Energy and climate change legislation made its way to the U.S. Senate June 26 after barely passing the House on a 219-212 vote at 2:20 a.m. The American Clean Energy & Security Act, H.R. 2454, included 309 pages of last-minute amendments--many important to California, including one that would enhance the state\u2019s authority over transmission siting. The key change on transmission reduces Federal Energy Regulatory Commission \u201cbackstop\u201d authority to order a power line sited. In Section 151 of the bill, backstop authority \u201cwould not be available unless the developer of the line filed an application for siting of the line with the relevant state authority and such state authority did not issue a decision on the application within one year, denied the application, or authorized the siting of the facility subject to conditions that unreasonably interfere with development of the facility,\u201d according to an Energy & Commerce Committee report on the changes. Other last-minute changes include: Section 132--Permits states to convey allowances in certain accounts directly to renewable energy generators. Sections 341, 342, 358--The Commodity Futures Trading Commission regulates allowance derivatives and prohibits over-the-counter trading of such derivatives. Section 246--Requires the Secretary of Commerce to start a program to award grants to states to establish revolving funds for small- and medium-sized manufacturers to both add their own efficiency measures and produce clean energy technologies. Section 790--Assuming a national cap-and-trade market, state-granted allowances must be retired.
