Amarenco Solar Ireland

Investment date : 2014

Joint venture with Amarenco Solar ( www.amarencosolar.com ) to develop ground mounted solar photovoltaic plants in Ireland.

Established in 2014, the company is initially developing 50 MW of consented and grid connected solar PV plants in the south of the country. Ireland is one of the only European countries not to have a solar PV industry – the UK by comparison has over 4GW of installations. In Q2 2015 Macquarie Capital took a 50% stake in the company in return for providing development and working capital.



Tidal Lagoon Swansea Bay

320 MW tidal range hydro-energy project

Status : DCO recommendation 

Investment date : 2013

This is the first of a number of innovative hydro-energy projects based on Tidal Range technology. The first, planned for Swansea bay in Wales, will have a nominal capacity of 320 MW. It will use low-head turbines to generate an annual output of c 400 GWhr. The UK has the second highest tidal range in the world after Canada and the technology potentially offers significant predictable renewable energy generation of up to 10% of the UK's requirements. The project is backed by an experienced development company with a strong track record in renewable energy  & offers significant community gain and local employment opportunities.

Government have indicated support for the project , provided a clear pathway to cost reduction can be demonstrated for further projects to be built at scale. It is an attractive option as these could be built out rapidly, allowing the country to further diversify it's renewables mix. Other marine-based renewables such as tidal stream & wave are at least a decade behind.

As of Q1 2015 a recommendation has been submitted by the UK's National Infrastructure Planning authority and the project is expected to receive a development consent order ( DCO )  in Q2. Seperately the company is engaged in detailed negotiations with the DECC on a strike price.
