4 Indian Wind Power Dec. 2019 - Jan. 2020
1.	 Introduction
Forecasting and Scheduling (F&S) of solar and wind power
generation is required to manage the grid network for maximum
utilization of renewable energy. Hence the concept of forecasting
and scheduling (F&S) of renewable energy generators and the
commercial settlement was introduced in Indian context by
CERC through Indian Electricity Grid Code (IEGC), 20101 and
the Renewable Regulatory Fund mechanism2. Due to several
implementation issues, the mechanism was never made
operational. To formulate an implementable framework, CERC
also issued 2nd amendment to regulation for the Deviation
Settlement Mechanism (DSM) and other related matters3.
After CERC regulation, Forum of Regulators (FOR)4 and other
state regulators issued or drafted regulation related to the
forecasting and scheduling of wind and solar power generation.
Unlike DSM penalty of intrastate forecasting and scheduling of
wind and solar power generation, the ‘actual penalty’ and the
‘DSM penalty’ of wind and solar power generation in interstate
CERC regulation are different. This article briefly focuses on
the theoretical and evidence based understanding of ‘Actual
Penalty’ and ‘DSM Penalty’ in case of interstate regulation.
2.	 Theoretical Framework
In interstate regulation, the payment is on schedule generation,
unlike the intrastate in which the payment is on actual
generation. Hence, to calculate the actual penalty due F&S in
case of interstate regulation, we can state that,
Actual Penalty =
(Schedule Generation × PPA rate + DSM Penalty) -
Actual Generation × PPA rate	 (1)
Here DSM penalty is negative when payable to the pool by
the generators and positive when payable by the pool to the
RE generators. By simple algebraic manipulation (1) can be
written as,
Actual Penalty =
DSM Penalty - (Actual Generation - Schedule generation) ×
PPA rate	 (2)

Which transforms into,
Actual Penalty (P) =
DSM Penalty (∆) - Energy Deviation (δ) × PPA rate (p)	 (3)
i.e. P = ∆ - δp	(4)
Here (4) can be viewed as the fundamental equation to
calculate the actual penalty in interstate F&S regulation. Since
(4) is true for each of the time-block, for all time-blocks we
can state that,
∑P = ∑∆ - p∑δ
If we replace, ∑P as P, ∑∆ as ∆ and ∑δ as δ, (4) remains
same, and the total actual penalty (monthly or weekly) can be
calculated from the total DSM (monthly or weekly) and total
energy deviation (monthly or weekly). Interestingly, total DSM
and total energy deviation value (monthly or weekly) is readily
available at ERC sites, and the actual penalty can be calculated
if the PPA rate (p) is known.
Hence (4) can be viewed as a fundamental equation to
calculate the actual penalty in interstate regulation.
Since P = ∆ - δp , it is easy to state that the actual penalty due
to the deviation (P) is not the DSM penalty (∆).
Since the actual penalty (P) is always payable, it is always
negative. Hence DSM penalty (∆) and energy deviation (δ) are
of same sign, as shown in Table I.

(a) (b)
Figure 1: Shows the percentage of energy deviation vs (a) DSM penalty per unit capacity and
(b) Actual penalty per unit capacity as per the Interstate regulation using the equation in Table II.
Figure 2(a) shows the energy deviation (MW-Hr) vs (a)Weekly DSM Penalty and 2(b) Weekly Actual Penalty for
7 different generators at SRPC. The bold black curve in 2(b) shows the average trend line.
Since different RE generators are of different capacities, to
normalize the calculation, let divide (4) by the available capacity
(AvC), i.e.
= −
Where is the penalty per unit capacity, is DSM per unit
capacity and represents the percentage in energy deviation.
Hence, as per interstate F&S regulation, the equation relating
‘DSM penalty’ and ‘percentage in energy deviation’ can be
represented as Table II.
3.	 Results and Discussion
Using the equation in Table II, the percentage of energy
deviation vs DSM penalty per unit capacity for different PPA
rate (p) can be shown as Figure 1(a). As shown in figure
1(a), when the energy deviation is positive (negative), the
DSM penalty is positive (negative). It is interesting to see that
the curve representing DSM penalty vs. energy deviation is
continuous, though the function seems to be an odd function
(f(-x) = - f(x)), the curve is not an odd function, i.e. for same
energy deviation in the positive and negative direction the DSM
penalty for under-schedule and over-schedule are not same
( f (-δ) ≠ -f (δ) ).
8 Indian Wind Power Dec. 2019 - Jan. 2020
The Actual Penalty vs energy deviation is shown in figure 1(b)
for different values of PPA rate (p). Here it is interesting to see
that the curve is symmetric about the y-axis and it is an even
function (f(-x) = f(x)). Hence, for same energy deviation in the
positive and negative direction the Actual penalty for under-
schedule and over-schedule are same (f(-δ) = f(δ)). Hence,
as per interstate regulation, if the forecast is over-scheduled or
under-scheduled, the actual penalty remains same for same
energy deviation in positive or negative direction.
The theoretical structure of ‘Actual Penalty’ and ‘DSM Penalty’ is
validated by evidence based data of 7 different RE generators
of the Southern Regional Power Committee (SRPC) website5
where DSM data and energy deviation data are openly available.
As shown in figure 2(a), the DSM penalty data vs energy
deviation data has close match with the curve in figure 1(a).
Though it is expected that the actual penalty value in figure
2(b) will closely match the nature of curve in figure 1(b), the
‘actual penalty’ in figure 2(b) is very scattered due to the high
value of the penalty due to erroneous forecast. From Figure 2
(a) and (b), we can state that the tendency of over-schedule
the forecast is very high, though it is evident from Figure 1(b)
that the actual penalty for under-schedule and over-schedule is
same for the same amount of energy deviation.
4.	 Conclusion
This article shows a simple method of calculation the ‘actual
penalty’ as per DSM in the case of interstate regulation since

	º Renewables Need to Double by 2030 to Reach Climate Goals – IRENA
The share of renewables in the global energy mix should more than double by 2030 to advance the global energy
transformation, achieve sustainable development goals and a pathway to climate safety, according to the International
Renewable Energy Agency (IRENA). Renewable electricity should supply 57% of the global power by the end of the
decade, up from 26% today. The Agency’s data shows that annual renewable energy investment needs to double from
around $330 billion today to close to $750 billion to deploy renewable energy at the speed required. Much of the
needed investment can be met by redirecting planned fossil fuel investment. Close to $10 trillion of non-renewables
related energy investments are planned to 2030, risking stranded assets and increasing the likelihood of exceeding the
world’s 1.5 degree carbon budget this decade.

	º Electricity Act May Be Amended To Ensure Discoms Honour Power Pacts
The government is planning to introduce a bill to amend the Electricity Act to prevent states from reneging on power
pacts, particularly renewable energy contracts, and distribution companies from defaulting on bills. It wants to ensure
that renewable energy tariffs are not changed after execution of contracts, and electricity regulatory commissions have
more teeth to enforce power purchase agreements between projects and distribution companies (discom), a senior
government official said. The proposal comes after the new governments in Andhra Pradesh and Maharashtra refused
to honour power purchase agreements, leaving investors jittery.
Source: ET Bureau, January 17, 2020
the DSM penalty and ‘Actual Penalty’ are not same in case of
interstate regulation unlike to intrastate. The P = ∆ - δp rule is an
easy way to compute the actual penalty value since and values
are easily available at weekly or monthly bill of DSM settlement.
The article shows the theoretical structure for energy deviation
vs Actual Penalty curve from which we can state that the actual
penalty for under-schedule and over-schedule are same for the
same amount of energy deviation.

Actual Penalty and Deviation Settlement Mechanism (DSM) Penalty in Interstate F&S Regulation for RE Generators

  • 1. 4 Indian Wind Power Dec. 2019 - Jan. 2020 1. Introduction Forecasting and Scheduling (F&S) of solar and wind power generation is required to manage the grid network for maximum utilization of renewable energy. Hence the concept of forecasting and scheduling (F&S) of renewable energy generators and the commercial settlement was introduced in Indian context by CERC through Indian Electricity Grid Code (IEGC), 20101 and the Renewable Regulatory Fund mechanism2. Due to several implementation issues, the mechanism was never made operational. To formulate an implementable framework, CERC also issued 2nd amendment to regulation for the Deviation Settlement Mechanism (DSM) and other related matters3. After CERC regulation, Forum of Regulators (FOR)4 and other state regulators issued or drafted regulation related to the forecasting and scheduling of wind and solar power generation. Unlike DSM penalty of intrastate forecasting and scheduling of wind and solar power generation, the ‘actual penalty’ and the ‘DSM penalty’ of wind and solar power generation in interstate CERC regulation are different. This article briefly focuses on the theoretical and evidence based understanding of ‘Actual Penalty’ and ‘DSM Penalty’ in case of interstate regulation. 2. Theoretical Framework In interstate regulation, the payment is on schedule generation, unlike the intrastate in which the payment is on actual generation. Hence, to calculate the actual penalty due F&S in case of interstate regulation, we can state that, Actual Penalty = (Schedule Generation × PPA rate + DSM Penalty) - Actual Generation × PPA rate (1) Here DSM penalty is negative when payable to the pool by the generators and positive when payable by the pool to the RE generators. By simple algebraic manipulation (1) can be written as, Actual Penalty = DSM Penalty - (Actual Generation - Schedule generation) × PPA rate (2) Actual Penalty and Deviation Settlement Mechanism (DSM) Penalty in Interstate F&S Regulation for RE Generators Abhik Kumar Das Technical Director del2infinity Energy Consulting contact@del2infinity.xyz Sandeep Suman Assistant Manager (E&M) Coal India Limited Which transforms into, Actual Penalty (P) = DSM Penalty (∆) - Energy Deviation (δ) × PPA rate (p) (3) i.e. P = ∆ - δp (4) Here (4) can be viewed as the fundamental equation to calculate the actual penalty in interstate F&S regulation. Since (4) is true for each of the time-block, for all time-blocks we can state that, ∑P = ∑∆ - p∑δ If we replace, ∑P as P, ∑∆ as ∆ and ∑δ as δ, (4) remains same, and the total actual penalty (monthly or weekly) can be calculated from the total DSM (monthly or weekly) and total energy deviation (monthly or weekly). Interestingly, total DSM and total energy deviation value (monthly or weekly) is readily available at ERC sites, and the actual penalty can be calculated if the PPA rate (p) is known. Hence (4) can be viewed as a fundamental equation to calculate the actual penalty in interstate regulation. Since P = ∆ - δp , it is easy to state that the actual penalty due to the deviation (P) is not the DSM penalty (∆). Since the actual penalty (P) is always payable, it is always negative. Hence DSM penalty (∆) and energy deviation (δ) are of same sign, as shown in Table I. Table I: DSM Penalty vs Energy Deviation DSM penalty (∆) Energy deviation (δ) Comment + DSM Receivable + Actual > Schedule Under-schedule / Over-injection - DSM Payable - Actual < Schedule Over-schedule / Under- injection

  • 4. 7Indian Wind PowerDec. 2019 - Jan. 2020 (a) (b) Figure 1: Shows the percentage of energy deviation vs (a) DSM penalty per unit capacity and (b) Actual penalty per unit capacity as per the Interstate regulation using the equation in Table II. Figure 2(a) shows the energy deviation (MW-Hr) vs (a)Weekly DSM Penalty and 2(b) Weekly Actual Penalty for 7 different generators at SRPC. The bold black curve in 2(b) shows the average trend line. Since different RE generators are of different capacities, to normalize the calculation, let divide (4) by the available capacity (AvC), i.e. = − Where is the penalty per unit capacity, is DSM per unit capacity and represents the percentage in energy deviation. Hence, as per interstate F&S regulation, the equation relating ‘DSM penalty’ and ‘percentage in energy deviation’ can be represented as Table II. 3. Results and Discussion Using the equation in Table II, the percentage of energy deviation vs DSM penalty per unit capacity for different PPA rate (p) can be shown as Figure 1(a). As shown in figure 1(a), when the energy deviation is positive (negative), the DSM penalty is positive (negative). It is interesting to see that the curve representing DSM penalty vs. energy deviation is continuous, though the function seems to be an odd function (f(-x) = - f(x)), the curve is not an odd function, i.e. for same energy deviation in the positive and negative direction the DSM penalty for under-schedule and over-schedule are not same ( f (-δ) ≠ -f (δ) ).
  • 5. 8 Indian Wind Power Dec. 2019 - Jan. 2020 The Actual Penalty vs energy deviation is shown in figure 1(b) for different values of PPA rate (p). Here it is interesting to see that the curve is symmetric about the y-axis and it is an even function (f(-x) = f(x)). Hence, for same energy deviation in the positive and negative direction the Actual penalty for under- schedule and over-schedule are same (f(-δ) = f(δ)). Hence, as per interstate regulation, if the forecast is over-scheduled or under-scheduled, the actual penalty remains same for same energy deviation in positive or negative direction. The theoretical structure of ‘Actual Penalty’ and ‘DSM Penalty’ is validated by evidence based data of 7 different RE generators of the Southern Regional Power Committee (SRPC) website5 where DSM data and energy deviation data are openly available. As shown in figure 2(a), the DSM penalty data vs energy deviation data has close match with the curve in figure 1(a). Though it is expected that the actual penalty value in figure 2(b) will closely match the nature of curve in figure 1(b), the ‘actual penalty’ in figure 2(b) is very scattered due to the high value of the penalty due to erroneous forecast. From Figure 2 (a) and (b), we can state that the tendency of over-schedule the forecast is very high, though it is evident from Figure 1(b) that the actual penalty for under-schedule and over-schedule is same for the same amount of energy deviation. 4. Conclusion This article shows a simple method of calculation the ‘actual penalty’ as per DSM in the case of interstate regulation since SnippetsonWindPower º Renewables Need to Double by 2030 to Reach Climate Goals – IRENA The share of renewables in the global energy mix should more than double by 2030 to advance the global energy transformation, achieve sustainable development goals and a pathway to climate safety, according to the International Renewable Energy Agency (IRENA). Renewable electricity should supply 57% of the global power by the end of the decade, up from 26% today. The Agency’s data shows that annual renewable energy investment needs to double from around $330 billion today to close to $750 billion to deploy renewable energy at the speed required. Much of the needed investment can be met by redirecting planned fossil fuel investment. Close to $10 trillion of non-renewables related energy investments are planned to 2030, risking stranded assets and increasing the likelihood of exceeding the world’s 1.5 degree carbon budget this decade. Source: Smart Energy International, Jan 13, 2020 º Electricity Act May Be Amended To Ensure Discoms Honour Power Pacts The government is planning to introduce a bill to amend the Electricity Act to prevent states from reneging on power pacts, particularly renewable energy contracts, and distribution companies from defaulting on bills. It wants to ensure that renewable energy tariffs are not changed after execution of contracts, and electricity regulatory commissions have more teeth to enforce power purchase agreements between projects and distribution companies (discom), a senior government official said. The proposal comes after the new governments in Andhra Pradesh and Maharashtra refused to honour power purchase agreements, leaving investors jittery. Source: ET Bureau, January 17, 2020 the DSM penalty and ‘Actual Penalty’ are not same in case of interstate regulation unlike to intrastate. The P = ∆ - δp rule is an easy way to compute the actual penalty value since and values are easily available at weekly or monthly bill of DSM settlement. The article shows the theoretical structure for energy deviation vs Actual Penalty curve from which we can state that the actual penalty for under-schedule and over-schedule are same for the same amount of energy deviation.
