1. The Department of Territory & Municipal Services (TAMS) electricity consumption expense* for the period 2005-2006 through 2008-2009 was as follows:
2005-2006: $0.423 million
2006-2007: $0.907 million
2005/06 to 2006/07 included an additional 13 sites where data was available due to centralised billing arrangements. This resulted in a doubling of the reported electricity consumption between the years.
2007-2008: $0.932 million; and
2007/08 to 2008/09 included additional sites occupied by Shared Services that were transferred to the Department. This resulted in an 11% additional consumption from the previous year.
2008-2009: $1.289 million.
Cost of GreenPower energy increased in 2008/09.
*It should be noted that for the purposes of answering this question the Department has assumed that the question relates to the consumption of electricity in buildings occupied by TAMS staff. As such, expenditure related to streetlights and other non-building related consumption has been excluded.
In addition, it should also be noted that the data provided relates to consumption expenses for properties serviced under the ACT Government’s whole of Government Electricity contract. A number of smaller sites are billed separately to the whole of government contract and as such their specific electricity consumption expenses has been excluded.
2. 9,669 tonnes.
CO2 emissions have been determined by multiplying the electricity consumption of the buildings by the CO2 emissions rate per Kilowatt Hour of electricity consumption which is 0.893 tonnes Kw.Hr -1. The carbon calculations do not include an offset for GreenPower Supply in 2008/09 due to the following factors:
• 100% GreenPower accredited renewable energy was not supplied to the ACT Government until January 2009, and this only accounts for around 7% of a 23% renewable energy supply in 2008/09.
• Prior to 1 January the ACT Government was purchasing what was termed 80/20 green energy which was a blend of old and new renewable energy sources.
3. It is estimated that TAMS’ electricity expenses for the period 2009-2010 through 2012-2013 will be as follows:
2009-2010: $1.321 million
2010-2011: $1.354 million
2011-2012: $1.388 million; and
2012-2013: $1.422 million.
It should be noted that these prices are indicative only and are based on the best quantifiable data available indexed annually by CPI.
