The problem with tertiary connections
Tertiary connection offers come with issues. Here we explain some, including cost, constraints, timescales, ownership and third party works.
The differences between transmission and distribution connections
We help explain the difference between transmission and distribution connections, and the timescales and costs you can expect with transmission connections.
P28, the engineering recommendation limiting the deployment of battery storage
Interpretation by some DNOs of Engineering Recommendation P28 is threatening the deployment of battery storage schemes across large parts of the GB network. It has sparked an urgent debate, and one which Roadnight Taylor is proud to be influencing.
What is Category Z Active Network Management?
We explain what is Category Z Active Network Management (ANM) and what it means for some proposed grid connection projects.
What is Active Network Management?
We explain what is Active Network Management (ANM) and what it means for some proposed grid connection projects.
What limits Active Network Management systems?
Two factors limit an Active Network Management System; financial and technical limitations. This article discusses these in detail.
What is Category B Active Network Management?
We explain what is Category B Active Network Management (ANM) and what it means for some proposed grid connection projects.
What are tertiary connections?
We illustrate tertiary windings and connections, and explain why they are so popular for connections.
What is curtailment in electricity networks and how does it work?
We explain what is network curtailment, how it is calculated, and how you can seek further help to understand potential curtailment on your project.
What is demand headroom?
We explore the rating of the network for demand and the headroom for new demand connections.
What can affect the deliverability of a cable route?
We highlight some of the main challenges to installing an underground cable and delivering the cable route for an energy project
How close does an energy scheme need to be to an electricity network?
We look at how far a site can be from an EHV network, and at what point it might become unviable
What are circuit ratings?
What explain what is meant by circuit rating and the impact on developers looking to connect new demand, generation or energy storage projects
What are transformers and how do they work?
We help explain how transformers work, and illustrate primary and secondary windings.
What are second comer charges?
We explain second comer charges for distribution networks, payment of charges and the presentation of second comer charges in connection offers
Triggered or planned network reinforcement – help or a hinderance?
Reinforcements that have already been triggered on a network can be either a help or a hinderance to new connections. Here we explain more.
What is network reinforcement?
We explain what is network reinforcement, what solutions are available to network companies to enable new connections and who pays for them.
What is reverse power flow?
We explain what is reverse power flow and the issues that it can cause.
What is the difference between power and energy?
We explain the difference between power and energy - and the terms megawatt (MW), kilowatt (kW) and megawatt (MWh) and kilowatt hour (kWh)
What is network complexity?
We help explain network complexity for those who are new to networks and renewable energy projects.
What is National Grid?
'The national grid’ is commonly used to describe the entire electrical network in GB. However, from a network perspective, ‘National Grid’ is a much more specific term, which we describe in this article.
Electricity transmission and distribution networks for newbies
We help explain transmission and distribution networks in a simple way for those who are new to renewable energy projects.
