Overview

Capstone Infrastructure Corporation was a Canadian infrastructure investment business based in Toronto, Ontario. The organization was formerly known as Macquarie Power & Infrastructure Income Fund, or MP&I, and earlier operated under the name Macquarie Power Income Fund. Its business model centered on owning or investing in infrastructure assets that could generate relatively stable operating and contracted cash flows, with power generation becoming the principal focus. The fund entered the public market in April 2004, when it listed on the Toronto Stock Exchange as Macquarie Power Income Fund. At that time, its portfolio consisted of a single major asset: the 156-megawatt Cardinal natural-gas-fired power plant. In April 2005, founding President and Chief Executive Officer Bob Rollison described a broader acquisition strategy. The stated mandate extended beyond electricity generation into other infrastructure categories, reflecting the income-fund model then used by several Canadian publicly traded vehicles. That broader mandate led to the acquisition of a 45 percent interest in Leisureworld in 2005. Leisureworld operated long-term-care facilities in Ontario, making the investment materially different from MP&I's power assets. Management subsequently divested the holding in 2009. The disposal was presented as a strategic effort to concentrate the portfolio on infrastructure categories regarded as more central to the business, including power generation, electricity transmission and distribution, utilities, and transportation. A major expansion occurred in June 2007, when MP&I completed the purchase of Clean Power Income Fund. The transaction approximately doubled the scale of the asset base and marked MP&I's entry into renewable energy. Through the acquisition, the organization obtained an ownership interest in the Erie Shores wind farm, four hydroelectric projects—Sechelt, Hluey Lakes, Wawatay and Dryden—the Whitecourt biomass facility, and a 31.3 percent interest in the Chapais biomass plant. The portfolio therefore combined conventional thermal generation with wind, hydroelectric and biomass assets. Regional Power, a subsidiary of Manulife Financial, was identified as overseeing day-to-day operations at four of MP&I's hydro facilities: Sechelt, Hluey Lakes, Dryden and Wawatay. This arrangement illustrates the distinction between the investment vehicle's ownership role and the operational management of individual facilities. The organization also pursued solar development. It developed a planned 20-megawatt solar park in Amherstburg, Ontario. SunPower was contracted to design, build and operate the facility, and the project received a 30-year power-purchase agreement from the Ontario Power Authority. The planned solar project represented an extension of the portfolio into utility-scale solar generation and a further move toward a diversified renewable-energy mix. The Capstone Infrastructure name is associated with the organization's evolution from a single-asset, publicly listed power-income fund into a broader infrastructure platform with conventional and renewable generation holdings. The available reference material does not establish the organization's later ownership, operating status, executive roster, website, or definitive corporate end state; those fields therefore remain unconfirmed.

History

Capstone Infrastructure's documented history begins with its earlier identity as Macquarie Power Income Fund. The fund listed on the Toronto Stock Exchange in April 2004. Its initial portfolio was concentrated in one asset, the 156-megawatt Cardinal natural-gas plant, giving the newly public vehicle a straightforward power-generation profile. In April 2005, founding President and CEO Bob Rollison outlined a broader acquisition strategy. The fund sought to expand beyond electricity generation and consider infrastructure assets in other sectors. This strategy led to the purchase of a 45 percent interest in Leisureworld later in 2005. Leisureworld operated long-term-care facilities in Ontario, and the investment demonstrated the breadth of the fund's initial infrastructure mandate. The cross-sector strategy was later narrowed. In 2009, management divested the Leisureworld investment and stated that it intended to concentrate on infrastructure categories considered core to the organization. These included power generation, electricity transmission and distribution, utilities and transportation. The divestiture was therefore both an asset sale and a portfolio-repositioning decision. The most important expansion in the available history took place in June 2007, when Macquarie Power & Infrastructure Income Fund completed its purchase of Clean Power Income Fund. The transaction approximately doubled the organization's assets and brought it into renewable energy. The acquired portfolio included the Erie Shores wind farm, four hydro projects—Sechelt, Hluey Lakes, Wawatay and Dryden—the Whitecourt biomass plant, and a 31.3 percent interest in the Chapais biomass plant. These assets diversified the organization across wind, hydroelectric and biomass generation while retaining its exposure to power infrastructure. Operational responsibilities were not necessarily performed directly by the investment fund. Regional Power, described as a subsidiary of Manulife Financial, oversaw daily operations at the Sechelt, Hluey Lakes, Dryden and Wawatay hydro facilities. This operating relationship formed part of the asset-management structure supporting the portfolio. The company also pursued utility-scale solar development in Ontario. It worked on a 20-megawatt solar park in Amherstburg, with SunPower contracted to design, build and operate the facility. The project was awarded a 30-year power-purchase agreement by the Ontario Power Authority, providing a long-duration contractual framework for the planned generation. Across these stages, the organization evolved from a single-asset power-income fund into a diversified Canadian infrastructure platform. Its documented portfolio combined natural-gas generation with wind, hydro, biomass and planned solar assets. The available sources do not provide sufficient information to confirm the exact date of the Capstone Infrastructure rebranding, its subsequent ownership, current operations, or final corporate status.
