Next Energy added that currently it has 763 MWp total capacity installed across 91 operating solar assets with all budgeted generation hedged for the financial year to March 2021 and 83% for the year to March 2022.
Kevin Lyon, NextEnergy Solar Fund Chairman, said: “I am pleased that, following what has been an extremely challenging period for all, NESF can present an increase in NAV.
“NESF entered the final quarter of this financial year in a very strong position, having secured attractive prices for the totality of expected generation this current financial year, plus a significant portion of expected generation for 2021/22.
Michael Bonte-Friedheim, chief executive, added: “The successful active management of NESF’s assets in the year was clear as the group enjoyed above-budget electricity generation, good asset management alpha from our portfolio management, and a significant cash benefit from our power price contract fixes.
“Progress towards our subsidy-free goal of 150 MWp is on track as NESF continues to lead the market in a transition to a subsidy-free model in the UK and beyond.”
