LEGAL MANDATE

  • Section 4 (f)
  • The Authority must …set or approve tariffs and charges

in the manner prescribed by regulation

  • Section 28 (1)
  • The Authority must set as a condition of license the

tariffs to be charged by a licensee in the operation of a petroleum pipeline and approve the tariffs or storage facilities and loading facilities

  • Regulation 5 (2)
  • The provisions of regulations 4(2), 4(3), 4(4), 4(5), 4(6),

4(7) and 4(9) apply, subject to the changes required by the context, to the approval of tariffs for loading and storage facilities

TARIFF APPROACHES

  • Licensee / Applicant

– Selects own methodology to arrive at proposed tariff – Supplies detailed information with tariff application initially – Later completion of Regulatory Reporting should reduce burden

  • The Energy Regulator

– Assesses application against NERSA’s methodology

  • Rate of return determined by WACC
  • Ke calculation by CAPM / any other appropriate model
  • Regulation 4(5)

ALLOWABLE REVENUE

Allowable Revenue = (RAB x WACC) + E + T + D ± C

Where: RAB = Regulatory Asset Base WACC = effective weighted average cost of capital E = maintenance and operating expenses T = notional tax expenses D = Depreciation C = Claw back adjustment (to correct for differences between actual and forecasts in formula elements)

INFORMATION REQUIRED

  • Regulatory Asset base (RAB)
  • Depreciation (D)
  • Operating Expenses (E)
  • Corporate Tax Rate (T)
  • Claw back adjustments (C)
  • Weighted average Cost of Capital (WACC)

REGULATORY ASSET BASE

  • The Regulatory Asset Base (RAB)

RAB = (V – d) + w

  • V = historical cost or “trended original cost”

(TOC) of used and usable property, plant, vehicles and equipment up to the commencement of the tariff period under review

  • d = accumulated depreciation
  • w = net working capital

REGULATORY ASSET BASE The Regulatory Asset Base must be valued using:

“inflation adjusted historical cost” (Regulation 4(6)(e)

Where: WACC = Weighted average cost of capital E = equity Dt = debt Ke = the cost of equity (real) derived from the Capital Asset Pricing Model (CAPM) Kd = the cost of debt (real)

COST OF EQUITY (Ke)

Cost of Equity (Ke) The cost of equity must be determined using the capital asset pricing model and the following formula -

Ke = Risk free rate + (Market Risk Premium + Country Risk Adjustment) * β

  • Market Risk Premium = Market Premium – Risk free rate
  • Country Risk adjustment is for assets outside RSA
  • β = ‘beta’, the systematic risk parameter

(Details in documents)

COST OF DEBT (real)

Expected cost of debt (Kd) The Real Cost of debt is calculated using the following formula:

  • The actual estimated real cost of debt percentage

subject to reasonable tests.

  • The Cost of Debt = (Actual Debt funding the RAB) * (the

real interest rate)

OPERATIONAL EXPENSES

Operational Expenditure (E)

  • Expenses are operating and maintenance
  • expenses. ( categorised in Regulatory

Reporting Manual (RRM) Volume 4. Principles regarding Expenses

  • See write up
slide-13
SLIDE 13

TAXATION

Taxation (T)

  • estimated accounting (corporate) tax

expense for regulated activity

  • Adjustment in next tariff period for
  • ver/under estimation
  • Tax penalties are not allowed.

CLAW BACK

Claw back adjustment = VA + OEA + DCA + GA Where: VA = volume adjustment OEA = Operational Expenditure adjustment DCA = debt cost adjustment GA = general adjustment for any remaining differences between projected Allowable Revenue and actual Allowable Revenue (not resulting from efficiency gains)

Allowable Revenue = (RAB x WACC) + E + T + D ± C Next translate Allowable Revenue into tariffs How?

Tariff issues

  • One part or two part tariff?
  • Notice periods (for storage and discharge
  • f slugs)?
  • Penalties for operator and client if

delivery/discharge times not met?

  • Product quality
  • other
