Tree Trimming Costs

In January 2008, the LPSC approved Cleco Power’s request to establish a regulatory asset for costs incurred to trim, cut, or remove trees that were damaged by hurricanes Katrina and Rita, but were not addressed as part of the restoration efforts. The regulatory asset was capped at $12.0 million in actual expenditures plus a 12.4% grossed-up rate of return. Recovery of these expenditures was requested in Cleco Power’s base rate application filed in July 2008 and was approved by the LPSC in October 2009. In February 2010, Cleco Power began amortizing the regulatory asset over a five-year period.

On January 29, 2013, Cleco Power requested to expend and defer up to $8.0 million in additional tree management costs. Cleco Power requested similar accounting treatment as authorized in the initial tree extraction request and requested authorization to accrue actual expenditures to a regulatory asset through the completion date of the tree extraction effort. Cleco Power anticipates a completion date of December 31, 2014 for this phase of the tree extraction project. The LPSC approved this request on April 4, 2013.

Construction Carrying Costs

In February 2006, the LPSC approved Cleco Power’s plans to build Madison Unit 3. Terms of the approval included authorization for Cleco Power to collect from customers a portion of the carrying costs of capital during the construction phase of the unit. Cleco Power’s retail rate plan established that Cleco Power return carrying costs to customers and record a regulatory asset for all carrying costs incurred by Cleco Power above the actual amount collected from customers. These costs are being amortized over a four-year period. As of March 31, 2013, Cleco Power had returned $163.1 million to customers. At March 31, 2013, $3.3 million is due to be returned to customers within one year.

Power Purchase Agreement Capacity Costs

In March 2012, Cleco Power received approval from the LPSC for a three-year power purchase agreement with Evangeline providing 730 MW of capacity and energy beginning May 1, 2012, and ending April 30, 2015. The LPSC order allows Cleco Power to defer and recover a portion of capacity costs associated with the power purchase agreement. The deferred costs are being collected over the term of the contract.

AMI Deferred Revenue Requirement

In February 2011, the LPSC approved Cleco Power’s stipulated settlement in Docket No. U-31393 allowing Cleco Power to defer, as a regulatory asset, the estimated revenue requirements for the AMI project. The amount of the regulatory asset, including carrying charges, is capped by the LPSC at $20.0 million. The regulatory asset will amortize by the end of the economic life of the project, currently estimated at 15 years.

Fuel and Purchased Power Costs

The cost of fuel used for electric generation and the cost of power purchased for utility customers are recovered through the LPSC-established FAC, which enables Cleco Power to pass on to its customers substantially all such charges. For the three months ended March 31, 2013, approximately 88% of Cleco Power’s total fuel cost was regulated by the LPSC, while the remainder was regulated by FERC.

The $3.9 million decrease in the under-recovered costs was primarily due to a decrease in fuel and purchased power costs.
