Our Services
We can provide advice and support in the following areas:
Settlement Statement, Tariffs, Volumes and Losses.
Billing System.
Regulatory Monitoring and Support.
PPA Administration and GSA Administration.
Financial Modelling and Planning.
Board Advisory, Ad Hoc Support and Horizon Watch.
Training and Capacity Building.
Settlement Statement; Tariffs, Volumes and Losses
The Market Operator, ONEM has been issuing Preliminary Settlement Statements around the
9th of each month and final statements around the 20th. The statements have been
characterised by use of rates different to those expected by Sellers and by calculations that
are not consistent with the Interim Rules and NERC orders.
We can review each statement for consistency with the Interim Rules, the Market Rules, the
MYTO Order, the MYTO Model, PPA’s and the ‘Existing Arrangements’1. We can highlight
errors and inconsistencies and prepare a statement of dispute for the Client to submit to the
MO and NERC.
Billing System
Genco revenue will be billed through the Market Operator for all generation costs, under the
PPA and the regulated tariffs under the MYTO II. This is built up from declarations of capacity
hour by hour through the month and hour by hour Availability and Despatch. The work
involved to produce an accurate and comprehensive invoice is substantial and automating
this is to be recommended. Given the large amounts of money involved it is imprudent to
rely on the Market Operator and their systems without access for detailed and regular
verification. We can advise on:
Systems and procedures to verify the monthly invoicing;
Metrology, telemetry and software development for invoice production and checking;
Development and training of staff to administer the system.
means the established structures and procedures followed by Participants and Service Providers prior to the
commencement of the Interim Period
PPA Administration/ GSA Administration
PPAs and FSAs are complex documents that require great care and diligence in
administration if revenue streams are to be maximised and billing errors eliminated. We can
advise on:
Administration and invoicing for PPAs and GSAs;
Provide automated billing solutions with meter telemetry; and
Periodic audit and review of invoicing, billing and contract compliance.
Regulatory Monitoring and Support
The capacity and energy tariffs are regulated at present. The MYTO Order sets these out,
amended by letters from the regulator, and based on the MYTO Model. The commercial
contract – the PPA – has been superseded by the Interim Rules. Monitoring the regulatory
changes and responding to draft documents and orders from NERC is critical to preserving
the Company’s commercial position. We can:
Monitor regulatory changes and consultative documents issued by NERC;
Advise the Client on the impact of these on the business;
Prepare draft responses and submissions for the Client to submit; and
Assist in negotiations and discussions with NERC.
Regulatory Compliance
The regulatory reporting requirements are onerous and demanding. Mercados can:
Undertake reporting on a client’s behalf;
Train client’s personnel on reporting and set up of reporting systems; and
Undertake audits of reporting to ensure full compliance.
Technical and Financial Modelling and Planning
We have detailed technical and financial models of thermal plant operation and performance
– GenPlan - that are kept up to date with regulatory changes and developments. They
provide support to clients in understanding the impacts of tariff and other changes and
explaining the impacts to Lenders and Investors.
We have a detailed AC Load Flow simulation model of the entire transmission system –
TransPlan that runs on PSS/E proprietary software using a comprehensive database of two
Nigerian Transmission System and input from our own GenPlan. It will allow us to assist
clients with projections of evacuation capacity over time and particularly the likely load
factors for planned plant expansions. We can:
Maintain a detailed financial model for the Plant and project future performance; and
Train company staff in its use and maintenance.
Board Advisory and Training
Each Genco and power project will need to operate in a complex legal, regulatory and
market environment where the key to future profits will be a deep understanding of how the
power market will operate and how power tariffs are negotiated and agreed, how power is
bought and sold and how different technologies and fuel options will be competitive over
time. Our team has an unrivalled knowledge of the detailed operation of the power market
and contracts within the sector. We can provide:
A sanity check on company strategy and business plans;
Alerts on the impact of changes in the market rules and regulatory framework;
Board training to develop understanding of the power sector in Nigeria and the
commercial opportunities that exist; and
Board counselling and support to Board meetings on strategy, financial, commercial
and regulatory aspects of the power sector as required.
Training and Capacity Building
Operation of the newly formed Gencos will require new skills in regulation and regulatory
affairs, in contract administration, in power development and procurement. We can provide
tailored training and capacity building in:
Regulation and Regulatory Affairs;
Settlement Statement administration; and
PPA and GSA administration and operation.
