Sri Lanka may not be able to supply 50Hz power if Victoria, Kotmale dry up

PARCHED: Hydro reservoirs are down and the bottom is exposed.

ECONOMYNEXT – Sri Lanka’s Ceylon Electricity Board could lose the ability to provide a stable 50 cycle frequency as two large hydro plants are running dry, which can lead to outages or damage to customer equipment, industry analysts warn.

The CEB has asked for sustained power cuts to conserve water for the dry season in February and March after a coal plant outage could not be filled with other thermal plants due to forex shortages.

A power grid supplying alternative current operates on a cycles where the current switches from negative to positive.

Sri Lanka’s power grid operates on a 50 cycles per second (Hz).

When demand rises from customers the CEB has to ramp up generation to avoid the frequency falling below 50Hz and reduce generation when demand falls to stop the frequency going above 50 Hz.

If it is not done, power supply will become unstable and customer equipment will be damaged. Sections of the grid can also fail.

This is why the CEB has to shed loads despite political or regulatory orders making power cuts ‘illegal’.

In most countries that changing demand and supply or frequency response is managed by a key power station.

In Sri Lanka frequency response is provided by Kotmale and Victoria power stations. Unlike thermal stations which run at maximum efficiency within narrow ranges, large hydros can vary their output widely.

The CEB uses either Kotmale or Victoria for the purpose.

However with the failure of a coal plant and the inability to get foreign exchange due to money printing, the CEB has been forced to run down Victoria and Kotmale to avoid power cuts.

CEB has sought to cut power for one hour cuts to conserve water. Earlier the PUCSL gave permission to cut power but the focus was on the short term consideration of available capacity.

“This is not a problem of day-to-day capacity availability,” an industry official said. “There are other implications which have knock on effects. That is why the load shedding was sought.”

Kotmale generation is expected to be halted to conserve water for irrigation after the Maha season ends.

Only Victoria is expected to be available for frequency control from mid March.

The CEB is rapidly running down its water storage which is already down to below 50 percent industry officials said.

Long power cuts of 3 to 4 hours may be forced on the only by late March unless loads are shed industry officials have warned.

Energy Minister Udaya Gammanpila has made similar warnings.

The rapid fall in storage is identical to 2019, which was a power cut year according to industry watchers.

The CEB runs its generators giving priority to drinking water, irrigation and then for its own use.

In Kelani River Castlereigh and Moussakelle, which are used to provide water to Colombo during the March – April dry season are expected to fall below operating level by February and March, depriving Colombo of water.

In another complication, Samanalawewa which is crucial to providing power to the Southern grid is also running down. The Southern grid which is in a 132kV section of the grid has limited generators.

Unless water is conserved large sections of the grid may face outages, industry watchers say. (Colombo/Feb14/2022)

Sri Lanka may have to depend on India or nuclear to reach low carbon target: researcher

DOUBLE WHAMMY: In Sri Lanka’s driest period, wind potential also goes down, a researcher and policy advocate says

ECONOMYNEXT – Sri Lanka will need to either connect to India or set up a nuclear power plant if the country is to reach its renewable energy targets due the country’s weather patterns, a researcher and policy advocate has said.

Sri Lanka has set ambitious goals for renewable electricity generation by 2030, apparently without much prior study or any costs being revealed when the target was set by President Gotabaya Rajapaksa.

Rohan Pethiyagoda, a taxonomist and researcher who had also been senior state officials involved in policy at one time said overall Sri Lanka used a large volume of biomass (firewood) for cooking.

“We need to recognize, of course, that about 60 percent of Sri Lankan households still use firewood as their primary fuel,” Pethiyagoda told a climate forum organized by Sri Lanka’s Ceylon Chamber of Commerce.

“Bless them, because they reduce our dependence on fossil fuels for cooking. Even the tea industry, one of our largest exports, uses biomass as its primary fuel for about 90 percent of its production.”

In the electricity sector, where the renewable lobby and other activists oppose coal on the basis of carbon emissions based on international trends, as well as dust, base load still has to be generated if thermal generators are replaced.

Solar power is available only for a few hours in daytime and it can also vary depending on cloud cover.

Hydro power (run of the river plants) is more stable but is dependent on rain. Large hydros with storage can be used for peaks, industry analysts say.

Wind is available throughout the day but can also be unstable. The problem of variability (non-firm energy) can be solved to some extent through ramping and battery storage at additional cost, analysts say.

A renewable plant in Poonakary with battery storage was priced at around 48 to 49 rupees (about 15 US cents) based on public statements.

Meanwhile Pethiyagoda said Sri Lanka’s weather patterns created an additional problem.

“We have this unusual thing for our renewable energy in Sri Lanka, that at the tail end of the northeast monsoon, from about December to April, we have a dry period in this country, which means that our hydro potential during those months goes down,” Pethiyagoda said.

“Now, as luck would have it, our wind potential goes down at the same time.”

As a result, Sri Lanka needs a reliable alternative to the current coal baseload.

“So for that reason especially, we need to look at either connecting to India’s grid in the long term or having a nuclear facility in Sri Lanka if we want to be low carbon. And of course, we need to replace our vehicle fleet.”

“And our base load can probably come from nuclear,” Pethiyagoda said.

“But whichever way we do it, the cheaper way would be for us to connect to India’s grid.

“Whichever way we do it, we’re looking at an investment of about 40 billion dollars. And then we have the problem of looking at how wind and solar will behave.”

It was not clear what the 40 billion dollar investments would be made up of.

Sri Lanka’s external debt as at December 2024, including unpaid principal after default was 37.3 billion US dollars.

In 2021 when the 70 percent target was unveiled in President Gotabaya Rajapaksa’s election manifesto power engineers said a 53 percent energy share planned for 2030 in a general plan at the time was was equal to that of Germany.

Pushing up the share to 70 percent would require billions of dollars of extra investments, they said.

Sri Lanka’s CEB March 2024 profits Rs84bn with capital gain, fx strength

ECONOMYNEXT – Sri Lanka’s state-run Ceylon Electricity Board group has reported profits of 86 billion rupees with the help of 25.9 billion rupees of capital gains from a transfer of shares, interim accounts show.

The rupee also appreciated in the quarter which keeps imported fuel prices low.

As a standalone entity, the Ceylon Electricity Board, made profits of 84.6 billion rupees in the March quarter.

CEB’s revenues rose 38.5 percent to 167 billion rupees in the March 2024 quarter, while cost of sales fell 26.1 percent to 105.0 billion rupees giving gross profits of 62.7 billion rupees.

The CEB also reported 30.6 billion rupees of other incomes and gains in the March quarter, up from 3.1 billion rupees last year.

Other Income and Gains

The utility said it made a 25.9 billion rupee capital gain from transferring LTL Holdings shares to West Coast Power an IPP in which other entities have a majority holding.

In the quarter the rupee also appreciated.

A rupee appreciation will help reduce the carrying cost of dollar loans and also reduce the cost of imported thermal fuels and maintenance costs of spares.

The central bank allowed Sri Lanka’s exchange rate to appreciate from 324.40 rupees in December 2023 to 300.17 on March 2024 amid deflationary policy and weak private credit allowing imported fuel costs also to fall.

Especially after 1978, after rate cuts drove the country into balance of payments crises, the central bank had collected reserves with free market interest rates, but has not usually allowed the exchange rate to re-appreciate despite generating a BOP surplus with deflationary policy.

Un-anchored Bad Money

Before 1978, when an apparently doctrinally foxed International Monetary Fund abandoned both external and specie anchors simultaneously after the Fed closed its gold window triggering the Great Inflation period, Sri Lanka also did not depreciate its currency, analysts have pointed out.

Since it was set up in 1951, the central bank has printed money under various dual anchor conflicting Saltwater-Cambridge ideologies (re-financing rural credit, sterilizing outflows, potential output targeting, yield curve targeting) to create forex shortages and currency crises and started to go the IMF from the mid-1960s.

From 1978, after the IMF’s second amendment to its Articles denied the central bank a credible external and domestic anchor simultaneously, the currency stated to depreciate steeply.

The government was therefore unable to balance its budget and state enterprises were also unable to balance their budgets running large losses whenever the rupee fell and energy prices went up.

After abandoning its external and specie anchor the central bank followed a anchor conflicting regime involving money supply targeting without a floating exchange rate in the 1980s.

The ideology was rejected in toto by Singapore, Malaysia, Hong Kong, Thailand and China.

Since the end of a civil war macro-economists have followed inflation targeting without a floating exchange combined with extreme macro-economic policy to target potential output, eventually driving the country into external default.

Budgets went haywire in the early 1980s as the rupee fell, despite then President JR Jayawardene cutting subsidies and ending price controls (administered prices) two years earlier, in reforms that Singapore’s economic architect and one-time Finance Minister Goh Keng Swee said were “economic reforms which most people had considered politically impossible.”

Goh who set up a currency board in Singapore rejecting Cambridge-Saltwater ideology, warned JR not to destroy the rupee.

“Exchange rate policies involve many complicated technical issues which I do want to discuss here,” he said.

“On balance, the disadvantage of a depreciating rupee will, I believe, outweigh the advantages. Most of the products whose prices are administered are ether wholly imported or contain a high import content. About a quarter of rice consumption is imported.

“All wheat from which four and bread are produced is imported. The same holds true of kerosene and milk powder.

“Bus fares ware largely determined by the rupee price of imported oil and spare parts. Fertilizers are also mostly imported.”

At the time Sri Lanka had hydro-electricity.

Capital Injections

Some of the CEB’s dollar loans were been taken over by the central government after the steepest currency collapse in the history of the central bank in 2022 and external default.

The CEB’s contributed capital as at end March 2024 was 991.4 billion rupees up from 865.1 billion rupees.

With the March quarter profits with some financial engineering involving the asset sale and the government equity injection, the CEB’s group accumulated losses reduced to 456 billion rupees from 575 billion rupees.

The CEB ran large losses as the regulator failed to raise tariffs as macro-economists printed money to target potential output over the past decade.

From 2011 to 2022 the rupee fell from 113 to 370 to the US dollars as the central bank ran un-anchored monetary policy the regulator only raised prices in 2022.

Energy Minister Kanchana Wijesekera said the last price cut was also made possible due to rupee appreciation.

With no potential output targeting (no inflationary open market operations), the country has started to recover from the stability that has been provided up to now amid weak private investment credit.

Sri Lanka’s private credit is now starting to recover.

Based on past trends of using statistics instead of classical economic principles (cutting current current interest rates with inflationary open market operations of a money monopoly based on historical inflation rates under ‘data driven monetary policy’ without regard to domestic credit) analysts have warned of a return to monetary instability under potential output targeting.
