Grid connection is one of the greatest challenges for renewable energy and novel demand projects in the UK. Large areas of the UK distribution network are now saturated with Distributed Generation, and some Distribution Network Operators (DNOs) are now struggling to connect all types and levels of generation, without charging significant amounts for both the quotation and connection works. Decerna has a well-respected reputation for providing independent advice on a range of renewable and grid related topics, having worked with large multi-nationals, local authorities, SMEs and district councils, amongst others.
Technical support and negotiations
Decerna grid work is led by two former DNO design engineers who work closely with Distribution Network Operators throughout England, Scotland & Wales to ensure that our clients get the best possible grid connection for their renewable energy/storage systems. Specialities include connecting solar farms, wind farms and grid scale batteries to the grid.
In order to reduce both time and expense for our clients we offer a site finding service, in which we search specific regions to find potential points of connection for new renewable energy/storage installations. Should you already have a site in mind we can make an EREC G99 application on your behalf, in accordance with ENA (Energy Network Association) guidance, to the relevant DNO or Transmission Network operator. Alternatively, we can provide ‘Stop – Go assessments’ for all types of demand and generation projects. We can also negotiate the best option for both the client and the Distribution Network Operator, considering all financial and technical options. Additionally, we offer EREC G99 training, as well as familiarisation workshops to aid understanding of the UK electricity network.
Besides locating points of connection, we can calculate the yield and predict the output of your photovoltaic (PV) system, advise on multiple types of energy storage systems and explain the plethora of incomes available, such as PPAs and sleeving arrangements, and if you prefer. We can speak with providers on your behalf and identify the economic development opportunities available for you.
If required, we can take a site through to the point of being spade ready, with G99 applications and planning approval, and facilitate the procurement process for ICPs and other contractors. We can also act as an owners engineer to monitor site works, and act as an on call consultant.
In addition to identifying points of connection for generation, we can also locate areas with strong networks, capable of supporting the high demand required for new infrastructure, such as electric vehicle charging stations.
We also consult on new technologies to ease grid connection, including smart grid technologies and energy storage. We can advise on new off-the-shelf technologies, and work with our partners on R&D for new grid technologies.
We can assist in locating the most suitable ICP (Independent Connection Provider) or IDNO (Independent Distribution Network Operator) to carry out the contestable element of your connection or we can offer a ‘turnkey’ service whereby we will arrange to have your connection carried out in full with minimal input from the customer.
Policy and advice
We ensure that as a company, NDE is fully up to date with all relevant policy, legislation and engineering recommendations in terms of utility scale renewables and energy storage systems. This includes a watching brief on the developments for COP26, the constant updates of EREC G99, planning regulations, Ofgem rules, grid balancing services, and the ever changing planning policy framework across England, Scotland and Wales.
