Domac: No energy transition without much stronger grid investments

Croatia is investing only half as much in the electricity network as Slovenia and Austria, said Managing Director of North-West Croatia Regional Energy and Climate Agency (REGEA) Julije Domac. He warned that without an acceleration in grid investments, there are no renewable sources and no energy transition.

Croatia is about to overcome one of the biggest obstacles to investments in green energy, with its proposed methodology for the grid connection fee. However, there are several more bottlenecks in the sector, and they mostly also concern the electricity network.

The grid is apparently not among priority segments in Croatia, which depends to a large extent on electricity imports. The situation is similar throughout the Balkans and Europe, and beyond, and the basic question is who will cover the expenses as well as which projects are the most important for enabling the deployment of renewables. Among other difficulties, the administrative capacity for permitting for grid improvements and expansion is too weak, alongside complex environmental and spatial planning requirements.

Managing Director of REGEA Julije Domac outlined his view on the matter in a LinkedIn post. “Without an electricity network, there are no grid connections, no RES, no transition… There is more than 13 GW of solar and wind power projects under development today, but the network cannot integrate it without accelerated investments,” he wrote.

Grid operators reacting with emergency measures instead of long-term strategy

The free capacity in the power distribution grid is estimated at 3.7 GW, but a large part is in areas with low interest for investing, Domac pointed out. Of note, he is also Croatian President Zoran Milanović’s special advisor on energy and climate.

“In the coastal area and Dalmatia, where the resources are the best, the network is near the maximum load in many parts – it means a malfunction of one element could jeopardize the system’s stability. To avoid that, the operators are already often turning to emergency measures in dispatching now: shutting down parts of the network, redirecting flows, pausing works. It is ‘putting out fires’ – and not a long-term strategy,” the head of REGEA said.

The regulated income from tariffs limits investments as the transition’s urgency isn’t acknowledged

Domac stressed that Croatia is investing less than EUR 20 per customer per year, only half as much as Slovenia and Austria. In his opinion, the tariff-based methodology is limiting investments. Namely, Croatian Transmission System Operator (HOPS) and HEP-ODS, the national distribution system operator, are funded through regulated income under the Croatian Energy Regulatory Agency (HERA), and the mechanism doesn’t acknowledge the urgency of the transition, according to the energy expert.

Another point is delayed digitalization, as Croatia has a much lower share of smart meters than neighboring Slovenia, where it surpassed 99%, or Italy, where the level is around 95%, he underscored. There is no domestic market for flexibility and no contracts with batteries and with consumers that could help ease the pressure on the grid, Domac claims.

In addition, he highlighted the sluggish grid connection procedure, saying it lasts ten years for wind power plants and four years for photovoltaics, the most in all European Union.

Grid connection costs can be covered with EU funding, green bonds

Domac is recommending to the authorities to introduce temporary connection points, with a controlled power delivery – limited until network enhancements are completed. HERA did envisage such a possibility in its draft methodology.

The grid connection fee for renewable electricity plants should be abolished, which was already promised, Domac recalled. It is an obstacle blocking 60 projects for 3.5 GW in total, he noted. It is the grid operator that should bear the cost and, aside from the tariff items, it can finance them through EU funds and green bonds, like most member states do, Domac added.

He expressed the belief that ten or so most important grid interventions should be accelerated – transformer stations and transmission lines in particular and especially in Dalmatia. Pilot projects for batteries and flexibility would pave the way for more grid connections without the wires, and public procurements need to be streamlined as well for works worth up to EUR 1 million, for instance, so that the replacement of one transformer doesn’t last twelver months, Domac asserted.
