Tokyo, Japan

Tokyo Electric Power Company, Incorporated , also known as Toden or TEPCO, is a Japanese electric utility servicing Japan's Kantō region, Yamanashi Prefecture, and the eastern portion of Shizuoka Prefecture. This area includes Tokyo. Its headquarters are located in Uchisaiwaicho, Chiyoda, Tokyo, and international branch offices exist in Washington, D.C., and London. It is a founding member of strategic consortiums related to energy innovation and research; such as JINED, INCJ and MAI.In 2007, TEPCO was forced to shut the Kashiwazaki-Kariwa Nuclear Power Plant after the Niigata-Chuetsu-Oki Earthquake. That year it posted its first loss in 28 years. Corporate losses continued until the plant reopened in 2009. Following the March 2011 Tōhoku earthquake and tsunami, its power plant at Fukushima Daiichi was the site of a continuing nuclear disaster, one of the world's most serious. TEPCO could face ¥2 trillion in special losses in the current business year to March 2012, and the Japanese government plans to put TEPCO under effective state control to guarantee compensation payments to the people affected by the accident. The Fukushima disaster displaced 50,000 households in the evacuation zone because of leaks of radioactive materials into the air, soil and sea.In July 2012 TEPCO received ¥1 trillion from the Japanese government. TEPCO's management subsequently made a proposal to its shareholders for the company to be part-nationalized. The total cost of the disaster was estimated at $100bn in May 2012. Wikipedia.

PERTH, WESTERN AUSTRALIA --(Marketwired - May 16, 2017) - Paladin Energy Ltd ("Paladin" or "the Company") ( : PDN) (TSX: PDN) announces the release of its condensed consolidated interim financial report for the nine months ended 31 March 2017. The condensed consolidated financial report is appended to this News Release. References below to 2017 and 2016 are to the equivalent nine months ended 31 March 2017 and 2016 respectively. Results (References below to 2017 and 2016 are to the equivalent nine months ended 31 March 2017 and 2016 respectively). Safety and sustainability The Company's 12 month moving average Lost Time Injury Frequency Rate(5) (LTIFR) increased to 2.2 as compared to 1.9 at the end of the last quarter. The 12 month moving average LTIFR for the previous year was 2.2. Three Lost Time Injuries (LTI) were reported during the nine months at LHM: a process operator sustained an injury to the right ankle descending a fixed ladder, a maintenance tradesman injured a shoulder while using a drill and a process operator sustained a chemical burn to the foot when entering a flooded bund with inappropriate personal protective equipment. The Company achieved 999 Lost Time Injury (LTI) free days at the Kayelekera Mine (KM) for ~1.7 Million man hours. Langer Heinrich Mine (LHM) LHM produced 3.396Mlb U O for the nine months ended 31 March 2017, down 7% from the previous year (2016: 3.644Mlb U O ). The unit C1 cost of production for the nine months decreased by 32% from US$25.65/lb in 2016 to US$17.51/lb in 2017 primarily due to a strong operating performance and the impact of the write-down of LHM's ore stockpiles that occurred at 30 June 2016. Profit and Loss Total sales volume for 2017 was 2.856Mlb U O (2016: 3.094Mlb). Sales revenue for 2017 decreased by 43% from US$121.9M in 2016 to US$69.4M in 2017, as a result of a 38% decrease in realised sales price and an 8% decrease in sales volume. The average realised uranium sales price for 2017 was US$24.32/lb U O (2016: US$39.41/lb U O ), compared to the TradeTech weekly spot price average for the period of US$23.10/lb U O . Gross loss for the period decreased by 186% from a gross profit of US$25.7M in 2016 to a gross loss of US$22.2M in 2017 due to a 38% decrease in realised sales price, an 8% decrease in sales volume, and an impairment of inventory of US$26.7M (2016: US$Nil), which was partially offset by a 33% decrease in cost of sales. Impairments of inventory of US$26.7M were recognised in 2017 (2016: US$Nil) Impairments comprise of a US$18.4M impairment of LHM ore stockpiles, US$5.1M impairment of LHM product-in-circuit and a US$3.2M impairment of finished goods due to low uranium prices. Net loss after tax attributable to members of the Parent for 2017 of US$84.0M (2016: Net loss US$39.3M). Underlying EBITDA has deteriorated by US$11.1M for the period from an underlying EBITDA of US$16.2M for 2016 to US$5.1M for 2017, mainly due to a 38% decrease in the realised sales price. Cash flow The Group's principal source of liquidity as at 31 March 2017, was cash of US$21.8M (30 June 2016: US$59.2M). Any cash available to be invested is held with Australian banks with a minimum AA- Standard & Poor's credit rating over a range of maturities. Of this, US$19.5M is held in US dollars. Cash outflow from operating activities was US$43.7M in 2017 (2016: outflow US$35.4M), primarily due to payments to suppliers and employees of US$111.7M and net interest paid of US$14.6M, which were partially offset by receipts from customers of US$70.5M and the receipt of US$12.7M of unearned revenue from the prepayment of sales. Cash outflow from investing activities for 2017 was US$3.7M (2016: US$3.8M): Cash inflow from financing activities was US$9.6M in 2017 (2016: outflow US$122.5M), was attributable to the drawdown of US$20M under the LHM secured Revolving Credit Facility, which was partially offset by a US$10.4M distribution to CNNC by way of repayment of intercompany loans owing by LHM that have been assigned to CNNC. Cash position At 31 March 2017, the Group's cash and cash equivalents were US$21.8M, which was above the guidance range previously provided of US$10M to US$20M. The documents comprising the condensed consolidated interim financial report for the nine months ended 31 March 2017, including Management Discussion and Analysis, Financial Statements and Certifications are attached and will be filed with the Company's other documents on Sedar (sedar.com) and on the Company's website (paladinenergy.com.au). The TradeTech weekly spot price average for 2017 was US$23.10/lb, a fall of 34% compared to the weekly spot average for 2016 average of US$35.08/lb. Following price increases at the start of the calendar year, uranium spot price has traded over a range of $21.15-$26.50/lb since late January and currently stands around $21.25/lb. US reactor vendor and nuclear fuel services company Westinghouse Electric Co. filed for Chapter 11 bankruptcy protection on 29 March 2017. The company, a subsidiary of Japan's Toshiba Corporation, is seeking to restructure its business to address financial losses and ongoing construction challenges at its US nuclear power plant projects. The US projects, four AP1000 units under construction at Vogtle in Georgia and VC Summer in North Carolina, now may face additional delays or even curtailment. In Asia there have been positive developments in the process to restart Japanese reactors. In late March, the Osaka High Court overturned an injunction that had been preventing operation of Kansai's Takahama Units 3 and 4 since it was imposed by a lower court in early 2016. The two units are anticipated to restart in May after completion of planned maintenance checks. A court in Hiroshima denied an injunction seeking to shutdown Shikoku's Ikata Unit 3. This reactor was returned to service in September 2016. In April, Tokyo Electric Power Co. announced it plans to restart reactors at its Kashiwazaki-Kariwa nuclear power plant in Kashiwazaki, Niigata Prefecture in early 2019. The Kashiwazaki-Kariwa plant is one of the world's largest nuclear power stations in terms of output capacity. The board of directors of Électricité de France resisted government pressure to announce the permanent closure of France's oldest reactor Fessenheim. In response, the government issued a decree specifying that the plant must close once the new Flamanville 3 plant comes into operation. Fessenheim's ultimate fate may now be decided by the winner of the current French presidential election. Paladin remains hopeful that a recovery in the uranium market is underway, albeit in its early stages. However, anticipated utility activity has been slow to manifest and future spot price increases and stability remain reliant on a more substantive re-engagement by utility end-users of uranium. Company strategy Paladin believes a uranium industry turnaround is imminent. However, given the current low pricing environment, its current strategies are focused on optimising actions to maximise cash flow whilst also prudently enacting capital management actions. Paladin's strategies are aimed at maximising shareholder value through the uranium price downturn whilst remaining positioned for a future normalisation of the uranium market and price. Key elements of the Company's strategy include: Company outlook LHM's adjusted Life of Mine plan (LOM) was implemented in November 2016, which involves reducing mining material movement combined with processing plant feed coming from stockpiled low and medium grade ores. The revised mine plan effectively shifts higher-grade ore processing into later years when uranium prices are expected to be higher. The FY2017 average feed grade will be reduced into the range of 550ppm to 570ppm vs our previous internal Company budget of 700ppm. The impact of the change will reduce finished U O production by up to 1.0Mlb to 1.5Mlb per year for each of the next two years. However, the requirement for less movement of mined material on site during the period reduces cash operating costs by well in excess of any lost revenue. Using Paladin's internal assumptions the initiative will generate approximately US$40M of cumulative incremental operating cash flow for FY2017 and FY2018.

BANGKOK, April 27, 2017 /PRNewswire/ -- Asian Utility Week, a brand belonging to Clarion Events, takes place at Impact Arena, Exhibition & Convention Center, Bangkok, Thailand on 24-25 May 2017. Asian Utility Week is a large scale expo with conference designed specifically for Asian utilities who seek to transform their utility business model to include digital enablers. It is known as Asia's leader in Advanced Metering Infrastructure (AMI) and features other innovations designed specifically to improve the customer's experience of energy services. The Digital Utility and Customer focused themes are attracting interest from technology innovators from across the world -- both start-ups and established utility leaders. The speaker line-up features over 180 energy technology specialists including: Samuel Tan, Chief Digital Officer, SP Group, Singapore Datuk Seri Azman, CEO, Tenaga Nasional Berhad, Malaysia Dexter Lee, President and Chief Executive Officer, Meralco Energy, Philippines Waiboon Chanchio, CIO, Electricity Generating Authority of Thailand, Thailand Hiroshi Okamoto, Managing Executive Officer, Tokyo Electric Power Company, Japan Song Il-keun, VP, Leader of Energy New Business Lab, Korea Electric Power Research Institute, Korea Hirokazu Yamaguchi, EGM, Global Innovation & Investment, Tokyo Electric Power Company, Japan According to the Event Director, Roderic Mclauchlan: Many utilities see the digital revolution as a threat to their traditional business model, but massive opportunities await those able to transform themselves ahead of the curve. The digital disruptor model is now becoming common in the utility sector and those Asian countries with deregulated energy markets are seeing the rise of the online energy retailer. This is forcing the incumbents to revamp their own digital channel strategies to stay competitive. We also find that social media is having a major impact on customer service strategies as disgruntled customers can effectively vent their frustrations to a large audience. While smart meters are still fairly new to Asia, the business case is now well understood and with the flood of data coming from those meters and the IoT strategies across the enterprise, those utilities with digital models are now reaping the benefits of lower operating costs and improved responsiveness to market change. Asian Utility Week is now free for both energy service companies and vendors to this sector.
