Major European companies with considerable interests in energy exchanges abroad are now seeking to represent local industrial producers for demand response services in Greece’s balancing market.
Two major international players, currently assembling new related divisions in Greece, have already approached Greek producers to take on their representation.
Demand response system entry into Greece’s new balancing market is expected to begin within 2021, barring unexpected developments.
Once launched, foreign representatives will be able to assume demand-response, green-aggregator roles in Greece, offering balancing services to the system.
Power grid operator IPTO, in its effort to ensure grid stability, will be able to utilize the flexibility major-scale electricity consumers are capable of offering.
Forecast inaccuracies by green aggregators between November 1 and February 14 cost the RES special account a total of 7.7 million euros, RES market operator DAPEEP’s head official Yiannis Giarentis has alleged in a letter to RAE (Regulatory Authority for Energy) chief executive Thanassis Dagoumas.
This cost arises as green aggregators are not charged for their discrepancies. Instead, amounts they return are limited to sums received through the market at day-ahead market price levels.
Green aggregators are not making any effort to improve their forecasts as, under the current rules, they do not shoulder the cost of discrepancies, the RES market operator head official explained in his letter.
On the contrary, existing balancing market regulations enable green aggregators to maximize profits at the cost of the RES special account, a situation that RAE must investigate, Giarentis pointed out.
The DAPEEP chief, in his letter, has called for an amendment to a related law, ratified in 2016.
Today marks a historic day for the country’s renewable energy sector as RES stations begin their gradual departure from the security of fixed prices and start facing market challenges for payment of production either alone or through green aggregation arrangements.
RES stations with feed-in tariff agreements will, as of today, need to submit their Day-Ahead Schedule production offers for the next day, as is required of thermal stations.
For the time being, these offers will not concern payments for RES stations but, instead, be limited to their projected output.
Energy aggregation enables a group of companies or local institutions to partner together to buy energy from a single developer, or multiple developers, at smaller volumes while retaining the economic advantages of a high-volume purchase.
At present, 103 RES stations offering a total capacity of approximately 560 MW are obligated to operate through Day-Ahead Schedules. Of these, 455 MW are wind energy facilities, 77 MW are solar energy units, and the remainder concern other RES technologies.
