I. INTRODUCTION
The increasing globalization of the economy in general brought along a rising interdependence between exporters and importers of energy. Announcements have been made of large-scale projects in South America that will create cross-border energy chains and capital flows. In this scenario, energy is viewed as a strategic resource within a national energy policy and governments have taken steps towards playing a strategic role. Energy integration appears to be a relevant aspect of a common national policy to strengthen the relationship between South American nations. By the same token, any changes to the domestic energy regulatory framework will have repercussions across the border.
The purpose of this paper is to focus on cross border disruptions of natural gas between Chile and Argentina its implications to both the mining and the oil/gas industries and how this issue is being addressed by the governments and by the private sector. A description of the legal rules related to cross border disruption is presented.
An exhaustive review of the Chilean and Argentine natural gas legal framework is not attempted. The legal implications of cross border disruptions for long-term contracts are addressed to draw conclusions to promote a favorable framework for regional integration. Issues specific to potential country or private party responsibility associated with disruption is not to be part of this paper.
Taking the case of Chile and Argentina as an example, this paper reflects on the implications for long term contracts, and on the opportunity to create a stable cross border environment that should protect both the necessary investment flow as well as the energy security policy.
II. CHILEAN APPROACH
Development of Mining Projects in Chile has been tightly associated with the existence of energy allowing the construction and operation of such projects, very often located just in the middle of the desert and away from cities.
As expected, each of these projects represents a major-long-term goal involving not only extraordinary efforts in term of human capacities and engineering, but also the investment of billions, made with the aim of getting a profitable rate of return.
[Page 2-2]
These projects also demand a huge consumption of energy and therefore mining business is very focused on the different sources of energy available for its development.
This development also requires the existence of a clear and stable legal framework giving the confidence that the investments to be made are well protected.
Until 1995 the composition of the Chilean Primary Energy Matrix was based mostly on the use of crude oil, hydroelectricity, wood & others and coal. The use of natural gas was in the last place.
On 2005 the composition of the Chilean Primary Energy Matrix varied having natural gas as a key supply source, increasing its participation from 8,7% in 1995 up to 23,8% in 2005.

Annual growth of energy consumption 1995-2005: 4.5% (GDP growth: 3.6%)
Likewise, until 1995 the Chilean Electricity Matrix was composed mainly by hydro, coal, dieselfuel and others, but no natural gas at all, while on 2005 the composition of the Chilean Electricity Matrix varied having natural gas as a key supply source, increasing its participation from 0% in 1995 up to 36% in 2005.

The above was not only the result of the lower costs attached to the use of natural gas and the viability to import natural gas from Argentina to Chile, but also it was the result of several agreements and protocols signed between Argentina and Chile, which defined a common market between these countries related to export/import of natural gas.
The execution of these agreements and protocols and the legal framework they created was an encouragement for the construction of gas pipelines, electricity generating plants, distribution nets along other significant cross border investments made between these countries.
Likewise the execution of these agreements and protocols lead, during the late 90s, to the negotiation of new long term energy supply agreements among, and almost, all Chilean mining operations with the energy producers and gas importers.
1. Highlights of the Chilean Electric System
Nowadays, Chile imports nearly 72% of the resources necessary to produce the energy it consumes and its electric matrix is divided into 3 systems, which are:
a) Sistema Interconectado del Norte Grande (SING): This system represents 30,01% of the national capacity, with a generating potential of 3.595,8 MW.
It applies to the North region of Chile and 90% approx. of this energy is destined to the mining and industrial sectors and the remaining 10% to regulated or residential costumers.
Its service area is primarily rural northern Chile which accounts for approximately 6.2 per cent of the country's population. Its main energy source is gas.

Of the 2,100 MW gas-fired installed capacity in the SING, 1,120 MW have dual systems and can operate with diesel in case of gas cuts

b) Sistema Interconectado Central (SIC): This system represents 69,17% of the country's energetic capacity, with a generating capacity of 8.288,3 MW. It applies to most part of the territory, from regions III to X and its main energy source is hydro electrical energy (58,6%).
SIC: Hydro Dependence
Hydroelectricity accounted for almost 60% of the SIC's installed capacity in 2005.

c) Systems of Aysén and Magallanes: Both present similar characteristics, as they are not provided of interconnected transmission nets. They respectively represent 0,28% and 0,54% of the national installed capacity.

2. Highlights of the Chilean Legal Framework
a) Public-Technical Services Run by Privates. The applicable legal framework varies depending of the energy cycle: generation, transmission and distribution. Notwithstanding these three stages have the character of public service, they are given to the management and exploitation of private agents, but having the State a strong regulatory role focused on the planification, control, monitoring and supervision of...
