Gains from Nepal-India CBET IRADe Study for SARI/EI

South Asia Regional Initiative for Energy Integration(SARI/EI) 28th April, 2016 | Kathmandu, Nepal Integrated Research and Action for Development (IRADe), New Delhi

  • Assess T

echno economic Feasibility of CBET

  • At what price during what period of the year

at what price how much electricity can be traded?

  • i.e. The exporter is willing and able to export

and the importer is willing and able to import

  • What are the economic gains to NEPAL of

such trade taking in to account earnings from export and its macro-economic impact on the economy

The Objective

slide-3
SLIDE 3
  • Power sector development strategies from 2012 to 2047
  • TIMES MARKAL Model solved for every 5th year

simultaneously

  • Detailed TIMES-MARKAL model with 288 time-periods

per year

  • For each time slice demand must equal supply
  • TIMES-MARKAL model for each country has detailed

plant wise data and options of different types of new plants

  • Solution minimizes cost to meet specified demand and

provides optimal solution and trade levels and prices for each 288 time-periods for all the years

Approach

slide-4
SLIDE 4
  • However, trade will affect economic development

and level of demand particularly true for NEPAL

  • A macro-economic SAM based model covers the

whole economy balances supply and demand for each sector, also investment and savings, balance of payment for each year, etc.

  • So earnings from electricity export increases

availability of resources for investment

  • Higher Growth leads to higher domestic demand for

electricity

  • Iterate between the two models to get economically

viable and technically feasible scenarios.

Nepal Load Duration Curve Assumption

Single day Peak load curve was available from various NEA Annual Reports:

  • 28 January 2011
  • 13 January 2012
  • 13 November 2012
  • 03 Nov 2013

28 January 2011 13 November 2012 03 Nov 2013 13 January 2012

These various load curves were used for interpolating a continuous load curve for the year 2011-12 using hourly growth rates.

Key Findings  Electricity Trade between Nepal and India supports early development of Nepal's untapped hydro potential  Development of Storage based hydro capacities is important to add generation flexibility in the grid  Development of PROR is also important as they provided generation flexibility with a day  Nepal remains Net exporter from 2017 onwards however it will still needs to import electricity during certain time periods of a day

Economic Benefits of Power Trade- An Economic Model based Analysis For Nepal

Model Results are for Discussion Purpose Only

slide-36
SLIDE 36

 The model is a Linear Programming optimisation model based on a activity analysis framework  Model maximises the sum of discounted value of the stream of consumption values over a time period of 50 years subject to a set of constraints – Macro-economic relationships, – technological feasibilities and potentials and – monotonicity constraints  The economic relationships between sectors are modelled based on the Social Accounting (SAM) of 2007-08 for Nepal.  The model is solved simultaneously for all years from 2007-2050  The model incorporates changing demand pattern with changing incomes  The income distribution is endogenously determined

Supply Side of the Economy

  • The 57 × 57 sector SAM is aggregated to 6 × 6 sector SAM and included

in the Model.

  • The sectors considered in the SAM are

– Agriculture : – Manufacturing: – Electricity – Gas & Water supply – Transport – Other Services

  • The Electricity sector is disaggregated into 8 sectors of which 6 are

Hydro power generation technologies.

  • The availability of goods in the economy is obtained either through

domestic production or imports from outside.

  • Imports of goods and services in the economy are constrained to grow

within bounds that are specified as ratios of Availability (Production + imports)

slide-42
SLIDE 42
  • The power generation technologies Considered in the

model are – Hydro –ROR – Hydro-PROR – Hydro-Storage – Hydro-ROR with external funding – Hydro-PROR with external funding – Hydro-Storage with external funding – Solar – Diesel

Electricity Sector

slide-43
SLIDE 43
  • Demand in the Economy is composed of

– Private household consumer demand – Government consumption demand – Intermediate demand – Investment demand – Export demand

  • The model maximizes the private household consumption.
  • Government consumption is exogenously specified in the model.
  • Intermediate demand in each sector is obtained as a function of

production levels using the IO coefficients from the SAM.

  • Exports are specified to grow within upper/lower bounds that are

specified as ratios of domestic production.

  • Investment demand is obtained through a set of behavioural equations

and macro economic identities

Demand Side of the Economy

slide-44
SLIDE 44

Household Consumer demand

  • The household sector is divided in to 10 expenditure

classes each in rural and urban areas

  • The different tastes and preferences of each

household group is represented by its own demand parameter.

  • Each household’s demand preferences are represented

by separate Linear expenditure system parameters

  • Household class wise per capita expenditure and

population Proportions is endogenously determined by separate log normal distributions for Rural and Urban areas

  • People from a lower income group shift to a higher

income group with higher levels of per capita consumption.

slide-45

  • Investments, Savings and capital formation

is determined through a optimising behaviour based on a set of behavioural macro economic relations

  • The trade sector is endogenous to the

model

  • Trade variables like exports and imports are

constrained to grow within bounds and also satisfy balance of payment constraint

  • Net capital inflow is endogenous and a

positive but falling function of GDP.

  • Sectoral output at any time point is

constrained by the capacity to produce given the capital stock in that sector in that time.

  • The electricity output from Hydro technologies

is constrained by the maximum possible potential.

  • Bounds are imposed on the maximum possible

investment increase in each electricity sector.

  • The model is a macro model covers the whole

economy

  • Bottom up – top down model
  • Multi sectoral inter temporal optimization model
  • 6 commodities – more can be added
  • 13 activities – new activities can be included
  • Endogenous GDP

, production, consumption, Investment and demand.

  • Endogenous income distribution – 20 expenditure

classes (10 rural & 10 urban)

SALIENT FEATURES OF THE MODEL

  • Specific technologies can be assessed.
  • Feedback / rebound effect captured.
  • Optimal strategy to reach a goal/ target.
  • Inter sectoral consistency.
  • Can asses impacts on poor.
  • Investment/ Consumption / Capacity consistency.
  • Welfare impacts of various policies.
  • Can be extended to be a CGE model

Scenarios

  • Base scenario: marginal savings rate is assumed at

15% compared to 8% in SAM.

  • No Trade : Electricity Exports are assumed to be

zero and imports zero after 2011-12. Electricity generation profile same as in the TIMES-MARKAL model.

– To reflect the ambition in NEA and Nepal’s Plans

the marginal savings rate raised to 25% compared to 15%

  • Trade scenario: Electricity exports, Imports and

technology wise production same as TIMES-MARKAL, the ratio of export price to domestic price from the TIMES-MARKAL model assumed in the SAM Model

Marginal savings rate 25%

Findings

 Per capita Electricity demand increases to 3808 kwh/person in the Trade scenario compared to 2556 kwh/person in the No trade scenario and 1095 kwh/person in the Base scenario. The increase in power demand is nearly 3 times as compared to the base scenario  The economic gains are much more substantial if one considers the base scenario  Per Capita GDP doubles in the Trade scenario as compared to Base scenario
