The Philippine transmission business is regulated under Performance Based

Regulation (PBR) using a revenue cap approach

Adopted in May 2003 by the ERC thru its promulgation of the Transmission Wheeling Rate Guidelines (TWRG)

TransCo

Rationale for PBR

EPIRA Sec. 43(f) In the public interest, [ERC shall] establish and enforce a methodology for setting transmission and distribution wheeling rates xxx, taking into account all relevant considerations, including the efficiency and inefficiency of the regulated entities

TransCo

PBR is a form of utility regulation

that strengthens the financial

incentives to lower rates, lower cost,

or improve non-price performance

relative to traditional regulation.

What is Performance Based Ratemaking (PBR)?

TransCo

Why Adopt PBR Now?

Costs are more predictable. Ability to stabilize revenues and earnings

over multi-year period. Rate case avoidance for multi-year PBR

plans. Opportunities to be rewarded for cost

cutting and efficiencies. Incentives for market/technology risk

taking.

TransCo

PBR vs Cost Based (RORB) PBR

Ex-ante cost (forecast data and ‘time-value-of-money’). Uses pricing formula independent of cost. Provides incentive for utility to lower costs and rates. Creates opportunity for a utility to earn additional profits by reducing

costs or improving service. Reduces regulatory delays and cost. Sets measurable targets for reliability & safety and provides

incentives for meeting the targets/standards. RORB

Ex- post cost (historical data). Uses fixed rate of return in computing revenue requirement. Cost based rates. No guaranteed rate of return (potential to overspend) . Short-term incentives to reduce costs since benefits on cost

reductions are kept by stakeholders until the next rate case where benefits eventually flow to consumers.
