<strong>BC</strong> <strong>Hydro</strong> and several of our larger domestic industrial customers<br />

shared benefits arising from strong export market conditions for<br />

electricity sales last year.<br />

Through our Powerex subsidiary we offered customers an<br />

arrangement known as a Custom Curtailment Agreement<br />

(CCA), whereby they reduced their electricity demand for<br />

short periods as requested by us. The additional capacity on<br />

our end allowed us to generate energy for export sales, and<br />

the customers received a share of the revenue.<br />

We received a Technology Leadership Award in 2000 for<br />

applying a pioneering process that helps large industrial<br />

customers use thermal energy more efficiently.<br />

The tool, developed by the Electric Power Research Institute<br />

(EPRI), is called Pinch analysis. The methodology determines<br />

the minimum amount of energy required to effectively run an<br />

industrial operation, and the maximum heat-recovery potential,<br />

through a review of current use and comparison against optimum<br />

performance levels for equipment and building systems.<br />

CCAs increase the ability of Powerex to trade energy in peak<br />

periods, when market prices are higher, and return the benefits<br />

to B.C. Participating in the arrangement is voluntary and does<br />

not affect domestic power supply or regular service.<br />

Beginning in October 2000, <strong>BC</strong> <strong>Hydro</strong> and seven transmission<br />

customers agreed to eleven custom curtailments and shared<br />

$1.3 million in revenue.<br />

Pinch studies are used to evaluate and streamline existing<br />

operations, and to analyze and reduce capital requirements<br />

for new equipment and process changes.<br />

After promoting Pinch analysis and its potential benefits to our<br />

customers, we worked with industry to complete six studies in<br />

1999 and four studies in 2000. The work, undertaken at large pulp<br />

and paper mills, was valued at over $2.5 million and identified<br />

potential energy savings worth more than $18.5 million per year.<br />

EPRI recognized our work to advance the process by selecting<br />

<strong>BC</strong> <strong>Hydro</strong> as its End-Use Leadership Award recipient, which<br />

recognizes efforts to promote research in field applications.
