We may, if necessary, distribute test equipment to ICPs that have entered into the rent test sample extension agreement for contestability. The rental of this equipment is subject to the terms of the EoC agreement « Test Prod Hire ». Aside from the large small components of the renewable energy system, you`ll need to purchase additional equipment (called « system balance ») to safely transfer electricity to your consumers and meet your utility`s grid connection requirements. You may need the following: Details of the major network connections are agreed in a separate connection agreement that sets out ownership and obligation limits as well as connection fees. A prerequisite for signing a monitoring contract is that the land use plan required for the project (or the decision on planning needs) is legally valid, the connection solution meets the technical requirements and an application for an expropriation permit required for the transmission line has been submitted to the authority. Fingrid`s general interconnection conditions and specifications for the operating capacity of the power generation modules are part of the connection agreement signed with the customer. The maximum permissible rated current of a transformer without mechanical ventilation (ONAN) is 25 MVA. By equipping the transformer in question with mechanical ventilation (ONAF), the transformer can be loaded up to 30 MW. A maximum of two transformers can be switched to a single connection point, provided that the low-voltage networks between the two transformers are not connected in parallel.
The function of system operator may belong to the transmission system company or be completely independent.  They are often the total or partial property of state or national governments. In many cases, they are independent of electricity generation companies (upstream) and electricity distribution companies (downstream). They are financed either by states or countries or by charging a toll proportional to the energy they carry. The choice of the connection solution and location is made taking into account the different connection options, taking into account the security of the main network, transmission capacity, electrical safety and environmental aspects, as well as the total cost. If a new connection causes changes in the main network, this should be taken into account when planning the client project. The parties are responsible for the planning costs of their respective networks and, later, for the costs related to the construction, use and maintenance of the connection. The connection solution is agreed on a case-by-case basis. If the customer`s connection requires the construction of a new substation in the main network, the customer must pay the connection fee in the manner described in the project contract.
These components include switches to disconnect your system from the grid in the event of a power surge or power failure (so that repairers do not experience an electric shock) and power conditioning devices to ensure that your current exactly matches the voltage and frequency of the current flowing through the network. In addition, electric utilities (i.e., electric utilities) in most states allow net metering, an agreement in which excess electricity produced by grid-connected renewable energy systems « returns » your electricity meter when it is returned to the grid. If you consume more electricity in a given month than your system powers the grid, you only pay your electricity supplier the difference between what you consumed and what you produced. In Finland, geographical transmission distances mean that the main lines of the network are long and the switchgear is far away. Therefore, connections to the 110 kV transmission line are also allowed after taking into account the available transmission capacity of the transmission line and other technical circumstances. A transmission line connection refers to the connection of a branch line or substation to a transmission line on the 110 kV mainline. In addition, it is necessary that when operating in or in the immediate vicinity of fingrid`s right-of-way, a safety message is always filled in the Fingrid safety notification service. During the connection planning phase, the customer creates detailed plans for his connection and delivers them to Fingrid along with the other technical data necessary for verification. For projects where the connection requires a customer-built transmission line, planning should begin early. .
