National Regulatory Authority in Energy (ANRE) - Regulatory framework for (i) controllable OPEX and (ii) flexibility services

As part of this project we prepared two specialized studies regarding regulatory best practices pertaining to:

• Controllable maintenance and other OPEX costs

• Flexibility services framework

The first study covered: a multi-point comparison between Romanian DSOs, an analysis of controllable OPEX influencing factors, European best practices in the field (including efficiency factor), an indication of potentially applicable unit costs, efficiency factor estimation methods, simulations of potential factors applied to Romanian DSOs.

The second study looked into: calculation models and principles to fundament grid reinforcement vs. flexibility (CAPEX vs. OPEX), data exchange between TSO – DSO – consumer/ producer considering the existing it architecture and data flows, flexibility platforms (congestion calculation/congestion auctions), DSO perspective analysis of flexibility organisation: procedures, register, platforms.
