Its latest annual numbers demonstrated the progress.
Revenues jumped to £19.7mln (£1.3mln for 15 months), while the AIM-listed group also posted a profit of £930,000 (£7.7mln loss).
Richard Burrell, chief executive, said acquisitions over the past year had driven the improvement and will give sales a further kicker in the current year.
"The acquisition of three fuels businesses, which will see further turnover growth next year reflecting a full year's trading, has made for a transformational year at AMP.”
Most of the profits this time came from the boiler installation scheme financed by its projects business, which chipped in £1.64mln, while wood fuels contributed £367,000.
Assets under management grew to £66m comprising operational boilers, in-development peaking plant assets and other biomass assets on long term contracts.
Aggregated Micro is a case study of a vertically integrated business.
The acquisition last year of Forest Fuels made it one of the UK’s largest woodchip suppliers.
From which it supplies the biomass-fuelled boilers used by schools, care homes and business parks.
Once a boiler project is finished it is taken over by a special purpose investment vehicle AMPIL, which frees up capital to fund more new projects.
AMP provides fuel for the boilers (wood chip and wood pellets) and commissions and installs them on a long term contract.
The government's recent Renewable Heat Incentive changes through to 2021 have also helped the strategy of installing larger biomass installations with commercial heat users.
A second investment vehicle to run boiler projects installed by AMP, AMPIL2, was launched in October and this will utilise both AMP to install boilers but also buy fuel from Forest Fuels.
Peaking plant progress
AMP is also branching out into power supply and has over 80Mws of grid balancing projects with planning permission and grid connection offers. These peaking projects kick-in when demand is overwhelming the grid.
In January, it got funding (£14mln) for its first peaking plant.
Located on the Kingsnorth Industrial Estate in Kent the Ashford Power project will comprise some 21Mw of natural gas reciprocating engines, which will sell into the grid at times of peak demand.
The financing is provided by funds managed by Triple Point Investment Management.
"This is our first peaking plant project to reach financial close,” said Burrell.
“AMPH will earn project development fees, on-going operation and maintenance fees and has shares in the project which are subject to a hurdle return being achieved by Triple Point.”
Even though the company has yet to see the full impact of its wood chip and fuels fuels expansion and the peaking plant side has yet to make any real contribution, investors have started to recognise the progress being made.
Shares have risen by 50% this year to 109p, now valuing the group at £55mln.
