Connections Reform is a project being run by the Electricity System Operator (ESO) to change the way connection application to the transmission system are handled. Here we provide some quick fire answers to a few key questions.
Constraints are present in many electricity network connections. This article explains what constraints are, how they can impact grid connections and how they are different from curtailment.
Grid offers come with a long list of caveats that over the course of the development process need to be worked through and clarified to avoid pitfalls and delays. Here, we highlight common elements of the post-acceptance process that can catch some developers out.
The terms firm and non-firm are used in relation to grid connections in various ways. The two main ways are in relation to the connection design and network access, as we explain here.
The Embedded Capacity Register (ECR) is a list of energy generation projects (1MW or bigger) connected or contracted-to-connect to the electricity distribution networks (embedded).
A high quality G99 application is crucial. If the application is flawed, the scheme can carry risks that may not get picked up on until close to, or after, energisation. These risks range from being detrimental – whereby connection timeframes or ongoing uptime are compromised – to catastrophic.
We help explain the difference between transmission and distribution connections, and the timescales you can expect with transmission connections.
We help explain how transformers work, and illustrate primary and secondary windings.
We explain the difference between power and energy - and the terms megawatt (MW), kilowatt (kW) and megawatt (MWh) and kilowatt hour (kWh)
We help explain transmission and distribution networks in a simple way for those who are new to renewable energy projects.
