黑石集团的主打私募股权基金早就已经进行能源投资，比如最近宣布与Alta Resources成立10亿美元的合资企业，计划在北美收购和开发非传统油气资产。新基金将专注于规模略小的交易，包括一些成长型股权投资。

    团队成员将包括此前曾主管黑石集团失败的清洁技术平台的杰米•季根。季根将继续参与黑石集团综合基金的科技投资。

    关于黑石集团此次新基金募集是否已获得部分出资承诺，尚未有任何消息。新基金的募资推介可能由黑石集团下属的配售公司Park Hill Group负责。黑石集团的一位发言人拒绝置评。

    研究公司Preqin的数据显示，上个季度，4家能源私募股权基金共募资51亿美元。其中最大的是最终募资规模35亿美元的EnCap Energy Capital Fund VIII。

    Blackstone already makes energy investments out of its main private equity fund, such the recently-announced $1 billion joint venture with Alta Resources to acquire and develop unconventional oil and gas assets in North America. The new vehicle will focus on slightly-smaller transactions, including some growth equity investments.

    Team members will include Jamie Kiggen, who most recently led Blackstone's failed cleantech platform. Kiggen also will continue to work on technology investments for Blackstone's general fund.

    No word on if Blackstone has secured any commitments yet for the new effort, which likely will be marketed by in-house placement team Park Hill Group. A Blackstone spokesman declined to comment.

    According to research firm Preqin, four energy-focused private equity funds raised a total of $5.1 billion last quarter. The largest was a $3.5 billion final close for EnCap Energy Capital Fund VIII.
