Heroes' Day commemoration to be held on 19 May - The Island
The widespread torrential rains currently experienced countrywide are expected to provide significant financial relief to the debt-ridden Ceylon Electricity Board (CEB) by sharply increasing hydroelectric power generation and reducing dependence on costly thermal and coal-powered electricity generation, power sector officials said yesterday. Senior engineers of the CEB told The Island the rapid rise in water levels in major catchment areas and reservoirs had already strengthened hydropower generation capacity across the country. Officials of the Irrigation Department confirmed that 33 reservoirs are presently spilling following continuous heavy rainfall over several parts of the island. Among the major reservoirs spilling are Rajanganaya, Lunugamwehera, Weheragala, Deduru Oya, Nalanda and Wemedilla reservoirs, while several spill gates have been opened to release excess water due to heavy inflows into the catchment systems. An Irrigation Department engineer said catchment areas linked to the Mahaweli, Kala Oya and southern river basins had received exceptionally heavy rainfall over the past several days. “The inflows are extremely high. Reservoir capacities are increasing rapidly and this is highly beneficial for irrigation, water supply and hydroelectric generation,” the official said. CEB engineers explained that the increase in reservoir storage levels would enable the Board to maximise hydroelectricity generation from major hydropower stations linked to the Mahaweli and Laxapana systems. A senior CEB engineer said hydropower remained the cheapest electricity source available to Sri Lanka. “Hydro generation costs are minimal compared to thermal generation. Once reservoirs fill up, we can considerably reduce expensive oil-based thermal generation,” the engineer said. According to power sector estimates, hydroelectricity generation costs remain below Rs. 5 per unit, whereas coal-fired electricity generation costs range between approximately Rs. 18 and Rs. 25 per unit depending on international coal prices and exchange rate fluctuations. Diesel and furnace oil-powered thermal generation are significantly more expensive, costing between Rs. 40 and Rs. 70 per unit. CEB officials said the prevailing rainy conditions were therefore producing enormous savings for the financially-strained utility. Daily electricity demand currently fluctuates between 45 million and 50 million units. One unit equal 1 kWh. One million units 1 GWh. Energy sector estimates indicate ...
Memorial Day (Monday, May 25th, 2026) - wikidates.org
Memorial Day is an American holiday celebrated on the last Monday of May aim to honor people who passed away while serving in the U.S. military. Memorial Day on May 30th recalls burgers, hot dogs, swimming pools, and summer for many Americans. But the last Monday in May is, most importantly, a time to honor those who died fighting in the United States Armed Forces. It was a vacation steeped in American history and tradition. The day actually began as Memorial Day. After the Civil War, mourners laid flowers on the graves of Union and Confederate soldiers to show their gratitude. Memorial Day has also arrived to signal the "unofficial" start of summer, but let's remember the heroes who made it. History of Memorial Day In the spring of 1865, the Civil War ended when Robert E. Lee surrendered the major Confederate army at Appomattox Court House on April 9th. More than 620,000 soldiers died in the conflict that stroke lasted 4 years. General John A. Logan of the Grand Army of the Republic (an organization of Confederate veterans) would eventually choose May 30th, 1868 as the date to honor the fallen: May 30th, 1868 was dedicated to spread flowers or decorate the graves of comrades who died to defend their homeland during the last rebellion. At present, their bodies are located in most of the cities, villages, and hamlet churches on the land… Logan apparently chose May 30th because flowers would bloom all over the country. In the late 19th century, Memorial Day ceremonies were held on May 30th across the country. States have adopted declarations, and the Army and Navy have adopted rules for proper compliance at their facilities. The crowd for the first Memorial Day service at Arlington National Cemetery was roughly the size of those attending today's celebrations about 5,000 people. Small American flags were planted on each grave - a tradition that is continued in many national cemeteries today. In recent years, the custom of decorating the graves of deceased loved ones has become popular in many families. By 1890, each Northern state had brought Memorial Day become an official holiday. However, this was not the case in the South, where states continued to honor their dead on separate days until after World War I. May 30th is celebrated for decades. However, in 1968, after the Uniform Monday Holiday Act was passed, Memorial Day was celebrated on the last Monday in May to create a three-day weekend for federal employees. The change came in 1971. At last, ...
