Contributing to the energy transition with economic profitability and the security of grid support
Integrating renewable energies into electrical installations that are already fed into the grid results in significant economic savings and environmental benefits, with the assurance that grid support is always available.
In this way, consumers use energy that they produce themselves, thus reducing consumption from the grid. This leads to savings on electricity bills and also to a reduction in emissions, as the renewable energy produced on site is cleaner than that of the energy mix. This also allows the contracted power from the grid to be reduced, which also leads to savings on the bill.
In addition to these savings by producing and consuming your own energy, you can also achieve other extra savings if you decide to compensate the surplus energy by obtaining an economic consideration for the surplus injected into the grid, or by selling the energy produced directly.
Modalities of grid-connected renewable energy
All the energy produced is injected into the grid and an economic remuneration is obtained in return.
It is a business that contributes to increasing the renewable fraction in the generation mix, i.e. it contributes to the energy transition from fossil fuels to renewable energies. In order to be able to sell to the grid, the owner of the installation must register in the producers’ register.
Installations with these characteristics are called “photovoltaic parks”. On a smaller scale, they are often referred to as “solar farms”.
All or part of the energy produced is consumed by the user to cover all or part of his energy demand.
There are different types of self-consumption, and it can also be individual or collective. In collective self-consumption, several consumers benefit from a single photovoltaic installation.
- With surplus::
-
With compensation: the excess production not consumed is injected into the grid and is compensated with energy purchased from the grid, at a more competitive price. In this way, extra savings are obtained in the electricity bill, which can even be zero.
-
Without compensation: the excess production not consumed is injected into the grid, in exchange for an economic remuneration agreed with the electricity trader.
-
-
No surplus: an anti-spill mechanism must be installed to prevent excess production from being discharged into the electricity grid. In this way, surpluses are lost.
-
A special modality, only suitable for collective self-consumption, is that of without surplus with compensation: here too, an anti-discharge mechanism is installed, but the excess production not consumed can be used by other consumers associated with the installation.
Another useful model for self-consumption is the contracting of a virtual battery. This is a system for managing surplus energy in which excess production injected into the grid at one point can be used at another point to offset the electricity bill. This is a business model that is contracted to the commercialisation companies.
How we can help you
The appropriate design of any installation has to include multiple factors: what is the economically ideal number of photovoltaic panels to install; where they are located, taking into account technical and aesthetic criteria; whether or not to incorporate battery storage; the control and monitoring system, etc.
At Intergia we study each case and, using advanced software, we offer our clients an optimal design, including cost forecasts and amortisation of the installation.
Here are the steps to follow:
- 1
Initial study: From a recent electricity bill we can determine the feasibility of installing PV and how much power. With this, we can present an initial budget estimate.
- 2
Initial visit: we carry out an initial visit to the facilities to gather the necessary information for the design of the installation and its assembly.
- 3
Installation design: our engineers design the optimal installation according to the customer’s needs and the characteristics of the location. They use specialised software for this purpose.
- 4
Assembly: once the design is ready and the final budget has been approved, the installation is assembled by our trusted fitters, ensuring maximum quality and safety.
- 5
Start-up: the last step is to “hit the ON button” and make everything work.
We also offer maintenance services, to ensure that the installation fulfils its useful lifetime to the maximum and in the best operating conditions.
