Rules for the Calculation of the Over or Under Recovery in the Implementation of Transmission Rates by Distribution Utilities

Pursuant to Section 43(f) of Republic Act No. 9136, otherwise known
as the “Electric Power Industry Reform Act of 2001 (EPIRA)”, the
Energy Regulatory Commission (ERC) hereby adopts and promulgates these
Rules to establish a process for the calculation of the over or under
recovery in the Transmission Rates by Distribution Utilities (DUs).

ARTICLE I
GENERAL PROVISIONS

1.1 Objectives

1.1.1 To ensure transparent and reasonable prices of electric
power service in a regime of free and fair competition and to achieve
greater operational and economic efficiency;

1.1.2 To ensure full recovery of the allowable cost of Transmission;

1.1.3 To protect the public interest as it is affected by the rates and services of DUs; and

1.1.4 To ensure and maintain the quality, reliability, security and affordability of the supply of electric power.

1.2 Scope

1.2.1 These Rules shall apply to all DUs that are connected to the Grid.

1.3 Definition of Terms

Act – unless otherwise stated, shall refer to
Republic Act No. 9136, otherwise known as the “Electric Power Industry
Reform Act of 2001;

Distribution Utility – shall refer to any
electric cooperative (EC), private corporation, government-owned utility
or existing local government unit which has an exclusive franchise to
operate a distribution system in accordance with the Act;

Energy Regulatory Commission or ERC – shall refer to the independent, quasi-judicial regulatory agency created under Section 38 of the Act;

Net Transmission Cost- shall refer to the total
charges of National Transmission Corporation (TRANSCO), or its buyer or
concessionaire, including, but not limited to, transmission and
sub-transmission costs, ancilliary service, connection service and power
cost delivery service net of any imbalance charges, cost associated
with the availment of the One-Day Power Sales (ODPS), and value added
tax associated with the transmission service. Net transmission costs
shall include only those costs that are prudently incurred, actually
paid for, verifiable, reasonable, and are eligible for recovery in
accordance with the ERC’s Rules and Regulations.

Transmission Rates – for the
purpose of these Rules, shall refer to the charges associated with the
transmission cost incurred by the DU which have been determined by the
ERC in the DU’s Unbundling of Rates Application.

ARTICLE II
CALCULATION OF OVER OR UNDER RECOVERY IN TRANSMISSION

2.1 One- Time Determination

The transmission rates paid by the DUs prior to the effectivity of
these Rules were fixed annually for four (4) years which incorporated
the removal of the intra-grid cross subsidies of TRANSCO as provided in
the approved unbundled rates of the DUs. The Commission shall allow the
one-time determination of the over or under recovery on the DU’s
transmission charges from the time the DUs implemented their unbundled
rates up to the effectivity of the “Guidelines for the Adjustment of
the Transmission Rates by Distribution Utilities” (TRAM Guidelines).

2.2 Adjustment Formula

The calculation of the over or under recovery in the
implementation of the transmission rates to effect the “refund” or
“collect” thereof from the time the DUs first implemented their
unbundled rates up to April 2006 or the month before the DUs were able
to implement new transmission rates in accordance with the TRAM
Guidelines, shall be based on the following formula per customer class:

Transmission Over or Under RecoveryN (PhP/kWh) =	Total Over or Under RecoveryN Σ KWh Sales Ni i = 1…n
where: Total Over or Under RecoveryN (PhP) =	Σ i [(Allowable Transmission Cost –Ni i=1…n Transmission Recovery Ni)]
Allowable Transmission CostNi =	Allowable Transmission Cost of SalesNi
Allowable Transmission Cost of SalesNi=	(Transmission Cost – NPFD x 50%) Total Purchased kWhi
	X Total kWh Salesi x CPN
I =	refers to month 1, month 2 until month n, where month 1 refers to the month the DU implemented its unbundled rates and month n refers to the month prior to the implementation of the TRAM Guidelines
N =	refers to a specific customer class (ex. N=1,2,…., where 1= Residential, 2= Commercial, etc.)
Transmission RecoveryNi =	(Transmission Charge in PhP/kWh x kWh SalesNi) + (Transmission Charge in PhP/KW billing demandNi)
Transmission Costi =	the actual net transmission cost in PhP for the month i
NPFD =	Where:
	Gross Power Factor Discount availed by the DU from TransCo	PhP XXX
	Less: (1) Power Factor Discount Granted by the DU	XXX
	(2) The amount paid by the DU under a business agreement with a third party for the improvement of its power factor*	XXX
	Net Power Factor Discount (NPFD) Multiplied by (Percentage share)	XXX __50% __
	NPFD to be passed on by the DUs to its customers	Php XXX
	Note:* shall not exceed 50% of Gross PFD
Total Purchased kWH =	kWh purchases from all suppliers that correspond to the kWh sales billed the transmission charge for the month less ODPS
Total KWh Salesi =	Total kWh sales of the DU for the month i
CPN =	Coincident Peak allocation factor for customer class N as reflected in the last approved unbundled rates of the DU
Transmission Charge in PhP/kWh and PhP/kW =	Transmission charge in PhP/kWh and or PhP/kW as applicable to customer class N and provided in the Unbundling Decision of the DU. If the transmission charge for customer N is expressed in PhP/kWh only, then the Transmission Charge in PhP/kW in the formula should be equal to zero (0)
KWh SalesNi =	Total kWh sales for customer class N for the month i
KW SalesNi =	Total kW billing demand for customer class N for the month i

The calculation of the over or under recovery in the Transmission
Rate per customer class shall be expressed in PhP/kWh for customer
billed on a per kWh basis or a combination of per kWh and per kW and
PhP/kW for customer billed on a per kW basis in accordance with the
formula provided in 2.3 hereof.

2.3 Billing of the Over or Under Recovery in Transmission Rates

Any over or under recovery as may be approved by the ERC shall be
implemented by the DU by incorporating the rate in the existing
transmission rates component (in PhP/kWh) of the DU’s customer bills.
However, if the existing transmission rate component of a DU to its
specific customer class is in PhP/kW, the calculated PhP/kWh can be
converted to PhP/kW using the following formula:

PhP/kW =

_______________Calculated PhP/kWh________ 1/[load factor x {(365 days/yr x 24 hrs/day)/12 mos/yr}]

ARTICLE III
FILING REQUIREMENTS
