Update regarding Energia del Sur, S.A. & Working Capital

Further to the announcement of 25 April 2018, the Directors of Rurelec (AIM:RUR) have been informed that the management of Energia del Sur S.A. ("EdS"), which owns and operates the 136 MW Southern Patagonian CCGT power plant in Argentina, are expecting to commence a major maintenance shutdown of its steam turbine in mid‐October 2018.

As previously announced, the EdS plant has been operating at a reduced output following the September 2017 shutdown associated with the failure of certain blades in the steam turbine. The maintenance needed to restore the plant back up to full output had suffered lengthy delays due to CAMMESA's shortage of liquidity (CAMMESA is the organisation administering and regulating the Argentinian wholesale electricity market and had agreed to provide loan finance to EdS to enable the major maintenance to take place ("Loan Finance")).

CAMMESA have indicated they will now allow EdS to make drawdowns against the Loan Finance and have made the initial payments during the course of last week to fund the first Euro €1.09 million of maintenance expenditure. Consequently, EdS's management intends to commence the maintenance of the steam turbine in mid‐October and the works are scheduled to complete mid‐to‐late December. During this maintenance, the plant will be able to continue generating power at up to 76MW from its two gas turbines operating in open cycle.

However, it should be noted that the successful completion of the maintenance of the steam turbine depends on CAMMESA funding the full budgeted sum of up to US $6.4 million. Given recent delays and the difficult conditions encountered by the Argentinian economy at present, it is possible that CAMMESA will experience further delays in approving subsequent tranches of funding needed to complete the maintenance.

Working Capital

In the announcement of 25 April 2018, it was stated that Rurelec Project Finance Limited was aiming to receive five debt repayments of $300,000 from EdS as a result of an insurance settlement. These payments were received .

Until EdS resumes full output or Rurelec sources alternative funds, or generates funds from asset sales, Rurelec's working capital position will remain severely constrained. Assuming the major maintenance results in a return to full power output in late December 2018, this should improve the cashflow of EdS from approximately February 2019 and therefore enhance EdS's ability to recommence regular repayments of debt to Rurelec Project Finance Limited. However, there is no guarantee that EdS will be able to recommence debt repayments in that timeframe. Rurelec continues to explore other funding options and will provide further updates in due course.

Further updates will be provided.
