Eligible Renewable/Other Technologies:
Note: The Tax Cuts and Jobs Act of 2017 repealed section 54C of the Internal Revenue Code, which authorized the use of New CREBs. IRS Notice 2018-15 announced that the IRS will no longer process applications for or issue allocations of New CREBs. The summary below describes CREBs before they were repealed, and is here for historical purposes only.
Clean renewable energy bonds (CREBs) may be used by certain entities -- primarily in the public sector -- to finance renewable energy projects. The list of qualifying technologies is generally the same as that used for the federal renewable energy production tax credit (PTC). CREBs may be issued by electric cooperatives, government entities (states, cities, counties, territories, Indian tribal governments or any political subdivision thereof), and by certain lenders. The bondholder receives federal tax credits in lieu of a portion of the traditional bond interest, resulting in a lower effective interest rate for the borrower.* The issuer remains responsible for repaying the principal on the bond.
The Energy Improvement and Extension Act of 2008 (Div. A, Sec. 107) allocated $800 million for new Clean Renewable Energy Bonds (CREBs). In February 2009, the American Recovery and Reinvestment Act of 2009 (Div. B, Sec. 1111) allocated an additional $1.6 billion for New CREBs, for a total New CREB allocation of $2.4 billion. The Energy Improvement and Extension Act of 2008 also extended the deadline for previously reserved allocations ("Old CREBs") until December 31, 2009, and addressed several provisions in the existing law that previously limited the usefulness of the program for some projects. A separate section of the law extended CREBs eligibility to marine energy and hydrokinetic power projects.
Participation in the program is limited by the volume of bonds allocated by Congress for the program. Participants must first apply to the Internal Revenue Service (IRS) for a CREBs allocation, and then issue the bonds within a specified time period. The New CREBs allocation totaling $2.4 billion does not have a defined expiration date under the law; however, recent IRS solicitations for new applications require the bonds to be issued within 3 years after the applicant receives notification of an approved allocation (see History section below for information on previous allocations). Public power providers, governmental bodies, and electric cooperatives are each reserved an equal share (33.3%) of the New CREBs allocation. IRS Notice 2015-12, however, divided the remaining volume cap differently: $516,565,691.35 for public power providers, $597,134,963.60 for governmental bodies, and $280,778,469.00 for cooperative utilities.
The tax credit rate is set daily by the U.S. Treasury Department. Under past allocations, the credit could be taken quarterly on a dollar-for-dollar basis to offset the tax liability of the bondholder. However, under the new CREBs allocation, the credit has been reduced to 70% of what it would have been otherwise. Other important changes are described in IRS Notice 2009-33.
CREBs differ from traditional tax-exempt bonds in that the tax credits issued through CREBs are treated as taxable income for the bondholder. The tax credit may be taken each year the bondholder has a tax liability as long as the credit amount does not exceed the limits established by the federal Energy Policy Act of 2005. Treasury rates for prior CREB allocations, or "Old" CREBs are available here, while rates for New CREBs and other qualified tax credit bonds are available here.
In April 2009, the IRS issued Notice 2009-33, which solicited applications for the New CREB allocation and provided interim guidance on certain program rules and changes from prior CREB allocations. The expiration date for New CREB applications under this solicitation was August 4, 2009. Further guidance on CREBs is available in IRS Notices 2006-7 and 2007-26 to the extent that the program rules were not modified by 2008 and 2009 legislation. In October 2009, the Department of Treasury announced the allocation of $2.2 billion in new CREBs for 805 projects across the country. A new solicitation (IRS Announcement 2010-54) was issued in September 2010 for roughly $191 million in unallocated New CREB bond volume available only to electric cooperatives. The award announcement for this allocation was made in March 2011. It remains to be seen if or when the IRS will issue new funding announcements for Old CREB allocations which were not issued by the December 31, 2009 deadline, or New CREB allocations which miss the three-year issuance period.
The federal Energy Policy Act of 2005 (EPAct 2005) established Clean Energy Renewable Bonds (CREBs) as a financing mechanism for public sector renewable energy projects. This legislation originally allocated $800 million of tax credit bonds to be issued between January 1, 2006, and December 31, 2007. Following the enactment of the federal Tax Relief and Health Care Act of 2006, the IRS made an additional $400 million in CREBs financing available for 2008 through Notice 2007-26.
In November 2006, the IRS announced that the original $800 million allocation had been reserved for a total of 610 projects. The additional $400 million (plus surrendered volume from the previous allocation) was allocated to 312 projects in February 2008. Of the $1.2 billion total of tax-credit bond volume cap allocated to fund renewable-energy projects, state and local government borrowers were limited to $750 million of the volume cap, with the rest reserved for qualified municipal or cooperative electric companies.

*In March 2010 Congress enacted H.R. 2847 (Sec. 301) permitting New CREB issuers to make an irrevocable election to receive a direct payment -- a refundable tax credit -- from the Department of Treasury equivalent to and in lieu of the amount of the non-refundable tax credit which would otherwise be provided to the bondholder. This option only applies to New CREBs issued after the March 18, 2010 enactment of the law. In April 2010 the IRS issued Notice 2010-35 providing guidance on the direct payment option.
