PR Newswire

VANCOUVER, Jan. 28, 2013


VANCOUVER, Jan. 28, 2013 /PRNewswire/ - Alterra Power Corp. (TSX: AXY) is
pleased to provide the following interim period update prior to its year-end
financial reporting, which is expected in late March:

Operations: Alterra's renewable energy output for 2012 was 98% of plan
(individual plant details will be reported in March).

Montrose Hydro Facility: The Montrose facility is currently shut for penstock
repairs following the December 12 rockslide. Replacement pipe for the 300
meter damaged section has been ordered, and preparations for the repair
continue. The company expects the facility to return to full operations this
summer. The project's insurers have confirmed that the incident is covered by
property and business interruption insurance, and total insurance deductibles
related to the rockslide are expected to be less than $1 million for the
project, which is 40%-owned by Alterra.

Upper Toba Hydro: Alterra is actively working with a construction contractor
to finalize the facility's design and construction costs. Discussions
regarding project lenders and partnership arrangements are in progress.
Project construction is planned to commence in 2Q 2013.

Drilling at Reykjanes Geothermal Field: The first well in a two-well drilling
program has been completed at the Reykjanes field. Initial indications for the
completed production well are positive, and further details will follow.
Drilling for the second well will commence shortly. The expected cost for the
two-well program is $9 million, which will be paid from cash reserves at HS
Orka. The new capacity expected to result from the drilling will be used for
the planned 80 MW expansion and as reserve capacity for the existing 100 MW

Chile / Peru Partnership: Alterra and Energy Development Corporation (EDC) are
actively documenting the next-phase agreement toward full partnership, while
EDC continues to conduct its due diligence in parallel. Management expects any
final arrangements to be completed within the first half of 2013.

Possible HS Orka Transaction: Alterra continues to discuss the sale of HS Orka
with prospective purchasers. Discussions have been complicated by foreign
exchange matters and required approvals from the Central Bank of Iceland.

2013 Operating Plan: Alterra expects a solid year of on-budget performance
from its six operating plants in 2013, other than the repair time required at
the Montrose hydro facility. Further, the company has been focused on
improving its cost structure in 2013, and has made the following changes:

  *A reduction in development expenses for certain longer-term development
    projects, resulting in annual savings of approximately $1 million.
  *Streamlining of global overhead, including staffing levels, which is
    substantially completed and expected to result in further direct and
    indirect annual savings of over $2 million.
  *Potential disposition of certain small, non-core development assets which
    no longer fit Alterra's long term goals.

Further updates on these matters will be provided as part of Alterra's
year-end financial reporting.
