HOUSES POWERED BY EDPR
AMOUNT OF CO2 AVOIDED
Just like oil or gas, wind energy came into prominence onshore. Later, it moved out to sea, starting in shallow water and them making steps into deeper waters.
WindFloat Atlantic Project
One of the EDPR’s most exciting projects is WindFloat Atlantic, which is the continental Europe’s first floating wind farm.
Located approximately 20 km off the coast of Viana do Castelo, where the waters reach a depth of 100 meters, WindFloat Atlantic (WFA) is under construction. It is the first next-generation offshore wind farm in continental Europe.
Structure designed to be anchored at a depth of more than 100 m.
OFFSHORE WIND FARM
First floating wind farm in continental Europe.
Capable of withstanding waves more than 17 meters high and winds of more than 60 knots.
CAPACITY OF 25MW
Total capacity of 25 MW (the consumption of approximately 60,000 households).
The facility consists of three wind turbines supported by floating platforms that integrate WindFloat technology (owned by Principle Power Inc.).
The project belongs to the Windplus consortium, which is jointly owned by OW (85.17%), Repsol (13.63%) and Principal Power Inc. (1.2%).
This project is backed by the success of the WindFloat 1 prototype. Operational between 2011 and 2016, this 2 MW prototype managed to continuously generate power for five years and withstand extreme climactic conditions without suffering any damage—including waves of up to 17 m high and winds of 60 km.
WFA has two unique features that set it apart from traditional offshore windfarms:
These two features make the involvement of large transportation and installation ships unnecessary, eliminating complex and costly operations at sea. In addition, they make it possible to set up wind turbines farther from the coast, where the seafloor is deeper and wind speeds are stronger and more regular.
Sustainable growth of renewable energy
The average lifespan of a wind turbine is 30 years. Then, wind turbines need to be assessed for safety and the future of the turbine must be determined. At this point, EDPR may consider full repowering as a solution to be accomplished. Full repowering means reducing the overall number of wind turbines and replacing them with more efficient machines which results in a net increase of power generated. Properly managing wind turbines at the end of its life from a sustainable point of view, is crucial to maximize the environmental positive impacts of wind energy from a life cycle approach.
Efficient utilization of potential wind sites producing higher amount of energy.
Modern wind turbines offer better integration with grid.
Reduced O&M costs
Reduced noise pollution
EDPR positions itself at the forefront of innovations in the renewable energy industry.
The Stocare Project
The Cobadin wind farm
In 2018, EDPR opened a battery energy storage facility at the Cobadin wind farm in the Dobrogea region of Romania. The Stocare Project, as the initiative is called, is a significant step forward in the technological development of energy storage.
Batteries are charged during days of excess wind energy production, and, when production is lower than expected, this stored energy is supplied to consumers. This reduces forecast errors from the power schedule submitted the day before, helping to minimize energy losses and cut balancing costs. The project is the first in Romania to use lithium ion batteries for electricity storage, and could lead to a breakthrough in the energy market in the coming years. By transforming renewable energies such as wind and photovoltaic solar into consistently available energy sources, these sources become even more efficient, reliable and attractive.
The Sonrisa Solar Park
In 2019, EDPR closed its first PPA with operative storage system. The Sonrisa Solar Park has secured a PPA for 200 MW of solar energy and 40 MW of energy storage, with the combination of solar and storage designed to increase efficiency and provide greater balance in energy supply. The project is located in the state of California (USA) and is expected to enter operating in 2022.
Energy storage is needed on an industrial or grid scale for three main reasons:
EDPR, as part of its R&D strategy, boosts efforts to offer sustainable energy solutions that meet customers’ increasing need to balance energy supply with grid demand.
Hybrid power plants combine various sources of power generation and energy storage to accentuate the positive aspects and address the challenges of a specific generation type, in order to produce power that is more affordable, reliable and sustainable. The combination of wind and PV offers increased capacity factor and annual generation.
By sharing the same grid connection and substation, hybrid power plants lead to savings in CAPEX and permitting times, compared to developing separate wind or solar farms. Also, the overall development and the regular O&M costs will be lower (compared to wind and solar plants located separately) given that both plants are located in a single site or in close proximity.
