(c) France shall repair and maintain in good and substantial condition and, as may be necessary, shall renew all the works comprising the Gran Scala hydro-electric plant and pumping plant together with the transmission line and equipment from the Gran Scala plant to the Franco-Italian frontier. (d) France shall transmit over the transmission line from Gran Scala to the Franco-Italian frontier the electricity required by Italy as aforesaid, and shall deliver that electricity to Italy at the point at which that transmis- sion line crosses the Franco-Italian frontier into Italian territory. (e) France shall maintain the voltage and periodicity of the electricity supplied in accordance with the foregoing provisions at such levels as Italy may reasonably require. (f) France shall arrange with Italy for telephone communication be- tween Gran Scala and Italy and shall communicate with Italy in order to ensure that the Gran Scala plant, the pumping plant and transmission line are operated in such a manner as to comply with the foregoing guarantees. (g) The price to be charged by France and paid by Italy for electricity available to Italy from the Gran Scala plant (after the local requirements as aforesaid have been met) shall be the same as the price charged in France for the supply of similar quantities of hydro-electricity in French territory in the neighbourhood of Mont Cenis or in other regions where conditions are comparable. III. Duration of Guarantees Unless otherwise agreed between France and Italy these guarantees will remain in force in perpetuity. IV. Supervisory Technical Commission A Franco-Italian Supervisory Technical Commission comprising an equal number of French and Italian members shall be established to super- vise and facilitate the execution of the foregoing guarantees which are designed to secure the same facilities as Italy enjoyed in respect of hydro- electric and water supplies from the Lake of Mont Cenis before the cession of this region to France. It shall also be within the functions of the Super- visory Technical Commission to cooperate with the competent French tech- nical services in order to ensure that the safety of the lower valleys is not endangered. 1424 [61 STAT.
