production is solid fuels, either brown coal or lignite, while 36 percent of its electricity<br />

comes from nuclear energy." **<br />

Bulgaria has already closed its two oldest nuclear power reactors temporarily, but<br />

has argued that it needs the power from the remaining four.^° Because of Bulgaria's<br />

unique dependence, its reactors could be phased out a little more slowly than in<br />

other nations. Its two oldest, currently operating reactors, both model 230's, contribute<br />

an effective generating capacity of 659 MW, (the two closed reactors normally<br />

contribute 604 MW) while its two new reactors, still three to four years from peak<br />

production, have a total capacity of 1906 MW.^*<br />

Like the other nations of Eastern Europe, Bulgaria uses more energy than other<br />

OECD nations per unit of output, according to World Bank statistics: Bulgaria is<br />

five times more energy intensive than the former nation of East Germany, and<br />

more than twice as intensive as the OECD average. ^^ Data from the AID study<br />

shows that emergency energy assistance to Bulgaria in the past has saved considerable<br />

amounts of energy. Ck)nsidering improvements to only three types of facilities<br />

(iron/steel mills, poultry slaughterhouses, milk factory), the investments in approximately<br />

10 plants ^^ resulted in an estimated net savings of $184,761 ^^ per year; for<br />

each investment, the simple payback period was just three and a half months. A<br />

total of 2580 TOE, or .116 PJ was saved over just a few facilities. ^^<br />

Further, the costs of choosing nuclear power over a strategy empheisizing energyefficiency<br />

increase substantially in the case of Bulgaria, because its Kozloduy station<br />

is in exceptionally poor operational and structural condition.^® The poor management<br />

practices prevalent at that nuclear installation dictate a switch to increased<br />

efficiency at other power facilities.<br />

The current economic contraction in Bulgaria poses an unparalleled opportunity<br />

to restructure patterns of energy production. Since 1988, electricity consumption has<br />

fallen from 49.2 billion kWh (49,200 GWh) to 40 bUlion kWh (40,000 GWh). These<br />

trends should continue until the middle of this decade.®'' As a result, in the encouragement<br />

of renewed consumption, industry can focus on energy efficiency, which<br />

can enable the economy to produce more, at less cost, without waiting for expensive<br />

increases in energy output.<br />

5. Particular Opportunities In CSFR<br />

a. Conservation Potential<br />

CSFR nuclear plants produced 2717 MW (23.8 TWh, or 85.68 PJ ^s) in 1991, or<br />

29.4 percent of that nation's total electricity. ®® Unlike Bulgaria and Hungary, CSFR<br />

produces 70 percent of its own energy. In addition, its economic restructuring has<br />

proceeded very rapidly: although prices are still centrally determined by the two republics,<br />

the prices charged to industry reflect international prices. ^°° 'This increase<br />

in prices will be particularly effective, because industry consumes 50 percent of all<br />

energy. *°i Since industry will be especially cash-starved over the next few years,<br />

management will wish to scale back consumption dramatically in order to cut<br />

costs. ^°^<br />

A study by SEVEn,^°3 the Energy Efficiency Center in Prague concludes that 701<br />

PJ i°* (more than eight times the amount required to replace nuclear power) may<br />

be saved every year with retrofitting in particular industries. The retrofitting of furnaces<br />

alone is projected to save 259 PJ/year, while efficiency improvements in secondary<br />

energy sources contribute an additional 350 PJ/year. Decentralizing the<br />

electricity production system will help minimize waste. The use of small cogeneration<br />

plants (according to the SEVEn study, current technology makes possible units<br />

of approximately 100 kW).'°^ In addition, larger-scale cogeneration technologies,<br />

which involve the backfitting of plants to support combined heat and power production,<br />

require little start-up time and can use indigenous production facilities.'"^ As<br />

a final improvement in the electricity generation industry, old plants in Slovakia<br />

could be upgraded. Particularly, improving the efficiency of three fossil fuel powerplants<br />

from 30 percent to the western level of 42 percent would save approximately<br />

800 MW, and would allow the closure of 2 reactors in Bohunice.*"''<br />

The state has already begun to consider some of these options. CSFR has begun to<br />

study efficiency alternatives, while the utilities in both the Czech and Slovak republics<br />

have begun to study least-cost approaches to planning in electricity generation<br />

and distribution. These approaches emphasize energy efficiency as a more economical<br />

approach to power generation. i°* The total savings in the industrial sector is<br />

estimated to be one-third of total energy consumption.'"® This exceeds the level of<br />

savings necessary to shut down every nuclear plant.<br />

These estimates include only the industrial sector; the residential sector provides<br />

new opportunities for energy efficiency. Although industrial energy prices approach<br />

those of Western Europe, prices in the residential areas are two to three times
