Investment company, Bluefield Solar Income Fund (BSIF) has completed the deal for its tenth large-scale solar project in the UK. The 17.5MW Hertfordshire solar power plant's acquisition cost £19 million.

Solarcentury is to construct the park and will oversee operations and maintenance (O&M). The solar park is to be considered for the 1.4 Renewable Obligation Certificate (ROC) scheme.

Bluefield Solar has invested in ten solar power plants since July last year – totalling 128MW. Nine of these solar plants used the £130 million in proceeds from BSIF's Initial Public Offering (IPO), with the ninth requiring an additional £13 million for completion.

Bluefield had acquired its second project by September 2013, completed its eight acquisition in January and ninth in February of 2014.

Five of the portfolio became live in April this year, qualifying for the higher 1.6 ROC rate in the process.

This 17.5MW solar power plant acquisition is the first Bluefield Solar investment using the Royal Bank of Scotland’s revolving credit facility, announced four days ago.

The facility is a three year flexible fund of up to £50 million; Bluefield plans to make additional acquisitions of UK solar power plants with the facility.
