Written by Christos Kougevetopoulos, head of operations at Wattcrop.

Following the escalating energy crisis in Europe, renewable energy has been a point of focus to help resolve the current situation and provide a safe buffer to the current energy mix. The advantages of renewable energy with regards to providing solutions to the problem are already known, with the main one being the ability for quick deployment and production of clean energy relatively quickly when compared to other forms of energy production. Deployment of such projects also contributes towards a carbo-neutral economy and ensuring the ambitious renewable energy target for the EU of 32% by 2030 is met, or more ambitious targets that are now being considered per the below graph.

Latest Greek auction points to future market realities

The steady reduction in the price of winning tariffs in successive rounds of Greek renewables auctions, capped by the most recent edition in May, has the potential to realign the market in the country.

Over successive auctions held over recent years, Greece has followed most other countries in registering incremental drops in the tariffs awarded to successful projects. 

And May’s (2021) latest 350MW edition of the Greek programme was no exception as successful bid prices dipped down to an average of EUR 37.60/MWh, although falling as far as EUR 32.97 in the case of one project: a 19.3MW solar farm developed by local group Egnatia. 

Other successful bidders included Lightsource bp, in a collaboration with another local developer Kiefer TEK, which secured 20-year contracts for 140MW of solar PV capacity at an average price of EUR 38.50/MWh. Meanwhile, Mytilineos also bagged tariffs for 140MW of solar, at a slightly lower average rate of EUR 37/MWh.

Data analysis is set to transform the energy industry – 4 applications that lead this change

Be Bold. Make the Change. Have a meaningful Impact.

Data analysis can be deployed across the whole energy value chain, regardless of the size of the asset. From large utility scale sites to residential solar and storage, leveraging the power of data drastically cuts costs, enhances the useful life of the asset and saves valuable time to the owner and managing team.

Currently information flow is fractured and involves multiple stakeholders, exchange of endless spreadsheets and one-way, data deprived reporting processes. The main problem is the high volume of low quality, unvalidated data; distributed through various channels, their value is not unfolded, and they are perceived as an additional responsibility, instead of a valuable tool in the hands of O&Ms, Asset Managers and local councils.
