More power storage to alleviate PV curtailment points in Greece


“The market danger is proscribed due to the feed-in-tariffs (FiT) and feed-in-premiums (FiP) fashions that assure the fee of (all) power produced. This is modified. The market routes now by cPPAs (company energy buy agreements) and merchants. This means extra danger for the investor,” Kapellos added.

National renewable power help schemes equivalent to FiT and FiP have change into one of many predominant drivers of the nation’s photo voltaic market, stated Ulrich Laumanns, mission supervisor of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), “together with value reductions. of photo voltaic PV modules.”

Laumanns added that whereas nearly all of put in photo voltaic capability in Greece comes from auctions organized by the Regulatory Authority for Energy, the influence of self-consumption schemes is “very small”.

Regarding the state of the marketplace for energy buy agreements (PPAs) and its predominant drivers, Evangelos Gazis – head of southeast Europe at Aurora Energy Research says that there’s “excessive competitors within the conventional CfD auctions leading to decrease costs, and better willingness to pay from trade defaulters, have pushed curiosity in PPAs throughout the area.

In some circumstances, equivalent to Greece, PPAs permit the grid utility course of to be fast-tracked, creating an “overheat available in the market”, Gazis defined. He added that lenders are nonetheless reluctant to finance tasks which are totally business and require some type of long-term earnings stability.

More ranges of management

One of the continuing challenges that has arisen this 12 months is the problem of curtailments, which Gazis and Kapellos highlighted.

Curtailments in 2023 are estimated at 2-3% of complete RES manufacturing and are anticipated to extend this 12 months because of extra RES. [renewable energy sources] (anticipated 2.5 GW in 2024 in comparison with 2.1 GW in 2023),” defined Kapellos. With the elevated penetration of renewable power within the energy combine, the curtailments for renewables in 2024 – throughout the first 4 months – have already exceeded the numbers of 2023, as mentioned in one of many cowl options of PV Tech Power 39.

One resolution to lowering congestion comes by power storage, Kapellos defined, though funding within the expertise continues to be a couple of years away.

“Energy storage is a minimum of one a part of fixing the constraint challenge. The market lacks power storage and a couple of BESS auctions (~1GW) to help it (RRF) have already taken place. Energy storage is missing and the brand new investments on this path within the subsequent two to a few years. The elevated penetration of power storage will scale back the constraints and even present room for added electrical house (phrases of connection) in particular areas within the nation.

Limited grid capability

Curtailment points aren’t solely one of many largest challenges in Greece, however in the entire of Southern Europe, Gazis defined. He additionally highlighted the danger of value cannibalization and a “sluggish course of to get grid connection” as the largest challenges for the area’s photo voltaic PV trade.

Laumanns additionally raised the problem concerning the state of the nation’s grid. The restricted capability of electrical energy networks to soak up new renewable power is the largest problem, added Laumanns. “This would require vital reinforcements of the present community in addition to the large-scale deployment of power storage programs.”

Faster deployment and elevated help for power storage may ease the containment points whereas serving to stabilize Greece’s grid.

“Greece must strengthen its electrical energy networks, together with connections to different international locations. Investments in power storage and sector connectivity (use of renewable electrical energy eg for electrical autos , warmth pumps, electrolysers) must also be supported,” added Laumanns.

Streamline the licensing course of

In phrases of coverage adjustments to additional help photo voltaic PV development within the area, Gazis says: “[A] extra streamlined licensing course of, extra readability on rules concerning static curtailment (injection restrictions), readability on potential caps and charges for dynamic curtailment,” in addition to “readability of regulatory frameworks and potential help for battery storage, to allow wider deployment of photo voltaic. “

New applied sciences (agriPV, FPV and inexperienced hydrogen)

The implementation of recent applied sciences in Greece continues however in several steps. Laumanns defined {that a} help scheme for floating photo voltaic pilot tasks has been introduced by the Greek authorities.

“For inexperienced hydrogen, there’s a vital potential in Greece and a few tasks are already being developed with EU funding. A nationwide help scheme for inexperienced hydrogen pilot tasks is presently being ready. However, a devoted authorized framework for all these applied sciences doesn’t but exist,” added Laumanns.

The influence of inexperienced hydrogen on photo voltaic PV is plain, and will deliver between 24GW to 34GW of put in capability only for the aim of producing electrical energy to energy these electrolysers. This was highlighted in a visitor weblog revealed earlier at present by Panos Kefalas, Southeastern Europe analysis knowledgeable at Aurora Energy Research, who wrote concerning the potential influence of inexperienced hydrogen on photo voltaic PV in Southeastern Europe.
