The Stimson Center’s “Letters from the Mekong” series challenges the assumption that the current rapid pace of dam construction on the Mekong River will continue until the entire river is turned into a series of reservoirs. The construction of even a few large dams risks undermining food security in the world’s most productive freshwater fishery, and dams in China have already sharply reduced the delivery of nutrient-rich sediment needed to the Mekong Delta. However, Stimson’s research strongly suggests that not all of the planned dams will be built. Decreased financing capabilities of foreign investors, drought and climate change, and shifts in regional energy demand indicate reduced profitability and investor interest.

Falling far short of current plans for more than 100 dams on the Mekong mainstream and tributaries will have particular implications for Lao PDR, which has set the export of electricity as its top development priority in its quest to become the “Battery of Southeast Asia.” The lack of a strategic hydropower development plan has created a situation in which Lao PDR is likely to miss its revenue targets while risking severe damage to downstream rice and fish production in Vietnam and Cambodia. Stimson’s most recent report, A Call for Strategic, Basin-wide Energy Planning in Laos, concludes that it is not too late for a new approach that optimizes the tradeoffs among energy, export revenues, and food security, and protects the integrity the Mekong for the benefit of all riparian countries.

A new approach in Lao PDR would maintain the existing focus on exporting electricity to regional markets but also include setting a realistic target of total electricity production from a mix of sources, notably hydropower, solar, and wind. The portfolio mix would be optimized by (1) incorporating sound political, financial, environmental, and social risk analysis into the decision making process; (2) integrating multiple uses of water such as hydropower, transportation, irrigation, and flood control at a basin-wide scale in ways that addresses the needs of downstream countries; and (3) avoid building unnecessary dams in Lao PDR given the associated social and environmental risks.[i] With this strategy in mind, dams with high exposure to financial risk or the greatest environmental impacts would be replaced by alternative projects and, increasingly, efficiency gains from smart infrastructure systems such as effective power grid management.

The Lao government currently lacks the capacity and resources to implement a strategic, basin-wide energy plan because it depends almost entirely on outside developers to build dams under commercial build-own-operate-transfer or BOOT concessions. Its dams are being built in an uncoordinated, project-by-project manner with no prior input from the intergovernmental Mekong River Commission or neighboring countries. As a result, there is at present little opportunity for synergistic planning to optimize the benefits of water use on a basin-wide scale.

Regional Electricity Demand Dynamics

Laos PDR’s economic development plans are almost entirely premised on exporting most of its 24 GW of hydropower potential to neighboring countries. However, regional energy policy shifts call into question whether the anticipated demand for Lao hydropower will materialize. Thailand is currently the primary purchaser of Lao hydropower, but it has a history of overestimating demand. As Thailand refines its energy projections and starts to actively pursue energy efficiency, demand for Lao electricity is likely to drop substantially. Cambodia and Myanmar are potential export markets as both face significant domestic electricity shortages. But energy security concerns are prioritizing the development of domestic sources to avoid future dependency on imports. Myanmar is already developing its large natural gas, hydropower, and solar potential, which is likely to outstrip its domestic needs. Myanmar is likely to become a net power exporter and a competitor to Lao PDR.

Vietnam stands out as possibly the largest future market for electricity from Lao PDR. Vietnam’s electricity consumption is currently growing by 10-12% per year and is projected to grow at 7-10% per year through 2030. In 2015, Vietnam moved from being a net exporter of energy to a net importer as domestic coal demand sky-rocketed.[ii]

Vietnam included this expected growth in its updated Power Development Plan VII, which projects that it will need 130 GW of electricity by 2030.[iii] The updated plan responds to market and climate change pressures by increasing funding for renewable energy and eliminating some proposed coal power plants. But coal will still play a major role, rising from 28% of national power generation in 2014 to more than 50% in 2030.[iv] Furthermore, PDP VII prioritizes meeting demand growth with domestic resources and fails to fully account for regional trade opportunities. Electricity subsidies currently discourage imports of electricity from Lao PDR, but these will be probably phased out as Vietnam runs out of domestic power options.

PDP VII includes 860 MW of power imports from Lao PDR by 2020.[v] This is negligible given Lao PDR’s hydropower potential and the relative affordability of its electricity. Vietnam recently signed an MOU with Lao PDR to buy 5,000 MW of electricity by 2020 but this still represents less than 3% of Vietnam’s electricity demand. [vi] Vietnam could meet its power needs at low financial and environmental cost by substantially increasing its imports of Lao hydropower. Vietnam could thereby take advantage of its role as a major importer to protect its highly productive Mekong Delta from the impacts of upstream dams.

Recently, the global price of solar and wind energy has declined significantly, with the price of solar panels dropping by more than 40% from 2010 to 2014.[vii] Prices will continue to fall, making solar and wind competitive with fossil fuels. Vietnam’s energy prices are estimated to rise to $0.092/kWh by 2020 due to the higher cost of imported coal. This would make both Lao hydropower, which sells for $0.06-$0.07/kWh, and domestic or imported solar, which sells for $0.072/kWh, affordable and cleaner alternatives to coal.[viii]

Expanding both renewables and power exports would help Lao PDR meet two of its six mitigation targets in its Intended Nationally Determined Contribution (INDC) to the UNFCC: Target 2 “To increase the share of renewable energy to 30% of energy consumption by 2025” and Target 5 “To build large-scale (>15 MW) hydropower plants to provide clean electricity to neighbouring countries.”

Making the Case for a Lao National Power Grid

A key component of a Lao hydropower strategy is a national grid that ensures reliable electricity exports to regional markets and meets domestic power needs. Despite building over 30 large dams, Lao PDR’s electricity distribution infrastructure is poor. The main barrier to selling significant amounts of electricity to Vietnam is the lack of a national grid that would allow the country to respond flexibly to demand fluctuations from neighboring countries and avoid a possible excess in hydropower supply. This problem is well understood by the Lao government, which seeks greater flexibility but struggles to predict or maximize revenues from power sales.

Lao PDR’s transmission network is fragmented into largely unconnected sub-grids.[ix] As of 2016, these sub-grids sell and buy power over low voltage connections along sections of its international border. A few 500 kV lines link dams in Lao PDR to major markets in Thailand, and several cross-border 220 kV lines from Thailand transmit electricity to high demand areas in Lao PDR. For Lao PDR to efficiently export electricity, these lines need to be upgraded. Without a national grid, its ability to negotiate favorable export prices is limited.

An ADB study found that with a national grid, Lao PDR could sell power from existing and planned dams on Mekong tributaries and receive export revenue equal to what could be earned from building nine mainstream dams. This would require upgrading older tributary dams and linking them to the national grid, but would give Lao PDR the short-term revenue that it needs without further disruption to the Mekong.[x] A grid would also allow solar and wind projects to feed in and complement hydropower.

The weakness of Lao PDR’s existing patchwork of small grids is why the ADB’s top bilateral investment project is the “Design and Funding of a Background Grid for the Lao PDR.” This would involve “completing the north-south 500 kV line in the Lao PDR, to enable the Lao national grid to transmit power across the country and provide high value-added services from its hydropower plants to neighbors in the Greater Mekong Subregion.” The project summary states that the 500 kV line at a cost of $400 million would allow Lao PDR to more efficiently generate power for both export and domestic consumption, while filling a major gap in the regional power grid.[xi]

Recommendations

Many observers think the door has closed on influencing in Lao hydropower development, but Stimson’s conversations with senior government officials reveal a renewed interest in external engagement on a suite of issues, including power generation optimization, power distribution management, and public participation in dam resettlement. While the space for civil society and non-government engagement is limited, there are new opportunities for government-to-government engagement on hydropower development.

Given the growing recognition within the Lao government of the risks in the current hydropower development trajectory, the time is right to present alternatives that would meet its development needs and support the optimization of the Mekong at the regional scale.

Stimson recommends:

  1. ADB, US, and other donors should fund a feasibility study and design of a national power grid for Lao PDR. A national grid has been an ADB priority for years and it should consider a broader investment to better connect Lao PDR’s sub-grids, improve linkages with neighboring countries, and provide smart grid technology for most efficient deployment of power. This should happen within the next four years so that Lao PDR, Thailand, and Vietnam can adjust energy development plans accordingly.
  2. Vietnam should substantially increase its power purchase agreements with Lao PDR. Vietnam should see this as an opportunity to meet its international climate change commitments and to gain a seat at the table when in deciding which dams get built. Lao hydropower could replace the expensive coal power plants currently in PDP VII. Given that power purchase agreements are a major factor in determining the feasibility of a dam, Vietnam could use these PPAs to ensure that dams that threaten the Mekong Delta are not built.
