cuantías fijas unitarias, así como reevaluar regularmente las áreas prioritarias susceptibles de apoyo público. Tercero, se plantea acelerar el acceso a las ayudas, agilizando su tramitación y la concesión de oficio, ampliando los sistemas de anticipos de subvenciones, concentrando las bonificaciones en el primer año y valorando el uso de instrumentos financieros.
