Macquarie Power & Infrastructure Income Fund Announces Increased Cash Distribution And Second Quarter 2006 Results

TORONTO, August 9, 2006 – Macquarie Power & Infrastructure Income Fund (TSX: MPT.UN – “MPT”, the “Fund”) today announced results for the second quarter ended June 30, 2006.

The Fund also announced a 3% increase to its monthly cash distributions from $0.08333 to $0.08583 per unit, the equivalent of $1.03 per unit on an annualized basis. The distribution increase will apply commencing with the August 2006 distribution payable in September 2006.

Fund Results for the Second Quarter ended June 30, 2006
The Fund generated revenue for the quarter of $16.3 million, a 17.3% decrease on revenue from the previous corresponding quarter of $19.7 million. The decrease in revenue versus the period in 2005 was due largely to the scheduled major maintenance of the Cardinal plant which happens every six years. Loss from operations1 for the Fund was $1.3 million for the quarter, compared to income of $1.9 million for the previous corresponding quarter. The Fund’s distributable cash2 for the quarter was $6.3 million ($0.210 per fully diluted unit), compared to the previous corresponding quarter of $4.3 million ($0.202 per fully diluted unit).

Declared distributions to unitholders for the quarter were $7.5 million ($0.250 per unit), representing a payout ratio of 119% (Q2 2005 – 113%).

The increase in the Fund’s distributable cash and distributable cash per unit for the quarter reflected distributions of $2.6 million from Leisureworld as well as the continuing impact of electricity rate increases under Cardinal’s Power Purchase Agreement with Ontario Electricity Financial Corporation and decreased fuel transportation costs for the quarter.

The improvement in the Fund’s distributable cash for the quarter was partially offset by the major maintenance outage during the quarter. The major maintenance program occurs every six years and required the facility to be shut down for 22 days during the quarter. Also impacting the change in distributable cash is the accrual of the Fund’s administration expenses on a quarterly basis to better align revenues and costs going forward. Prior to 2006, these costs were primarily recorded in the fourth quarter.

=====================================================

1 Income from operations is net income less unrealized gains or losses, interest and equity accounted income or loss.

2 Distributable cash is cash flows from operating activities after removing changes in working capital and reflecting the impacts of releases from maintenance reserves, allocations to major maintenance and capital expenditure reserves and distributions from Leisureworld.

As at June 30, 2006, the Fund had cash and cash equivalents totalling $18.0 million, of which $5.1 million was allocated to its general, major maintenance and capital expenditure reserve accounts. The balance of this amount is maintained as free cash on hand and is available to finance the seasonality of operations and investment opportunities.

Mr. Gregory Smith, Chief Executive Officer of the Fund, said, “The Fund has continued its solid performance for the year, with the second quarter displaying growing cash flows and strong operating performances generated from the underlying Cardinal and Leisureworld businesses. “We are pleased to report the completion of Cardinal’s major maintenance program. The program was completed ahead of schedule with costs fully funded from our major maintenance reserve. Each of Leisureworld’s most recently opened facilities have also demonstrated consistent growth in occupancy levels, with the new Orillia facility on track to be opened in the fourth quarter.”

Cardinal Operational Performance
During the quarter the Cardinal plant had availability of 77.4% (Q2 2005 – 95.6%), capacity of 75.0% (Q2 2005 – 94.1%) and electricity sales of 243,000 MWh (Q2 2005 – 306 MWh). The change, when compared with the prior corresponding period, was due to the scheduled major maintenance of the Cardinal plant.

Leisureworld Operational Performance
Through its 45% indirect interest in Leisureworld Senior Care LP (“LSCLP”), the Fund owns a 45% interest in Leisureworld which it accounts for as an equity investment.

During the quarter, Leisureworld continued to operate in line with expectations, demonstrating steady growth in revenue. Of Leisureworld’s 19 facilities, 17 LTC facilities are considered mature and have average total occupancy of 98% for the six months ended June 30, 2006 (2005 – 90.8%). One facility, Vaughan, is still in ramp up and recorded average total occupancy of 66.0% for the six months ended June 30, 2006 (2005 – 29.6%). The remaining facility, Spencer House, is in the process of being closed and replaced by a new facility in Orillia, scheduled to open in the fourth quarter of 2006. Average total occupancy at the Spencer House facility for the six months ended June 30, 2006 was 84.5% (2005 – 93.3%).

Preferred bed average total occupancy for the same mature facilities is 81.6% for the six months ended June 30, 2006 (2005 – 77.5%).

Increase in Monthly Distributions
The Fund’s Board of Trustees has approved an increase in the Fund’s monthly cash distributions from $0.08333 to $0.08583 per unit. The distribution increase will apply commencing with the August 2006 distribution payable in September 2006.

“The increase in the Fund’s cash distributions per unit continues our commitment to profitably grow the Fund and deliver sustainable distributions to unitholders over time,” said Mr Smith.

“The decision to raise the monthly distribution amount to unitholders is underpinned by the stable and growing cash flows generated by both Cardinal and Leisureworld businesses. The Board of Trustees also continues to anticipate maintaining an annual payout ratio of less than 95% for 2006.

Management anticipates that in excess of 75% of distributions for 2006 will reflect a return of capital, based on current operations and barring any significant external shocks.

Non-GAAP Financial Measures
"Income from operations" and "distributable cash" do not have any standardized meaning under Canadian Generally Accepted Accounting Principles (GAAP). Management believes they are useful measures of performance as they provide investors with indications of income from operations and the amount of cash available for distribution to unitholders. The Fund's method of calculating "income from operations" and "distributable cash" may not be comparable to other similarly named calculations.
