Macquarie Power & Infrastructure Income Fund Announces Solid First Quarter Results

  • Portfolio performing in line with expectations
  • Stable, conservative financial position
  • Strong capacity for continuing growth

TORONTO, ONTARIO (May 6, 2008) – Macquarie Power & Infrastructure Income Fund (TSX: MPT.UN; MPT. DB – “MPT” or the “Fund”), which invests in essential infrastructure assets in North America, today reported results for the first quarter ended March 31, 2008. The Fund’s Management’s Discussion and Analysis and unaudited financial statements are available on the Fund’s website at www.macquarie.com/mpt and on SEDAR at www.sedar.com.

“Overall, the Fund’s portfolio performed strongly during the quarter in line with expectations,” said Mr. Gregory Smith, President and Chief Executive Officer of the Fund. “The Fund benefited from increased power production and higher power rates as well as predictable results from Leisureworld, where the newly acquired long-term care homes made a positive contribution. Also during the quarter, the Fund increased distributions to unitholders to $1.05 per unit on an annualized basis, which represents a compound annual growth rate in distributions of 2.8% since inception.”

Financial Performance
Revenue for the quarter was $43.7 million compared with $29.0 million in the first quarter of 2007. The increase reflected the contribution from the wind, hydro and biomass power assets that the Fund acquired as part of the successful unit exchange takeover of Clean Power Income Fund (“CPIF”) on June 27, 2007 and higher power prices attributable to the continuing impact of electricity rate increases under the Cardinal facility’s (“Cardinal”) Power Purchase Agreement (“PPA”).

Income from operations1 for the Fund was $10.7 million for the quarter compared with $7.6 million for the same period last year, reflecting the higher revenue. The increase in revenue was partially offset by a $5.6-million increase in operating costs, which was due to the addition of the new assets to the portfolio as well as increased fuel usage and higher gas transportation costs at Cardinal. The growth in revenue was also offset by a $1.7-million increase in administrative expenses, which included additional management fees and cost reimbursement associated with the acquisition of CPIF as well as ongoing business development activities. The Fund’s distributable cash2 was $16.5 million ($0.330 per unit) compared with $12.1 million ($0.402 per unit) in 2007. Declared distributions to unitholders for the quarter were $13.1 million ($0.262 per unit) compared with $7.7 million ($0.257 per unit) in 2007, representing a payout ratio of 80% (Q1 2007 – 64%). The higher payout ratio reflects the cash flow from the newly acquired assets, which was offset by higher distributions declared to unitholders. The increase in distributions declared was due to a greater number of units outstanding as a result of the issuance of units in connection with the acquisition of CPIF as well as an increase in distributions to unitholders of $0.02 per unit on an annualized basis. Distributions to unitholders are paid from cash flows from operations and unrestricted cash balances.

Financial Position
As at March 31, 2008, the Fund had positive working capital of $32.7 million and cash on hand of $25.6 million, including fully funded general, major maintenance and capital expenditure reserve accounts in the aggregate amount of $18.9 million. The Fund is conservatively leveraged, with a debt to capitalization ratio of 39.3%.

Operational Performance
Total power production for the quarter increased 65% to 568,838 MWh compared with 344,543 MWh last year.

Cardinal performed in line with expectations, producing 346,244 MWh of electricity (Q1 2007 – 344,543 MWh), which reflected fewer outages in 2008 compared with 2007. As a result, Cardinal achieved availability of 99.9% (Q1 2007 – 99.2%) and capacity of 98.5% (Q1 2007 – 97.9%). Subsequent to quarter end, Cardinal completed its combustion inspection in four days instead of the five days typically required.

Production at Erie Shores Wind Farm (“Erie Shores”) totalled 81,933 MWh (Q1 2007 – 88,686 MWh), which was in line with the Fund’s forecast. The wind speed and density in the quarter was less than the unusually strong conditions experienced in the first quarter of 2007. The facility achieved an overall availability of 97.4% (Q1 2007 – 95.9%) and a capacity factor of 38.1% (Q1 2007 – 40.8%).

The Fund’s hydro power facilities delivered production of 29,937 MWh in line with the same period last year (Q1 2007 – 30,091 MWh). The two hydro facilities in Ontario experienced increased water flows. This was offset by colder than usual conditions at the Sechelt facility in British Columbia, which resulted in decreased water flows, and planned electrical and mechanical maintenance at the facility during the quarter. Overall, the hydro power facilities had a weighted average availability of 92.9% (Q1 2007 – 98.5%) for the quarter and a capacity factor of 38.6% (Q1 2007 – 39.0%).

The Whitecourt biomass plant (“Whitecourt”) operated at 100% availability (Q1 2007 – 93.4%) as there were no outages during the quarter compared with two outages in the same quarter last year. The facility achieved a capacity factor of 98.7% (Q1 2007 – 92.7%). Total production at Whitecourt was 52,109 MWh (Q1 2007 – 46,760 MWh).

The Chapais facility (“Chapais”), in which the Fund holds a minority preferred equity and debt interest, experienced availability of 96.6% (Q1 2007 – 99.9%). Production at Chapais for the quarter was 58,615 MWh (Q1 2007 – 60,186 MWh).

The Fund owns an indirect 45% equity interest in Leisureworld Senior Care LP (“Leisureworld”), which is accounted for by the Fund as an equity investment. On January 31, 2008, Leisureworld completed the acquisition of seven long-term care homes, making it the third largest provider of long-term care in the province of Ontario. This transaction is expected to contribute to the sustainability and predictability of Leisureworld’s distributions to the Fund.

During the quarter, Leisureworld achieved a 27.1% increase in revenue and an 8.1% increase in income from operations, reflecting the contribution of the new homes, improved occupancy and greater use of private accommodation across its portfolio, and increased government funding. Average total occupancy for the quarter was 98.1% (Q1 2007 – 97.5%). The average occupancy of private rooms was 91.9% (Q1 2007 – 87.8%).

Outlook
“Our portfolio continues to deliver stable performance, which reflects the essential nature, inelastic demand and predictable cash flow of critical infrastructure assets,” said Mr. Smith. “In addition, we continue to have substantial financial capacity for growth, including up to $100 million under our credit facilities. Our goal is to build a significant, diversified portfolio of infrastructure assets that returns exceptional long-term value to unitholders.”

In 2008, Cardinal will continue to benefit from higher electricity rates under its PPA. This will be offset by higher than anticipated gas transportation costs, reflecting the impact of a regulated rate increase to $1.31/GJ from $1.09/GJ that was awarded to TransCanada Pipelines Limited, which transports gas to the Cardinal facility, effective April 1, 2008. Erie Shores is performing in line with the Fund’s forecast and is expected to deliver annual production of approximately 245,600 MWh, subject to wind speed and density, which are typically greatest during the fall and winter months. Warranted plant availability of 97% is guaranteed by GE, the turbine supplier, including direct revenue reimbursement if that threshold is not met. Erie Shores’ annual maintenance, which typically requires approximately four to five days of outage, is expected to be completed during the seasonally low third quarter.

Strong performance from the hydro facilities is expected through the spring months as weather conditions warm. Water flows are typically strongest during the spring and fall months. The impact of fluctuating water flows on revenue is mitigated by the geographic diversification of the hydro assets across the Arctic, Atlantic and Pacific watersheds. Additionally, the PPAs at Wawatay and Dryden provide for higher electricity rates during the months of October to March.

The hydro facilities are expected to generate long-term average production of 166,360 MWh per year, which represents average actual historical production at each of the plants. This long-term average includes the impact of outages required for mechanical and electrical inspections at the plants, which are typically scheduled for seasonally low periods. Whitecourt continues to operate reliably, reflecting the stability of its fuel supply and strong maintenance program. The plant operates on a seven-year maintenance cycle and will undergo major maintenance in May 2008, which is expected to require an approximately 24- day outage. Importantly, routine major maintenance costs at each of the Fund’s power plants are fully funded through the Fund’s major maintenance reserve account and have no impact on distributable cash.

At Leisureworld, a key focus in 2008 is on securing approval from the Ontario Ministry of Health and Long-Term Care for the acquisition of the Good Samaritan Seniors Complex. Leisureworld is continuing its emphasis on optimizing occupancy across its homes and on increasing the number of residents choosing private accommodation, which contributes to Leisureworld’s operating profitability. Leisureworld has a significant critical mass in the Ontario long-term care sector and is well positioned to capitalize on complementary acquisition opportunities that will further enhance the stability and quality of the portfolio.

For 2008, the Fund anticipates achieving a payout ratio of approximately 100%, which reflects the impact of higher operating expenses at Cardinal primarily due to the greater than expected increase in gas transportation costs.
