Hand in hand with the advancement of technology related to photovoltaic panels and batteries for home storage, The methods of selling/purchasing energy generated by individuals by the companies that manage the grid are also evolving.
For example, in the United States, on-site metering (SSP) is used, in which the electricity generated by a photovoltaic system is fed into the national power grid. is about to give way to virtual power plants (VPPs). capable “exploit” also domestic storage.
Although it may seem counterintuitive at first glance, The proliferation of batteries will help the grid to manage energy supply and demand flows much better than on-site metering: Unlike the SSP, the batteries actually only allow the release of energy If and when There is a real need for this.
This is how you avoid too Overload power linesto avoid the risk of damage and power outages: The alarm associated with the “Excess” As reported by , the European Union has also launched electricity generation from renewable energy sources (EES). El Pais.
“Home solar systems and batteries can play an essential role in keeping the grid functioning and keeping electricity costs down for everyone.”said Aaron Nitzkin, executive vice president of solar energy at Citadel Roofing and Solar, a California-based company specializing in the sales, installation and service of photovoltaic, solar and storage systems.
To understand how this new energy storage and transmission system works “upon request” Let’s take what the newspaper reports pvmagazinewhich cites as an example the Californian company Pacific Gas & Electric, which has started a program “Reducing energy requirements in times of emergency”.
Customers who register their batteries You can earn $2 per kWh stored by PG&Ebecause they relieve the power grid when demand is very high: In practice The more energetically independent a customer becomes, the more money their manager makes.
According to pvmagazine, this initiative would mean that each photovoltaic and storage owner can earn between 2.0 and 2.5 million euros $100 and $250 annually. However, this earning opportunity will not be available all year round only in times when demand is very high: Specifically, PG&E has established seasonal events lasting 20 to 60 hours Anyone who does not request energy from the network receives money from the manager.
However, Long Island, New York-based provider PSEG took a different approach: offers a discount on the price of one of the batteries included in its program when purchasing Battery storage rewards.
Installers can suggest their products reduced by $250 per kWh, resulting in a maximum of $6,250 less for each customer: In return for a reduction in the purchase price, the owners of the storage system receive They must allow PSEG to draw some energy from their batteries during times of peak electricity demandmaximum 10 times a year.
“Grid service programs provide value to battery-powered homeowners by expanding access to this important technology.”said Michael Catizone, president and co-founder of Long Island Power Solutions, a leading solar installation company in New York. “With increasing electrification and demand on the grid, we are excited to expand initiatives like this.”.
These are not the only initiatives for the future of our energy availability, which must also take into account the batteries of electric cars and, to some extent, storage systems on wheels.
The UK, for example, has recently funded some interesting projects the implementation of V2G technologyVehicle to Grid.
