The main focus is on the regulation of private operators since many provincial governments are considering concessioning all or part of these services to the private sector to improve quality and rely more on private financing of the sectors' expansion needs. Tariff design and institutional concerns are emphasized in a detailed analysis of the specific regulatory framework of both sectors, including some issues raised by federal regulation relevant to the decisions of potential investors in provincial utilities. Main conclusion. The report strongly endorses the general concessioning strategy followed by most provinces. This strategy has already generated substantial gains in utilities under Federal control. In electricity for instance, tariffs have slightly decreased on average since privatization and quality of service have improved significantly. For instance, the average number of annual service interruptions was cut from at least 7.6 to 5, and the average duration from 23 hours/year to 9.9 hours/year. However, not all provinces will be able to follow a strategy relying on private investors as they vary tremendously in terms of potential rate of return and commercial as well as non- commercial risks (including political and fiscal risks). Some of the poorest provinces combine low potential return and high risks' levels and are unlikely to be very attractive under deals and regulatory arrangements that try to shift most of the risk onto the private investors. For these provinces or for those not wishing to transfer outright the W&S and electricity distribution services to the private sector, the report offers alternatives. It suggests, in the short run, the commercialization of these services through management and service contracts with private companies can serve to establish the credibility of the provincial commitment to reform. But this should be viewed as a first step towards the implementation of concession as it gives investors a chance to obtain more independent information on the value of the assets for which they would be bidding The keys to successful provincial utilities reforms. The National Reforms demonstrate that to maximize the gains from the "privatization" strategy, the following steps are needed: * make the most of what competitionfor the market allows, * give an incentive to new owners to remain concerned with the public interest; * assign rights and obligations in the contract as clearly as possible, * anticipate the potential needs for renegotiation; * define the nature and form of property to maximize accountability, * do not underestimate the importance of tariff design; and * prepare and develop the provincial regulatory capacity as carefully as the contract. ii Do not underestimate what can be achieved through competition for the market. Whether in the area(s) of operations, management or specific services, competition for the service is crucial to the success of the current reform efforts. Competition and increased private sector involvement also reduce arbitrary political interference in price setting or employment decisions, for instance. Although the specific form of private sector involvement in each province will have to be tailored to fit local needs, constraints and preferences, the introduction of competition, if implemented correctly, will cut total service costs, pass a large share of these cuts to all consumers and improve responsiveness to users. The success of the approach (in terms of fiscal impact but also in terms of service quality and price) depends a lot on the design of the bids to assign the operator's role in a concession, management or service contract. Some of the provinces are clearly aware of the importance of this step in the reform process: it ensures the credibility of the provinces' announcements and their commitment to change. For instance, the province of Santa Fe commissioned an independent assessment of the value of the net assets of its utilities (done by an internationally recognized external expert). This provided independent information on the potential fiscal impact of the reform. It also revealed up front as much reliable information as possible to potential investors. This type of assessment can also avoid some uncertainties in terms of rehabilitation needs and reduce the risk of unexpected tariff adjustments as those approved for Aguas Argentinas over and above what was agreed in the original contract. Ensure the managers' and workers' accountability. If property is distributed, the way it is done can also contribute to the success of the reform. Shares can be sold on the stock market to widen the dissemination of property and hence of accountability as was once considered (but eventually rejected) for Aguas Argentinas. Shares can also be allocated to workers and employees, as for electricity transmission under federal jurisdiction, giving them an effective incentive to support the reform and to act in the interest of the enterprise. But there are risks in spreading accountability too thinly. This is why it is generally suggested to allow the bidding of packages of shares large enough to allow control by one major interest i.e., to have a strategic investor. Clearly spell out the rights and obligations of all parties. Under the strategy adopted by the provinces, contracts (concession, management or services) are the main regulatory instrument during the tenure of the private operator. Where and when governments do not have a long track record in dealing with the private sector, contracts need to be drawn as tightly as possible to reduce opportunities for discretionary government actions. Contracts are intended to be enforced according to their terms. The provincial reforms will only work if the provincial governments recognize that once a private operator takes over, this operator is in charge within the specific terms of its contract. Anticipate the potential needs for renegotiation. Even if a province has well prepared its contracts, unforeseen events will happen. This means that even if contracts should be prepared as documents that are not intended to be modified and include adjustment mechanisms to avoid the costs and uncertainty of renegotiation, under very specific and very limited circumstances, a limited degree of contract flexibility may be good public policy. To ensure that the contract is a credible regulatory instrument, contract modifications should be based on some fair and workable rules based on clearly spelled out policy criteria (discussed in the report). These rules should be agreed upon by all involved parties, and the guarantee of this agreement should be provided by an independent regulator as an honest broker. Unilateral modification of the rights defined in the contract or the bidding documents (say through request to accelerate investment programs or impediments to tariff adjustments) without iii full compensation is tantamount to expropriation and defeats the purpose of the reform. It is the risk of arbitrary government behavior of this kind that historically created the biggest risk for private investors in infrastructure and that continues to deter many deals. Keep the new private monopolies working in the public interest. Once the contracts have been awarded, it may be difficult for the government to get the private operator or managers to focus on the interest of consumers as much as on their own interest. To maximize the incentive for efficient behavior during the concession, the contracts can require that new auctions be organized at regular intervals as it was done in the case of the electricity distribution concessions orchestrated by the National Govemment. Another incentive for provincial monopolies to maintain their concern for the interest of consumers is to rely on some formal comparison of performance across provinces. These comparisons should be widely disseminated (in the media) to increase the public pressure for accountability. These comparisons can also be used more formally by regulators to push prices to their lowest possible level ("yardstick competition"). This requires a strong inter-provincial coordination to standardize information which could be organized by the National Regulators. Get the tariffs design right. All reformers recognize that the design of tariff formulas are at the core of effective regulation. However, few appreciate its complexity and relevance to the long- term sustainability of the provincial utility reforms. The report discusses how tariff design matters to ensure the best allocation of scarce provincial resources. In the context of this analysis, it identifies a few issues that deserve their immediate attention. Some of these issues are under their direct control and should be handled as part of the reform process. Some are under the responsibility of the National Government but need to be monitored by provincial reformers to allow them to anticipate the concerns of potential investors in provincial utilities. In Electricity, the provinces trying to introduce more efficient pricing of distribution services (including an incentive to maximize productivity gains) should adhere to the tariff methodology contained in the national electricity law with some adjustments. Chapter 2 shows that: * If regulation continues to be based on price capping (aims at giving incentive to minimize costs), there is a need to very quickly define a methodology and gather the information needed to calculate the productivity gains that should be passed on to consumers. * There is also a need to review the current tariff methodology in order to make sure that the interest of "captive consumers" are protected. The current approach creates a distortion due to the possibility of direct contracts between "large users" and "generators". The consequence of these contracts is that captive consumers (i.e., those who are not large enough to be able to buy without having to go through the distribution companies) may have to pay much higher rates because they are paying for more expensive wholesale contracts transferred at the time of privatization and large users opt out to negotiate cheaper contracts in the wholesale market. This could lead to difficult political problems as "privatized" tariffs may end up increasing significantly in relative terms for a large share of the consumers. This could be avoided by allowing some more pricing flexibility and some degree of discrimination in prices. In addition, the provincial governments will have to monitor the developments in transmission pricing, one of the very few serious outstanding issues in the otherwise very impressive National Sector Reform. Better and clearer rules (based on economic benefits rather than on energy flows) are iv needed to avoid the type of difficulties recently met in discussions of the construction of a fourth transmission line in the Comahue corridor. Existing rules have a bias towards underinvestment because they fail to assign a clear responsibility for the payment of the construction costs of any expansion. Since transmission is the physical instrument to guarantee competition in generation and supply, this underinvestment is increasingly a concern to potential investors in distribution. Moreover, as more and more provinces privatize their distribution companies, the relationship between the transmission concessionaires and the distribution concessionaires is likely to change, and the tolls may have to be revised to ensure consistency with economically efficient pricing rules and revenue adequacy. In W&S, Chapter 3 shows that the regulatory challenge is much wider and complex: * A radical tariff reform is needed to achieve efficiency in the use of water and to finance growing long-term investment needs, particularly in the sewerage systems. It will involve increased metering, eliminating the current tariff for unmetered consumption and redesigning the fixed part of the current two-part tariff used for metered consumption, since it currently leads to multiple types of cross subsidies, and since it fails to provide much incentive to minimize cost and to invest in the expansion of the sewerage system. * This tariff reform will have to be implemented as part of a wider reform which should aim at the adoption of commercial practices in the sector. This means that the provincial governments will have to give up many of the controls they are now imposing on their public enterprises and aim at regulatory simplicity when identifying what needs to be controlled/regulated and what need not be (and this will require strong coordination with the National Government). * The concerns with the high level of uncertainty regarding the asset value and the costs of the rehabilitation needs expressed by potential private investors interviewed by the Bank are such that some of the provinces will have to consider a slower pace of reform, and will have to focus on short-term management contracts with an option to transform them into concession contracts in the longer run. It may also be worth considering the bundling of W&S assets across provinces, or their bundling with other assets such as electricity to reduce the overall risk faced or perceived by private investors. None of this should affect the efforts to reform tariffs and increase metering. Develop the provincial regulatory capacity. The most difficult provincial challenge addressed in the report may be the need to monitor that the behavior of the privatized monopolies are consistent with the terms of the contract as well as with public aims. This monitoring is needed because concessionaires will have strong incentives to behave inefficiently when left unsupervised. The creation of regulatory bodies or the use of the strength of law and courts will be an important element in the success of the provincial reform of utilities and Chapter 4 focuses on this exclusively. But there is a need to distinguish between technical and economic regulation in both sectors. Economic regulation does not have the same goals as technical regulation so that its organization is not necessarily identical to the technical one. For the electricity sector, the difference can be illustrated as follows: at the terminal nodes of the interconnected electric network there is little need for technical control, but it is a place where provincial distributors can try to exploit their exclusive position in front of captive consumers and hence economic regulation may be needed even if technical regulation is not. Therefore, the skills needed to develop the provincial regulatory capacity are not simply a recycling of the skills needed to provide the service in a public enterprise. Some of the staff v of the former public utility will have to be dismissed and new staff will have to be recruited to introduce these new skills in the provincial regulatory entities. Aim at a single independent sector specific agency. While the Report shows that some economic regulatory responsibilities may be justified at the provincial level in electricity and W&S even when technical regulation is not needed, it also shows that if each province must have its own regulatory capacity, the local entity should be kept to a minimum and only have specific prerogatives, essentially auditing and reporting to the national regulation body. This is particularly important in electricity because technical dependencies within the network are very strong. Moreover, the recognition of a role for provincial regulation is not an endorsement of the creation of multiple sector specific regulatory agencies. The international experience suggests that most provinces would be better off with a single independent entity for all utilities. Chapter 4 explains in detail how to achieve that independence in terms of nomination of regulators and financing of the agency. Do not simply staff the agency with the employees fired by the private operator. The staffing level of the agency should be modest and its composition should depend on the requirements of specific tasks assigned to the regulatory agency. As discussed in the Report, there are many good possible criteria for selection (i.e., technical excellence, political representation, ...). With a few exceptions, the experience considered relevant in the staffing process at the national level was based on engineering aspects of the sector while economic regulation, the main purpose of these entities, is quite different from technical regulation. This suggests that the selection criteria for the regulators should include expertise in economic fields. While the skills needed to be a good regulator are hard to find, they are very similar in both, the water and electricity sector, and hence the same resources can be shared within a single provincial regulatory entity. This means lower resource needs (not only in terms of staff but also in terms of equipment) and hence a lower burden on the taxpayers or the beneficiaries of the services. There are other benefits. For instance, it facilitates learning between sectors, ensures consistent approaches to central policy questions, and makes the regulator less vulnerable to industry or political capture. This lower vulnerability enhances the credibility of the agency and reduces risks for investors. Spell out the implementation strategy. The strategy to implement this regulatory agency can be flexible. If no agency has been established yet, a core multisectoral framework can be set up first and then sectors can be added to the core entity when appropriate. There is no need to wait until any contract has been signed. The creation of an entity can be instrumental in assisting in the implementation of the concessioning process. If one agency has already been established, it should not be too difficult to expand the jurisdiction of the existing agency. This depends of course on how sector specific in design and composition the initial agency is. Finally, if several agencies have already been created, the best option is to develop a strategy for merging the agencies after an initial period. This strategy tends to be the most difficult and will often be resisted by both the existing regulators (concerned about losing their autonomy and possibly their job) and investors (often preferring the counterpart they know). Next Steps. The main conclusion of this report is that there is no single blueprint for the provinces but that there is strong evidence of a need to further understand regulatory objectives and establish regulatory rules and regulatory behaviors whatever the specific strategy adopted by a province. The ultimate aim is better and cheaper service provisions to the Argentine consumer, vi whether she/he lives in Bs.As. or Salta or Tierra del Fuego. The Report also aims to be a discussion report, namely a vehicle to raise issues and begin the public dialogue necessary to extract the benefits of a private sector participation in key utilities in Argentina's provinces.

This avoided some (but not during the concession, the concession contracts all) of the uncertainties in terms of rehabilitation awarded by the National Government in electricity needs observed in the privatization of Obras require that new auctions be organized at regular Pfiblicas in Buenos Aires.

In the case of Aguas Argentinas, shares return in the sector before and after the inclusion of the new firm were sold on the stock market to widen the can also provide useful insights on the potential financial impact of the privatization. Typically, utilities are expected to be below dissemination of property and hence of average risk and their return should vary by less than the market accountability. For electricity transmission, shares average. If the bids show anything else, it may reveal that the were allocated to all staff, giving an incentive to bidder is asking for too much to provide the service. It may also reflect an attempt b the bidder to compensate for a province act in the company's interest. But there are also specific risk that is well above market average. In this case, the risks in spreading accountability too thinly. This specific form of regulation may need to be tuned up as discussed is why it is generally suggested to allow the later in the chapter bidding of packages of shares large enough to allow control by one major interest (i.e., to have a strategic investor). 4 While reducing the problems due to monopolies, this approach still implies a need for regulation.
